[@tonyennis1787]

If I was paying for a fence from you, how much would that metal-post fence cost me versus wood or chain-link fencing. If I am paying for a fence, I expect it to last a certain agreed-on amount of time and perform a certain task. Beyond that, I don't care what the costs of individual components are. Sure you can drive the metal post in 2 minutes. But I don't care; it isn't my problem. For 500' of fence, what's the total cost?

[@Stars333Bright]

My house was built in 1996 and the fence posts were drilled and set with a pre-mixed concrete. I have replaced the fencing four years ago and all the posts were still solid and therefor used again. My (engineer) neighbor was not keen on the dry mix but is now happy we went that way due to cost savings and long life. No screws or nails were added. Great video full of very good information. Thanks.

[@jeffbguarino]

I put my fence in in 1985 and used 1/4 down limestone, crushed rock. Everyone in Canada uses it for wooden posts. It gets as stiff as concrete and you can break it up and pull out the posts. I use a car jack and pull the post out, so you can do this in a confined space. How do you get a concrete set post out of the ground ?

[@marion-bs3qh]

Wooden posts nearly always snap at ground level. This is not only the point of maximum leverage but also where oxygen, soil and water all come together to promote rot. I always set the post in concrete, domed to shed water but also give the post lower part three coats of bituminous paint first, up to 6" above ground level to protect against rain backsplash. I also give the join between the post and the domed concrete an extra coat of bitumen after the concrete has gone off to seal it. Plus, I put a wooden post cap on the top of post to protect the end grain. 20 years service is possible here in the UK doing it this way. It depends on the quality of the post wood too though I supposed, there's more fast-grown post timber around nowadays, wide growth rings = lower strength.

[@tonyennis1787]

When I moved into my house, the owner had made a very attractive horse fence using PT landscaping timbers for posts. But those timbers are only PT'd to about 1/8" deep. After a few years, the centers rotted out leaving a very attractive but extremely fragile fence. One day we had a wind and they all came down.

[@libertyvilleguy2903]

Good information, thank you. I agree with you on the newer posts not lasting as long, because they’ve come from faster growth trees. I’ve used red cedar in outdoor applications (posts, decking, furniture), and I’ve noticed I don’t get as many years out of it as I used to.

Well I would not hire you if you think anything like this is something to compliment. You never EVER put a wood post directly into concrete. Not pine, not oak, not pressure treated. Never ever. If a contractor ever tried to suggest that when putting in fence posts I would throw him off the property. You place ABS Pipe into the concrete, pour gravel the bottom of the pipe 3" then place the wood or metal posts in ABS pipe through a glued pipe cap and silicone the post to the cap. That is the MINIMUM and will last the normal required 50 years, the shortest amount of time any household or commercial project should last.

I spoke to a fencer a few years ago and he said most people make the hole too big. He recommended just a couple of inches around the post and he used a very narrow spade so he did not desturb the surrounding soil. Some gravel in the bottom and very little concrete is needed. I've used this method a few times now and it really works. Great video by the way, very interesting and well presented.

I'm astounded at the engineering and technology behind fence posts now. When I replaced my back yard fence I did the wet-mix method of pouring in a bag of redi-mix and adding water while I held the post steady. Worked fine but I see there's room for improvement. Thanks for showing the different methods, it's been very informative.

Same here. In my neighborhood there was an empty lot that grew 12" to 16" grasses. After a rain it was easy to pull up a handful of grass with a nice clump of dirt clinging to the roots.

