Thanks!

This retaining wall will probably not fail. I say that because it was not built according to engineering specifications. It is clear too me that the aggregate that was trucked in and placed behind the wall is not meant for drainage which is essential for proper hydro-static release. You can see this at the 7:00 minute mark as the plate compactor is leaving a smooth finish after passing over the back filled material which does not happen with clean 3/4" crushed stone. Regarding geo-grid installation - the first layer of geo-grid on top of the 2nd course of block looks to be the proper length that your engineer called for, but the contractor did not excavate enough soil to lay the geo-grid out far enough. This is not too critical for the bottom of the wall, however, the top layer of geo-grid is not long enough considering the 11' proposed height of this wall. This is a critical point where that geo-grid needs to be anchored far enough back. The geo-grid should be no less than 12' in length. At the 1:44 mark you will see that the geo-grid is bunched and soil has been placed on top of it. This is a mistake that can cause failure because it almost renders that section of geo-grid useless. Proper installation - once the next course of block is placed over the geo-grid and you are ready to back fill aggregate and soil, the geo-grid should be pinned at the limit of excavation to hold it taught. The pins can be removed once soil is placed. The probable success of this wall is attributed to the weight of the blocks and that each course is set back a few inches from the course below it. Always use crushed stone that will allow water to pass through and increase the quantity behind the blocks if you are back filling beyond that point with clay soils. One other critical point is the footing for Segmental Retaining Walls (SRW) of any size, use 3/4" crushed stone. For this wall using these 24" wide blocks, the footing should be 48" wide x 12" deep using 3/4" crushed stone compacted in 2 or 3 lifts depending on size of compactor. Everything that I have stated is not based on my opinion, it is based on approved engineered plans that I have used to build retaining walls over the past 30 years. I have had a very inexpensive education witnessing and studying failed retaining walls built by inexperienced contractors (often landscapers) and homeowners. I have also witnessed improperly built retaining walls that are still standing after several years and some that are slowly listing. I don't care to say that it will probably stand the test of time, I say that when I build a wall it will definitely stand the test of time.

Those workers did a huge job! Wow the time lapse with drone footage was awesome. What a huge project, hope it all pays off for you!

Most people never discuss the COSTS! Thank you for that since it IS the most important thing to consider for any project. Nice job on the wall too!

depending on ground and moisture walls don't always need a plastic perf pipe if ground is dry and hard packed then no worries

That was one of the better large block wall videos I've found. Good work.

That wall was one of those projects that may be expensive now but pays for itself in the long run.

Very insightful and thank you so much for posting. Strongly reco a summary cost on actual at the end of your post. That would have brought this up a notch on what actual Labory+supplies+material+equipment rental = total. That's the formual of every bank account and no graded paper until that part is turned in before class is over. Still very helpful and will be following for more later. Kudo's for this effort. Wow!

Great job mate, ...Double the price here in Australia - Well done from Gold Coast Australia

This video footage are awesome and helpful for my next project to my home and thank you so much 😍

Woa.. that's big ops. This looks like an estate build.

Another great project 👍

nice work, did you have to compact the sub base, then add a base stone and compact that first? Didn't see in the video if that had to happen.

Now, THAT'S A WALL!!!

Are those blocks available nationwide (name and manufacturer)?

Hello, can you please tell me what each size of those bricks weigh? Thank you.

Bro have you ever heard of excel it would b nice to just do a list instead of talking about it

Nice! Thanks for sharing. 👍🏻👍🏻

That was a serious job. Nicely done. Curious, why were Police on site? 3:17

You're in Washington? Been following you for years.... Looking to do the same project, but smaller. Pagpalain Ka Ng Diyos, bro. Tacoma here btw ❤

You use to make videos about your evo 9 right?

What’s the brand/name of that stone. I’m in Clark County WA.

Washington is always raining in a period of time this wall will collapse who ever is the engineer not well made if this is my project i will secured this with round bars and needs a concrete cement with a good foundation in the ground and post and it’s columns. But it’s looks good before and after.

very nice

Lots of gaps, no porous rock behind the wall to facilitate water escape, I didn't see any drain tile going in (might have missed it), geo grid is a disaster..... This wall is doomed.

Damn it looked rustic and cool and nice. Now it just looks like a loading dock 😵 like hold on. Why is there a house at this shopping plaza

How much did you charge for this?

So around 60k without labor? Looks awesome.

I shall remain in my townhome. 😂

There are a lot of inconsistencies in this project. For example: It was engineered for 12’ geogrid but that grid looked to be about half that. You can’t give a the price of that job because the price varies across the country……say what? If your wall was engineered, why did the manufacturer run out of blocks? Who dropped the ball on that one? Chances are the mfg ran out of material and the chances of the next batch matching are very low. Overall this job was a resounding failure, and as other I’ve seen in other comments, the wall will be next.

Why were the police there? 3:18

Who is you dream home going?

I block has 3 bricks???? 260 blocks...

Expo

😊

Good work bro! Ignore the dip shit Karen's

I give this wall a year before it fails. Give us an update in a years time.

What king of drainage did you use behind the wall?

Looked nicer before. Not to say you didn't do nice job. I just don't like the look of that block l.

I expected you at least to say "this wall cost this much to build....". Oddly you don't know the size of the blocks you're installing which tells me you know very little about this type of wall and what it should cost to build. Buyer beware.

Compared to what was there before....it looks awful 🤷🏻

Impossible, only on tv….
