How to Build a Retaining Wall Start to Finish

How to Build a Retaining Wall Start to Finish
Here were building a 500 sq ft retaining wall. I go over all the different steps through out the process. The blocks we used are Allan Block AB Classic. The retaining wall was designed by an engineer and has three layers of geo grid.

[@CyclingYYC]

Hey Sean, I've watched a bunch of your retaining wall videos and I want to confirm the process for replacing a 32 inch retaining wall that's collapsing: -dig down 12 inches, compact base -put down 4 inches of 3/4 inch gravel, compact -lay first blocks, level -put landscaping fabric behind wall, French drain pipe -stack additional layers of blocks -backfill behind wall with 3/4 inch gravel, compact -wrap landscaping fabric back -cap stones -beers with the boys

[@srmcontracting]

Eric, Your on the right track! I would do a 6" base and make sure 1 row of blocks are completely buried. So if your blocks are 10" tall, you will need to dig down 16". Also I never use fabric behind walls. Unless you live in an area where the soil is very sandy I wouldn't recommend it. Thanks for watching and let me know if you have any questions.

[@srmcontracting]

You're welcome, this wall was designed by and engineer so I believe they took that into consideration. With that said I don't believe we added any additional load to that cinder block wall. I think we did just the opposite by building up the grade. Now if that cinder block wall where to fail it would basically go unnoticed because the fill dirt would keep it in place.

You don’t use a filter fabric between stone and subsoil? I’ve always found it adds a layer of insurance. Keeps stone from weeping into the surrounding soil.

[@srmcontracting]

No sir, here is eastern PA the soil has a high clay content. This will clogged the fabric very quickly and put hydrostatic pressure on the wall. I've built several walls that have been designed by engineers, none of which called for vertical filter fabric behind the wall. I would only use it if the soil was very sandy. Thanks for watching!

[@boblewis1303]

@@srmcontracting makes sense. Thanks for the info. In my area we have a lot of sandy soil. No matter what you do the ground is still somewhat soft and really like to hold water. So filter fabric is an absolute requirement for us. I use 2 separate stones for my base material. 3/4 clean for about 7/8ths of the base at whatever depth is required then the top 1/8th I use 3/8” limestone chips. Really helps lock everything together when tucked into the filter fabric trench liner.

Nice job. I've watched other videos on retaining walls and yours looks to be the correct way to build one.

@@fabricioalmeida348 Its great work and you can make good money doing it. Theres two major differences between hardscaping and landscaping. The first being the jobs take much longer. Most of my jobs take 1-3 weeks. The second is finding guys, it's a lot easier to find a guy that can run a landscape crew then it is to find someone who can run a hardscaping job. If your a small company like myself, then you should find someone to run your landscape jobs and you focus on building the hardscape side. Another factor is all the equipment is expensive.

No tie in to the neighbors wall, no return in that corner, half the yard is graded into that corner, and you're in a cold climate? What's to stop the soil from filling the clean rock (I know you added a cloth on top, but soil slides sideways too) freezing and pushing that corner out? Is the stone lip enough of a setback to hold the wall in?

[@srmcontracting]

The neighboring wall is a CMU wall, the wall I built is a segmental retaining wall. You should never tie these different wall types together. Yes I'm in eastern PA, we go through many freeze thaw cycles. We never put fabric vertically behind retaining walls, our soil has a very high clay content and will quickly clog the fabric. Once that fabric clogs it will put hydrostatic pressure on the wall and lead to failure. There is at least 18" of clean stone behind that wall, it will take 50 years for the soil to migrate through it. In addition to the lip, we also put Geo Grid which acts as an anchor behind the wall. The blocks are also filled with 3/4" stone, this also holds them together. I've built many walls designed by engineers and this is how it's done in my region. Thanks for watching!

very nice. I was surprised that you put in as much geo fabric as you did. Typically you see it every every 3-4 feet in walls taller than 4 feet. I have seldom seen it at all in walls under 4 feet. I was also surprised to see a 2 drains (toe and heel) instead of just 1 especially with wall under 4 feet. Finally, I was puzzled by the fact that your lawn level is under the top course of your wall. Typically the lawn should be higher than the all so runoff goes over the top of the wall rather than in behind it.

So, are the “heal” and “toe” drain pipe solid or perforated? I understand wanting to do a great job and building a wall that will last forever, but being there really isn’t a down hill grade issue, all that geo fabric is unnecessary and over pricing the project by hundreds of dollars. IMO

[@srmcontracting]

Both pipes are perforated. I'm perfectly content with over building everything that I do. I explain that to all my customers up front. Also we had the pull permits for this job and have an engineer design the wall. So the wall was built per their design. Thanks for watching.

[@kyesniper]

Even if that amount of grid wasn't required, I'd still use it. Overpricing a job by a few hundred dollars on a job this size which likely was priced at $15,000+ is nothing for cheap insurance. The way they built this wall, unless there's a flood or earthquake, it will probably never fail.

I have been designing MSE walls for 35 years. One comment - the geogrid is supposed to be installed 90 degrees from the way you did and stretched tight before backfilling and compacting to take the slack out of it. Each section of grid is to be overlapped 6-inches. You do not roll it out parallel to the wall.

That is a large wall and there are many variables. Your market, site Access, commercial or residential all play a big factor. This wall would require an engineered design and the wall will require geogrid reinforcement. Assuming at least 1' of the wall would be buried. 7' x 300' is 2100 SQ ft add about 10% for waste, cuts, etc. 2300 SQ ft x $45 = $103,500.

3/4 clean is not a base material! Clean stone does not compact, your base must be as hard as concrete. Class5 or modified stone is a base material. Your drainage pipe is useless when the water can flow right past it and under the wall into the base. Otherwise beautiful job

Sorry but I have to disagree with you. 3/4" is great base material and compacts very well. Ive seen 50' tall retaining walls holding up parking lots built with 3/4" clean stone. Not to mention, this wall was designed by an engineer and it called for 3/4" clean stone. As far as the drainage goes, you are correct the water will flow past the pipe through the stone.

@@srmcontracting clean stone contains absolutely no fines and therefore , will not compact. Guaranteed. Clean stone is for under a concrete slab to prevent freeze and thaw. A retaining wall base should not be built with clean stone. Have you ever compacted 2A modified and then 2B clean. The compactor will bounce on the modified and on clean it will move it out of its way. You do a great job but I would never trust building my walls on clean.

​@@MrBmxbrawler I've built many retaining walls and yes I've compacted 100 of tons of modified. Modified gives the effect of being more compacted but I assure you 3/4 stone compacts just as well. At the surface it seems loose but the angular nature of the stone locks them together. ncma.org/resource/srw-design-manual/ if your interested download this manual and read chapter 2. Its shows "Well-graded gravels, little or no fines has excellent Shearing Strength when Compacted and Saturated". I don't want to argue with you, that's not what my channel is about.

@@srmcontracting You do a great job. Everyone does it a bit differently. We set walls on compacted modified with a thin layer of screenings for fine tuning.

@@srmcontracting Thank You sooo much for that design-manual link!

Looks good but do yourself a favor don't use those hollow blocks, don't matter how good job you will do they will give you trouble down the road.

You wasted the time using a string line, walls still aren't straight, compacting anything over 1" at a time was another mistake. 12:15 is that corner supposed to be gross or was it planned?

hi, how much does it to build it?