[@MnktoDave]

Thanks for the interesting video. I'm just a DIY home owner in freezing MN and had to dig all my holes by hand, but when I built almost 250' of my wood fence almost 40 years ago, I used 2 string lines for alignment (1 for total post height, and 1 across the top face of the 4x4 posts) then I dug 8" wide post holes as close to 48" deep as possible, and added a 6-8" thick compacted layer of 1-1/2"to 2" crushed granite rock (no fines) under each post. The posts were set directly on top of the crushed granite to provide water drainage, then packed tightly with dry concrete while adjusting the posts to match the string lines, then I finished by pouring about 2-1/2 gallons of water over each post hole, and letting it slowly soak in. I kept the concrete about 4" below the grass line so the water had plenty of room to sit while soaking, and there was no need to support any of the posts to grade, because the dry packed concrete did that for you. Later I topped the holes off with back dirt, and the grass filled in nicely around the posts. Since I'm always working by myself, I've found this is the easiest way to make all of the posts come out right on the money, and the concrete is always very strong and solid. None of the posts I set this way has failed, and the fence is still strong, and looks great to this day. But you HAVE to add water over the dry concrete in the holes (and let it soak in) or else it takes a LOT longer to harden, if you simply depend on the rain. And the 4' deep holes with concrete, keep the frost from moving anything around.

[@PageMarker1]

That is one hell of a lot of work there. 40 years later is a testament to your efforts. Well done!

[@bushwackcreek]

A old fence builder who has since passed hand-dug all his corner post holes to 4 feet... in caliche (here in Texas). He had a special shovel he'd inherited from his father called a "telegraph spoon". Use a digging bar, post hole digger, a sardine can and finally that telegraph "spoon", he could dig and clean out a 12" diameter hole. He'd set the post with tamping alone and they've been doing fine for 40+ years. Here in the Texas Hill Country, caliche soils are superb for road base and long-lasting fences.

[@lpdirv]

Live in an area where frost line for code is eight feet, we have had frost in compacted areas to 12 feet. We find screw-piles work best and for deck posts we use sona tubes to keep the outside of the concrete smooth. Have also used elephant feet with sona tubes for larger point loads and have never had any issues. Farther north we have to deal with permafrost, buildings will sink into the clay. Fun fun.

One of the best options is stone pack around the post. Step 1. Place the post Step 2. Pour in the stone (angular, jagged stone) Step 3. Tamp it down Step 4 done and your posts will last 2x as long because the water drains away. Concrete acts like a sponge holding the moisture up against the wood.

I recently mixed over 50 bags of that concrete mix. The number 1thing i found to get a consistent mix is to measure your water volume. This gives you a perfect mix every time. Also if you have any amount to mix get a small mixer and it will save you a lot of time and effort.

[@davidg8032]

I've mixed a lot of bags where I would use the hose to add water several times until I got it to the consistency I wanted. Like you said, measure your water to get a consistent mix. Plus, it's much easier to mix when you initially add the total amount of water needed as opposed to a little at a time. The instructions on the bag for the correct amount of water are very accurate.

[@hddoug72]

If aggregate plus cement... 3 scoops rock plus water first then cement and 2 parts sand and the add sand to proper consistency. This is what's works best for me

[@spacefightertzz]

Yup, measure the water volume. I had bought some concrete water measuring cups made in china... All I know is that I had to add extra amount of water than what is recommended as labeled on the concrete mix bag... And I was using a small eletric concrete mixer, I measured the water in my chinese measuring cups in the american pints, but there was still dry concrete powder at the mixer was spinning... So I had to measure and guess the extra water of how soupy it should be back from my previous experience of building concrete house foundations. (I measured out the amount of water specified. I don't know if it was liters or pints, but specs were the same wether it was liters or pints... There was still dry concrete powder after I added what was labeled on the chinese concrete measuring cup. And I had to correct the water measurement. It wasn't twice the amount of water but it was near)... If the concrete mix recommended an amount of gallons then that would be so easy to measure from.

Always provides the most study post and if the frost moves it, it's very easy to shake and pack it back into place.

Agreed!! And yet sadly, while treated posts I have removed from 30 years ago, are fine, many post installed only7/8 years ago are useless. That's all due to our glorious WEF leader Bush Jr decided to remove all the good stuff out of our treated lumber so it's pretty useless (yes, even ground contact treated lumber).

