All that equipment and no plate compactor interesting.
Right. Three years later and no settling that I can discern. But definitely not standard procedure.
Crushed stone is 75% compacted when dropped from a skidloader bucket, may even be a higher percentage. Also the block weighs 60-80lbs most likely which basically compacts the stone even more. Not saying this is the way we do it but sometimes I feel like some of the stuff we do is wayyy overkill... it also almost looked like they were using pins which helps ALOT
I built this wall. It's 4 inches of 57 stone on top of hard Chert natural ground. It's 94 percent compacted when dumped and beat level with a 12lb Hardscapes rubber hammer. When we used crusher run or 89-10 or we are building on soils that aren't hard we use a plate tamp excessively. There was a hand tamp and blocks turned on their sides and patted where the wall steps up on the ends used in this video when the base was laid.
Great learning this. Thanks for the work
Sooo, no footing poured? Was it bedrock below?
As a structural engineer with 46 years of experience, this is what I noticed. The block used is a hollow core block which is supposed to be clean stone filled to provide strength & most importantly, interlock. (Check manufacturer's specification sheet) I did not see any of the cores being filled as the wall was being built. If that is the case, this wall will fail over time regardless if geogrid was used. What kind of geogrid was used? It look like a soil separation geomaterial, not a bidirectional geogrid. If it was single directional geogrid, it should be laid from the front of the wall back into the hillside, not parallel to the wall face. Code requires the (missing) drain pipe behind the wall to exit to daylight every 40' with the exit to be extended 6-8" past the face of the wall (to prevent destabilizing of the wall base). I saw no pipe or exits in your video.
Since the wall is greater than 4', US building code requires the project to have an engineer's review stamp. In most municipalities across the USA, the local town engineer or building official would also review the plans prior to construction. Based upon the mistakes made in the construction, this must have been eliminated as well.
Make sure to keep your insurance policy paid up to date and hope it includes "completed operations" coverage. This project is a lawsuit waiting to happen and all the liability will be on the installation contractor.
Must be why it is "Dirt Cheap".
My suggestion to all involved is to talk to your product representative on direction of proper segmental wall construction. www.ICPI-NCMA.org has some great training classes now that will teach you and your help the proper and best methods for construction.
With a little more knowledge & experience, you can do some great work. I wish you good luck in the future. ... TED
I’m the home owner. This is my channel. Not the company, Dirt Cheap.
There is a 4” drain pipe that exits to daylight and extend the length of the wall, but not every 40”.
The geogrid, from what I can tell, is laid from the front of the blocks, back into the wall min 2/3 (I think) the height of the wall (according to design). I’m not sure if the blocks were core filled or not.
@@tjb-inc the grid is weaved. You can see it front the front side of the wall. I think it is every other layer. Company gave lifetime warranty.
@@tjb-inc where I live, permits and inspections are not required. The company did submit the topo to an engineer that design this wall. But I agree with you on you points. Before hiring I did hundreds of hours of research. Blocks are to be core filled, geogrid weaved (friction force etc). So now I am a little concerned. Is there a way to closely monitor any changes in the wall?
@@Srvelis82 I went and reviewed the video and the geogrid was open and laid correctly! As far as failure, look for any bulges in the wall over time. You have a lifetime warranty so that is good news. Hopefully it will stay upright for many years.
@@tjb-inc 35-40 years minimum I hope!!! 😂
We core fill and tamp down each coarse behind wall we never stack coarses without filling and tamping especially with no adhesive interesting
Looks good! I’m almost afraid to ask… but how much did this cost you? Lol
This looks great. I need to build a wall about the same length and hight. What was the estimated cost in 2020? Thank you
I wanna say $31-32per square foot. Ours came in at 30 K.
1 day , sure whatever you say LOL
Are those just dry-fit? And no piling or anchors? Doesn’t seem like that would be very structurally sound. Granted I’ve never built a retaining wall, nor researched how to do it, and the video I watched before this they sunk telephone pole sized pilings 8’ into the ground 3-4’ apart. 🤷🏻♂️
Every other layer has 6-8 foot of geogrid that extends back into the hill side with #57 gravel on top. This wall design is based off of the topography of the hill and current engineering standards. I sure hope is sound.
@@Srvelis82 oh, okay. So you have horizontal anchors making the wall you built effectively 7-9’ deep… deeper than it is tall. Yeah, that shouldn’t fall over. Thanks for the info. I’ve always loved retaining walls.
@Kevin Corapi I didn’t do the work. But contact a block supplier and they can probably hook you up.
Cost of this project?
WHY NO CONCRETE POSTS AT THE BACK.
What’s the size of the blocks?
Big. Like 70 pounds each. I’m not sure if the actual dimensions.
err... danger wall...
Please DM me or post price. Very interested to know what a project of that magnitude should cost in your area. Thank you!!
$32/linear foot as of 2020.

👍👍☕️☕️🫖🍇🍒🍉🥧🍕🌮
One day 😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂 no way
It might be helpful to narrate and explain what you’re doing and why. I’m also an engineer and doings things right is critical if you want it to last…
Looks like its been done right to me
Aside from there being 0 deadman anchors it's pretty good
Theres a reason it was done in one day LOL
No doubt
