WHY Retaining Walls FALL down - How Most people Build them Wrong

Retaining Walls NEED geogrid to stay standing! In this video I'll demonstrate why it's so important to a wall over 4 feet tall, that has a slope on it or under a surcharge (holding up a building or parking lot).

[@mikewatts122]

Another thing to add to the equation is the necessity of soil compaction between grids. The issue of the wall blowout in your video is from poor compaction between grids behind the wall. That's why that grid had dropped.

[@theshuz]

Stanley, check out Practical Engineering's video on engineered soil. He literally dropped a wheel of his car on a pile of sand and I think just paper towels. It is very well done and shows how strong engineered soil is...

[@matthewdeaton7961]

I've watched all of your retaining wall videos. And built my own 4 for wall with a layer of geogrid. The only thing you haven't shown is how to actually test the soil for silt. Idk what that entails but I'm sure you have some tips on testing the soil or bad vs good soils! Thank you for all the amazing videos!

You explain things well my KZbin friend. Do it yourself people don't always have that trade like mind that we have learnt over decades. That's why are so varied in trade skills.

Practical Engineering aka Grady, did a great video on engineered soil. Opened my eyes!

[@andyisnotyourfriend]

Good video and great point about the geogrid. You should do another one on the issue of hydraulic jacking and proper drainage of a retaining wall. I've seen many walls fail due to lack of a drainage system to remove water (pressure) from behind the wall. Also, for any home-gamers...use a stamped drawing by a licensed engineer for any wall over 4' tall. Most reputable suppliers will provide one for you at little to no charge. If you build a wall improperly and it fails and god forbid someone is hurt or killed, you may be held liable.

[@Dirtmonkey]

Thanks for watching and for the suggestion!

I have seen glue injection used to hold a sand bank behind walls. It can keep ground water from bleeding through the blocks, together with a bubbler drain behind the glued sand. Very good video on how to stabilize with geotech materials.

[@Foreverandever431]

Geogrid is great I love it. Great for roads. Problem with geogrid and why it is not specified for retaining walls generally (MSE) walls excluded is you have to excavate significant amounts of soil from behind the wall to construct. This normally is cost prohibitive in most cases.

An important point with a pinned connection wall block....DO NOT USE SOFT GEOGRIDS LIKE STRATAGRID. THE PINS WILL TEAR THROUGH IT, AND THE WALL WILL FALL DOWN. STRATAGRID is fine for tongue and groove blocks, but not pinned blocks. Use a rigid geogris, like Tensar, for pinned blocks.

Hey Stanley, I’ve watched a ton of your videos and I love them. So informative and super helpful. I’m starting a project for my sister who wants to build retaining walls on the side of her property that’s at approx a 50 degree slope. Height of the hill is approx 25-30 feet and hypotenuse of the hill being 65 feet. Could you give me your thoughts on how you would tackle this? Mind you she would like usable seating or planting areas on the terrance’s I front of each retaining wall built and doesn’t want any walls over 4’ tall. After watching your videos I do feel a lot more comfortable doing this project but would love your ideas on how to make sure this project will not fail and last for as long as she owns the home or longer. I do plan on putting in geo grid, using Versa lok and 24” of angler 3/4” stone/gravel behind each wall. Geo grid would would need to be at least 4’ in length for each 4’ retaining wall built. Am I missing anything? Would I start with 12” down for drainage on the first row of blocks? This area gets a ton of water during the rainy seasons which makes me anxious on the proper way to do this. As far as surcharge, at the top of each 4’ retaining wall there will be a min of 8’ of flat area to minimize the load. Minus the seating/tables etc... that she plans to put there.

[@juliuscaesar3000]

Can you do a video showing when to implement terraced retailing walls and how to do it correctly. Also how you could do that to steep land that is right next to a steep driveway where the seating walls would have to run perpendicular to the driveway.

Probably a silly question, but am curious... Is it possible to increase the height of an existing retaining wall? Or to build on top of an existing retaining wall? For example, instead of Terrace wall, just remove the top terrace and build on top of the lower wall. Thanks

[@havanaday9981]

What if your taking down an eroding wooden wall that hasn’t been pushed out but when you put up a paver block wall you can’t get down into the dirt to put Geogrid down without excavating 6ft down and 6ft back?