[@jonjohnson3027]

Where I live, I can get a "5/8 minus" driveway mix made of crushed basalt with a lot of fines. It's an excellent material for packing around posts, better than the local soil which is damp and squishy most of the time. (It helps that the gravel yard is next door.) For tamping, I have a piece of 3/4" steel water pipe 7 feet long with a cap on one end; it's the perfect length and weight. I pack in "lifts" rather than filling the hole all at once then tamping. I'm in an old riverbed, my soil has a lot of rocks up to cantaloupe size (who needs metric measurements?). Sometimes digging holes, especially in dry season, they'll blow out in a cone narrow at the top, don't want to be putting that much concrete down the hole! The posts end up being set just as solidly as with concrete, but can still be removed and reused when your fencing needs change, and the semi-porous nature allows it to dry better in the dry season. But, I can see where wet mix concrete can be a labor savings, making it a wash or possibly cheaper to use concrete versus packed material. Also, not everywhere has a suitable gravel mix for packing.

[@papparocket]

I used a similar commercial "paver base" I set 16 4x4 posts for my big garden. I used a big solid steel wrecker bar like they have in the video to tamp it. The big advantage is as you say, the aggregate lets the water drain quickly away from the top 2"-3" which is where there is enough of both water and oxygen to support biological growth that is what causes posts to rot. If I had access to commercial equipment, I would get a pneumatic tamping rod with at least a 6' rod and a ball end. A two person team would go pretty quickly. One person shoveling in aggregate into the hole from a wheelbarrow while the other runs the pneumatic tamper. Pour and tamp in about 6" at a time and in a few minutes the hole is fully packed. Beside long life for the post, the other great thing for a commercial operation is absolutely no cure or set time. So once you have the posts set you can immediately start with building the rest of the fence. Plus, when comparing to wet set, there is no mixing time or cleanup at the end.

[@IowaKim]

As a kid my dad used gravel to pack. He was pretty old school.

[@ifandwhen-kl2cr]

Where I live the frost line can get as deep as 4 feet. Here’s the process: 1. Auger 12” holes to a depth of 6 feet. 2. Pour 3 bags worth of mixed sakrete in the empty hole. (The purpose of the concrete is to prevent downward settling.) 3. Drop in the post. 4. Fill the rest of the hole with gravel while tamping. Done. The gravel acts as a sleeve, allowing the ground to heave without taking the post with it.

Back in the day, I used to be a fence builder around Dallas. It is good to listen to new ways of doing things. With the foam and dry packing and such. Thanks. One thing I will add, for what it is worth. About 50 years ago an old farmer hired me to drill some holes and set fence posts. He insisted on "yellow cedar" or "cypress" set in pea gravel. His reasoning was the Texas heat. In the summer concrete and wood, will shrink away from each other, allowing water to enter the crack between the two. Pea gravel would allow the rain water to dissipate and would allow the pea gravel to readjust around the post, keeping it tight and straight. Later, I learned the crack between the post and concrete (in residential fences) would allow fertilizer to rot the post over time.

We planted lots of Wooden post fencing, never used Concrete its a pain to remove when the post rots off.!

Engineer here, but electrical, not construction. But I take some issue with saying dome'ing the concrete won't make a difference because soil will build up anyway. That may be true for an unmaintained fence, but what about a homeowner who makes sure his fence posts are high and dry because he doesn't want to build another damn fence ever again. So if I hired someone who didn't set the concrete above grade and sloped it away from the post, he would be a rookie, even if he didn't brace his post!😂 Also, I would have plumbed and braced the foamed post ahead of time and not wiggled it, which would weaken the bonding. Also would have shaved away the foam to create a slope away from the post. You can see in your video that the expansion of the foam created a nice bowl around the post for rain to pool.✌️

Any vibrations will just tighten post more If ever need to remove use a shop vac to suck everything out. Can then reuse what's in vac to reset. Also pour melted canning paraffin over tops to seal pores. Wrap tops temporarily with duct tape to create lip or dam.

LOL I've used bracing on posts for two reasons: in town, kids on alcohol and drugs will too often mess with posts -- the bracing isn't so much bracing as deterrent for vandals; outside of town or on the edges because elk love to come along and rub against isolated posts, and the bracing discourages them. As a teen I helped put in a fence where the farmer used round posts with a sharp point. He'd made a rig using an old chain saw that sat on top of a post so three of us teens kept the post in place while he started the motor, and the motor pounded the post in. The other way I saw posts just pounded in was with a tripod holding the post upright and a tractor pounding the post in with its scoop (with a steel pipe over the post top to keep it from splitting). I like the machine you've got much better!

While working for a Concrete Foundation contractor 45 years ago, I was tasked with pouring a footer for a Basement. On Friday we set the forms in the bottom of an eight foot deep hole. On Saturday and Sunday it rained and fill the hole and turned it into a pond. On Monday morning we were tasked with pumping all the water out before the Cement Trucks arrived at 10:00 AM. We got all but 2 feet out and the trucks pulled up. We poured the Concrete where we set the forms which were under water. On Tuesday we finished pumping out all the water and there was the Footer full of Cement and Hard. I was 18 years old and was amazed that the concrete had set up under water. My boss told me Concrete will get harder if it is kept wet while curing, thus the reason Concrete is Mixed with Water. Using No Mix Concrete does not mean not to use water, it only means you do not need to mix.

Exactly! If you lay a concrete slab you also want to sprinkle it with water now and then. It gives the concrete time to settle and harden evenly. Pouring a slab in hot and sunny weather without sprinkling it is a recipe for cracks in your finished product.

I worked on a farm with an old guy who had built every kind of fence for decades. We used pea gravel, tamped it and then tamped dirt on the top 6" or so. In his experience the posts were less likely to rot off because there was a some drainage.

[@dblake58]

I've used gray gravel, 3 inches in the bottom and tamped tight around the post. It's really sturdy , stays in place and will be so much easier to put up if needed, and drains any moisture away from the post.

[@janetbent2339]

Personal experience by an old lady DIY. I'm north of the Pacific Northwest on Vancouver Island in BC Canada (think pretty warm/pretty moist). I sunk 4" pt posts in a well drained area and used wet concrete, leaving a 4" collar at the top that I filled with dirt. They were good for about 20 years but eventually rotted off. The fence in the front, same posts/concrete leveled to the ground and they're still solid after 35 years. Gotta take all the different conditions into consideration. Thanks SWiFence, I enjoyed watching the experiment!

[@actontreadway1168]

This is great feedback. I really wondered how long posts last if done right. I've gone a little overboard after digging up some posts that weren't done well on my property. I now pour the concrete without the post and finish it off about 5" above the ground with threaded rod embedded in it. I think this method, while a little more work, will last a very long time and the wood can be replaced without pouring another concrete pad. I made a bunch of wood molds to pour the concrete in a nice square shape above ground. Downside is there needs to be some kind of triangulation to keep the posts rigid, however.

[@ASDasdSDsadASD-nc7lf]

Correct. You never EVER put a wood post directly into concrete. Not pine, not oak, not pressure treated. Never ever. If a contractor ever tried to suggest that when putting in fence posts I would throw him off the property. You place ABS Pipe into the concrete, pour gravel the bottom of the pipe 3" then place the wood or metal posts in ABS pipe through a glued pipe cap and silicone the post to the cap. That is the MINIMUM and will last the normal required 50 years, the shortest amount of time any household or commercial project should last.

Back in 1963, I worked for a fence company called Anchor Fence. Their residential chain link fence posts were anchored with a galvanized steel shoe bolted to the post about 6” below the grade. Two galvanized steel angles were driven at 45 degree angles into the ground. After they were driven, the galvanized shoe was tightened to the post. It was a much stronger hold and allowed us to install a fence completely in one day.

[@ItsDaJax]

My mom had had her house since about 2000. The old fence was replaced a few years ago, except one portion of it, none of the post were rotted. The people who put the new fence in put some of the post in straight dirt and two of them rotted. The wind blew one down last year during a storm. I replaced that one. Concrete itself will absorb water, which is why I wish I could've painted the in ground part of the post. I've seen concreted in post where a portion of it was somehow exposed below the concrete, that could be a factor in rotting in the concrete, too. I had put some dry mix in the bottom as a base to be on the safe side.