[@KevinCoop1]

I'm about to have a wall built by a contractor. After watching your videos, I've said versa block and no fabric on the back side of them. Also said I want Geo grid. What I'm not sure about is what to backfill behind the blocks with. The soil here is high plastic clay. It expands a lot when wet. Wall at highest point 5'. Holds soil back, and is a half circle about 12' radius open on inside of circle. What do you suggest for backfill? Respectfully, Kevin

[@jbcartledge]

I am currently in the process of building a small retaining wall up against a hill. 25' long, 24" high. Is geogrid neccessary for such a small wall? We will be back filling with rock for drainage and soil on top for planting.

Now I am worried! We bought our property just over a year ago. There were existing stone retaining walls that are decades old. We placed our home on cinder block pillars on top of the clay soil. There is a hill behind it with no retaining wall, a hill in front with a partial retain wall. Do you know of anyone in eastern Kentucky that I can contact to check this out and see what I need to do? I wouldn't even begin to know who to contact. 😱

[@edsiler3260]

In several videos you've said not to use fabric between a wall & the fill aggregate, how about between the undisturbed earth & the aggregate? Was considering doing this to keep the earth out of the gravel fill. I'm working in Missouri clay, and have been at this a while, solo & all by hand. 3' deep & the unsupported ground has stood firm for months now with no collapse. (lots of delays) Base course is in, 2nd course shortly, then start backfill before adding - so if the fabric as described is advisable, now is the time. Should I, or not? BTW, using Versalok std block. And yes, I know I'm working slow. 62, health conditions, and grandkids living here will do that to ya!

[@jso2332]

My home was built in 1964 in an area with large slopping hills. Most of my retaining walls have failed =(. Some of them have fallen over, while others have split and cracked due to the amount of pressure of the hills they are retaining. Could I send you some pics so you can help me assess how screwed I am? It seems like the walls directly in front of our house are fine, meaning I dont see any leaning or cracks, but I am hesitant to do any work to this home knowing that our retaining walls we built without proper drainage or geogrid.

[@adama9561]

What happens when a wall has geogrid every two feet, but it doesn’t go back on a 1:1 ratio to the height of the wall. What if it only goes back on a 2:1 ratio? So on a 10’ wall the geogrid is only 5’ deep. Does geogrid need to go into native soil or just recently placed backfill? Is proper 1:1 geo grid depth more important towards the top of the wall of bottom of the wall?

Would a light duty pickup truck on a 4ft wall constitute a surcharge and require geogrid?

[@chrishanson9748]

Certainly it would - truck itself may not be heavy, but it's weight is distributed to four points, not quite big themselves. Also it is not a static weight - when you move out, and especially when parking, when you apply brake, dynamic pressure increases. It may not be after the first parking, but few months and you may see results.

[@theoriginalbubba1036]

Hey Stan,Is there a way to use the geo grid on a poured concrete wall? My thought would be to put it in the gap between forms and cast it in, flap it up out of the way until backfilling (in layers) so it acts as a deadman as well as a stabilizer. Would it just be overkill?

[@mikewatts122]

A poured concrete retaining wall has a keyed foundation that goes into the retaining side of the wall. Normally going under the retained earth 1/3 the height of the wall. Have it engineered for your soil, load and earthquake zone.

[@theoriginalbubba1036]

I appreciate your input.This was a hypothetical question... no plans on building a wall right now. Would it be belt and suspenders, and elastic waistband maybe. how about geo-tech fabric unattached? Seems stabilizing the backfill would do more good than harm as long as drainage isn't effected... if no one ever questions current technique, innovation never happens... I'm a seasoned heavy equipment operator, and I often have to deal with engineer induced problems...I try to learn (thus watching Stan and others) So I'm not just a dumb stick monkey seat warmer.

Would you use Geogrid with a concrete wall?

I beg to differ on sand binding properties...