Two-inch sch 40 2-3/8 on 7-foot centers set with concrete 3.5 foot deep and you will not have problems. My fence is almost 10 years old and just went through a hurricane. wood post set in concrete or soil are laying on the ground all around town. I also build overhead line and use hydraulic tamps. Never did the foam because of the expense but if the price was right that would be the way to go. meter poles set in concrete rot at ground level or break in the wind because they do not move. Your idea of stopping below ground with the concrete is good. I also like the drive in steel fence poles you showed at the end. I would probably use that system if it was available over wood. Wood in general is not what it used to be. Old growth trees with tight growth rings were far superior to the farm raised trees of today. That is why we have poles from the 1920's still standing out in the oilfields. Tight grain. When I do use concrete on poles I dry place it. Because I do not want it to be perfect, I just need it to firm up and hold not be a monolithic block that will hold water and rot. When I was a kid in the 70's a lot of the ballfield poles, we set were tamped with oyster shell. Oyster shell is the best for tamping. Water moves through it, and it compacts and hold like nothing else. Oyster shell used to be available at low cost but today most of the shell is taken back to the beds and used to build oyster reefs. thank you for the video.

I use 2x4's to create an 18 inch square form at the top, 4 inches above ground level. Fill it with concrete to the top of the form and slope the concrete away from pole so water drains away. Never had frost heaves or other issues, and it looks good. I would never put dirt around a wood post as it will rot away with the bugs in the soil, especially with the new "pressure treated" crap they sell nowadays. One of my fences is over 35 years old with no issues.

[@kameljoe21]

I have a really good way to make super strong gates. I know people who have put in huge concrete for gate posts only for them to bend. While my idea does cost some money and some time to do it does work. You got to decide how big of a gate you want and type of fence you are connecting. Then you trench out a hole 2 feet wide 3 feet deep. Then build your gate posts with a H brace about 8 foot long and then connect the H braces via rebar in the trench and fill with concrete. We have welded these gates up at the shop with some cross braces to connect over the top of the gate to prevent twisting. A few we have done the tall cross bar. Set it in the ground on bricks. This will keep the rebar up and out of the dirt. Which is why you go down 3 foot. The fill up the trench with concrete Leave about 6 inch left in the hole and cover with gravel. Gravel will allow you to keep grading the road and repairing it over time. The other way to to install a cattle guard. Yet you have to build them right. No one ever does and I watch cattle jump them all the time. You have to make it at least 8 feet wide and the fence post needs to be a V shape. This forces the cow to have to jump clear over 8 feet and not about 4 or so feet when they stand at the single post and jump that tiny gap. This also allow you better access to clean out the guard are from under it.

I’m curious why do you test the dry pack without adding water. The instructions in the quickcrete bags we use suggest adding water. Testing the dry pack without adding water defeats the purpose of testing the dry pack doesn’t it?

[@thedivide3688]

There are many companies that just pour concrete mix in and tell the customer the rain will set it over time no need to worry. Dry pack means pouring in dry. Adding water after the fact unless you trickle water for many hours will not soak through. The dry mix before it begins to absorb water is hydrophobic (afraid of the water and will not mix). When people grow plants we have this same scenario. They say oh we watered for 5 minutes daily or poured a couple buckets of water on the plant. Then you come dig up the plant and they never ended up watering more than a couple of inches of soil and the plant is dead.

[@kayvan1225]

If you pour it dry then build your fence there are no gaps from pounding on your fence when you built it. after dry tamped in cement fence build wet it down make a pyramid top so water go's away and rain will do the rest in the right climate. If you build it with wet cement then water gets in because you pounded on the fence when it was being built it moved the fencepost and created a gap after the pour unless you wait 30 day for it to set up most people build it one day after they've pour it. Concrete will not be hard yet and you are making a gap between the post and cement for water to get in for fast rot.

I set fence posts in concrete and some in dirt in 2002. I used rot resistant, locust posts in a moderately wet climate - 30-40" rain per year. After 10 years I noticed some of the of the posts in concrete were leaning. After 15 years a few of the posts in concrete were completely gone at the level where the post met the concrete. Not rotted , just disintegrated. Upon examination and analysis I believe rain pooled around the concrete and post and since concrete has a pH of 10-11 it formed a lye type liquid and simply ate through the wood. Sort of like Drano. The posts set in dirt are still there and fine.

Let me see. 5 bags at 60# is 300# of concrete, mixed with water. OR just a bag of foam that weighs perhaps 2 pounds and takes minutes to set up. I have run a lot of posts with just the foam and if you do it right, one bag per hole. This clearly was your first foam post; you were very tentative. Better process is simple: auger the hole, set the post where you want it, use bracing to make sure it stays there and doesn't move. Grab bag, burst seal, shake as hard as you can for 6-8 shakes, cut top and pour in hole. If you don't mix it enough it doesn't fully expand. If you don't move fast enough, it starts to set in the bag. Bracing is so you DON'T WIGGLE THE POST WHILE THE FOAM IS HARDENING!!! (which you did). You will create gaps in the foam. After its dry, several hours, use coarse wood hand saw and saw off the top slightly proud, pack dirt over it to repel water. 24 hours later, Posts don't come out, don't move. One bag foam at local hardwarebig box is $16. One bag of concrete at the same store is $5. if you auger the hole at 9" instead of 12", it may take 2-3 bags of concrete instead of 5 OR one bag foam. Done right, I've never had to use 2 bags foam. So, $10-15 concrete or $16 foam. 180# vs 2#. Huge effort vs no effort. I first used foam about 8-10 years ago. Done well over 100 posts with foam; I have a quarter mile of fencing on my property. No post has come out or become unstable yet--hurricanes, bumping with mowers, etc . The last 50 posts I set in foam were a couple years ago, 5" vinyl, just my wife and I set them in a weekend. We were both 70yo. Saved at least $2K in labor over having someone else set in concrete. So, IMO, foam is strong, NOT MORE EXPENSIVE than concrete and the better solution.

Here in the coastal PNW, dry set is fine. I have never seen it fail. Our soil is so wet that the concrete is hard in hours and cured in just a couple days. If the weather is unusually hot and dry, I just add a little water between bags and sprinkle the top to keep it wet.

Just a homeowner DIY'er here so please grade me on a curve but here's what worked for me. When I had a pole barn garage built years ago in rural NJ and if memory serves me well, I observed that they would auger a hole, drop in a concrete pad, set the pole, and pack in loose gravel around it up to a certain level and then pack in dirt on top. I don't recall seeing any concrete mix used at all. So I later used the same technique when I built my own run-in shed for the horse and for the post-and-rail pasture fence, and for the fence along the front of the property. I augured or dug down about 3'+, pounded down a few inches of gravel and set the post. Then I started pounding down more gravel around it a few inches at a time and checking level each time. At some point maybe halfway up I started pounding down dirt on top of the gravel. The dirt there was clay heavy so I imagine that it contributed to the holding power. The fenceposts I got were used and I had occasion years later to replace a few thanks to the weed trimmer chewing away at it and they were not easy to pull up, and in fact had to use a bumper jack and chain to get it started. Both pole barns are doing just fine 30 yrs later too.

Mightve been 6x6s but set them for metal farm gate doors, Drilled out holes in posts for rebar going through center 6 inches apart up bout 3 foot on bottom of post, Found I kept rebar slightly longer than holes were wide so when I went to set posts rebar bent slightly upward gave posts subtle quick twist back n forth to set ends of rebar into hole walls a bit which in the end not only did rebar have a barb like effect in ground but rebar stabilized post while I mixed n poured concrete so didnt need any supports, Posts havnt moved a hair in last few years even with heavy gates constantly hanging off the 1 side of them, Ill be forever proud of that gate, After that Ive done it same ever since for Wifi Posts and Fence posts etc, Ive got tools n equipment to mix concrete and dig holes far quicker n easier but some reason I just prefer to do things the hard way when comes to things like that…

Nice presentation covering a number of post setting methods and there weakness. Time consuming but staight fine gravel and the same aggregate dug out makes for long lasting posts. Packing in lifts is slow work but it does last. You can drive all around the country and see old 100 yr old fences done this way that are still as solid as the day they were set.

1: Dig holes 2: Spray bottom of posts with Rubber Undercoating higher than hole depth: 3: Place post in hole: 4: Poor in dry concrete: 5 : Level posts. 6: Add water to concrete.

I've always set my deck and fence posts with a hybrid of wet and dry.... auger the holes, set the post in and fill the hole with water to the top, then shovel or pour the mix in around the post... it sets just like wet, and you don't have to wait the long game for drypack. I wouldn't do a slab or sidewalk that way, but it always worked great for posts.

I used the SIKA Foam in 2013. Post is still in great shape

[@alfriedar]

Yeah, that’s what I would’ve thought. Throw the dry and throw some water and throw more dry and throw some water in. You would’ve been fine. That’s been my finding but I really like that you did this the way you did it.

Awesome! Back when I did masonry, I was helping my mom build a 6 ft wall on one side of her property. Since it was in California, the building codes in the area are pretty strict and my best friend and I were hired by my mom to dig quite a deep footing. She did all the measurements and calculations, though, but she's a mathematician so that made total sense and it's probably going to stand longer than any of us who built it is still alive, even when the "Big One" earthquake finally does come (and I will say that I will be annoyed if I don't get to experience this earthquake). I build bushcraft stuff in the area for shits and giggles and two things have been slowing down by building: the first is that I'm trying to make the shelter look like its surroundings and the second is to make sure anything I build above head level won't come down easily in even a 9.0 earthquake, which is 10 times larger than we are supposed to expect here. There's lots of clay around here and, having stepping in some quicksand while wading in the area, I can verify how much it tries to pull your shoe off when that happens. If I hadn't though about earthquake safety, I might have already built something using that clay since it's easy to get relatively pure clay and sand underneath it. Since I'm trying to build things out of whatever I can find in the area, I have considering using wood instead of steel as a reenforcement. There are not enough grasses and reeds to make rope or else I'd use the method where you reenforce the outside rather than the inside of the structure. I like the shape of those posts and the idea of driving them into the ground. I have done something similar when I built my fire pit and the shelter above it. There was only a little cracking in the clay and sand mixture that I made and I used branches so fresh that they actually sprout every spring and I'm hoping they grow trees there because that will only give me more cover and more strength for my structure or at least it seems to me that will be the case. Anyway, thanks for the new things to think about!

I agree here, pushing the post in is the way to go. I used the 2” pipe (you called it 2 3/8” pipe which is 2” pipe. Steamfitter/Pipefitter here, if it were 2” it would be tubing, not pipe) because it was essentially free and made my own hand pounder. 30 years later I haven’t had a post fail.

[@steved5871]

Really good video and information. The one point I differ on is in south Florida we don't have frost but if the top of the concrete is below the grade it will hold water and the posts, even treated post, will rot at the point. We had a landscaper put up some trellis's for us. Most of the posts he put the concrete level with the surface and they were still good 12 years later. He must have been running short on concrete or it was the end of the day but the last three he left 8-10 inches below the surface and they all rotted off level with the top of the concrete.

I live in the panhandle of Florida. I learned my lesson on setting posts in concrete. Hurricane Ivan simply snapped the 4x4s off at ground level. Now, I don't use ANY concrete in the holes. I just pack the sandy soil. Storm comes along, the post get wobbled out a little but don't snap. Then I just straighten them up, repack the sand, and I'm good to go until the next tropical storm or hurricane.

I used foam for the first time 3 months ago, it is quick, simple and dries super fast!

[@glennelliott708]

Pacific Northwest rains rot posts at ground level with great regularity. Since posts have to be removed, dig hole, use cinder blocks 4x4 with square centre, pound the post into it. Set in hole and pack navvy jack around it. In 7-10 years time the post has rooted at the soil line. Did the navvy jack out, pull the post out of the cinder block. You can use the cinder block again for replacement.

[@drfirechief8958]

I just had a very bad storm down here in Texas. It damaged my wood privacy fence and will need to do some repairs. Thanks for all the info, it will help tremendously.

[@e_d_v_a_u_s]

As a homeowner, I love the Sika foam product. Sets up in just a few minutes, so it makes fence building that much quicker.

[@giro994]

Nice bonus material. Hadn't thought about steel posts, but we used a similar driver for the posts and anchors of a sutter wall. I think his tool was called a Stinger, with different adapters for the different parts of the wall. Our soil in Tahoe sometimes has big rocks, but we only had to change locations of one of the 6. For the verticals, a double jack worked well on most of them, but the stinger tool made it easier, especially if some medium sized rocks were hit.

Thanks for making this video! Wish I'd seen it before I built my backyard fence about ten years ago, but it's all good! I used quickset concrecte then and that worked just fine. One other advantage of the foam mix vs the dry cement (in a humid environment): If it sits long enough, the bag of cement will absorb water from the air and solidify, whereas I imagine that won't happen with the foam. I really enjoyed the video and informed content-subscribed! Also, saw the bucking bronc and flag on your hat. I grew up in Cheyenne and Laramie, then moved out East a long time ago, but it's great to see someone from home!

Thanks for watching!

[@tacticalskiffs8134]

Love the video. At 20 ish, you mention that the only reason we need concrete is to get the hard socket fit around the post. There is another reason, you are for any given lateral loading distributing the pressure over a larger surface in the ground. However, whether that maters or not in a given application is an open question. We have the same problem in high performance wood structure. Metal fastenings are required to get loads off or in. But metal to wood usually ends up in damaged wood. So if you use a poured epoxy socket, you get the tight fit that you mentioned, plus a much larger area (4X the fastener size) to spread the load, and all of a sudden it is as effective as a welded stud.

[@tonyennis1787]

I dry-poured all my chain link, and some 4x4s too. Never had a problem but all my work was residential, for my house; no industrial uses. I also used a 6" auger since that's all I had access to. Can confirm that if the hole is off you get to do plenty of extra shovel work to move it. I also used The Devil's Tweezers for some of the holes and that's so !fun!. But it was just quicker than driving to the rental store for the auger when I only needed 6 holes. Hint: don't skimp on your post-hole diggers; spend some money on them. I would water my dry pour unless the soil was wet; just a bucket on top when the post was plumb. All the posts stayed plumb. And by the next day I never had unstable posts or broken concrete even when I did a really bad job on centering the post in the hole. My logic brain tells me that wet pour must be the best way but I never did it. edit - I never braced any of my posts. I didn't know anyone did that. I never had the time or materials for that, and most of my work was with steel posts anyway. edit2 - Christ on the Cross, why would I put nails or screws into my post. If something is going to pluck the post out of the concrete, vertically, I have bigger problems.

[@KenOnaMission]

Awesome test, on various methods. I used the wet pour system, 30 inch deep holes in New York. I painted roof tar on the bottom 2 feet of my 4x4s too. Thanks for the info..

[@bhut1571]

Good point about the slope of the concrete edge. In Northern Ontario, frost acting on the edges of the post or rough concrete will lift it up. In a few years in clay, a wooden post sunk 4' down will be at least 4 " higher.

[@Coppersmithkane]

It's nice to see when knowledge becomes wisdom, thank you, that is very useful.

[@SWiFence]

My pleasure!

[@dsloop3907]

Foam is being used by the electrical utility in my area where the poles are being replaced with much taller ones, as the grid is being updated for all the new homes. I tried foam for the first time last year, it seems to be good. And a lot easier to carry.
