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.
@@trentonpage6786 The retaining wall block manufacturer and dealer often will help you plan the necessary steps to build a successful wall. Some blocks are so large and heavy that a "gravity" wall can be built quite high without the use of geo-grid. There is no one generic answer for your question because applications vary from one site to another.
Thats an insane comment you are absolutely wrong. You need to get your eyes checked. That material is absolutely appripriate for this build. I bet you any money the wall is fine today. When the backfill is not compacted enough the wall will crack when it has a lot of material to retain. If you used the materials you are talking about then it has a much better shot of failing. The drainage is not the important part here and the type of trench backfill used is exactly correct for what they are doing. While this guys is correct that that is the material you typically use behind a retaining wall, he clearly doesnt have experience when it comes to large walls that have even larger steep hills behind them. 3/4" material does not provide the stability and undue pressure that this kind of wall faces.
@@ar007r To be clear, a minimum of 12 inches of 3/4" crushed stone with no fines is to be placed directly behind the blocks. The material that was trucked in appeared to have at least 50% fines mixed in which is not suitable for drainage The compacted fill being used beyond that point is fine.
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!
Interesting, is there no poured concrete footer for this wall? I’ve seen a lot of conflicting information online, but most of the time they say there should be one
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.
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.
bricks are between 100-150 dollars so at a minimum, the bricks alone are at least 26k (delivery?). Machine rent 2k+. two dumptrucks of fill 16 cubic yard at $30 incl delivery (cheaaaap) 1k. Geofabric stuff isn't cheap either, so lets round that to 1k :). That is 30k if i'm running everything cheap. Sure you can get a discount on those bricks, maybe at $80 if you are extremely lucky and order these on the regular. Somewhere between 40-60k isn't a bad of a guess. Add at least another 10k in labor if your contractor isn't your friend and don't forget to pay your engineer either. Yes, every wall is different, but he could easily drop his regular price with that that disclaimer. Is it well below 30k? I have no doubt, but no regular joe will get that price, of that I have no doubt either ;)
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.
Hi Jeff, the wall has open joints on each brick allowing water to flow through and drainage stones behind the wall. The land is located on a slope with a good amount of angle allowing water flow on a downward direction. Every wall construction is different depending on conditions, slope, location etc. and will need to be engineered. Hope this helps! 🙏🏽😊
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.
Thanks!
Thank you so much Tim! Means a lot for your love support!

Thank you for the time to write this comment.
So would this size blocking be suitable for any retaining wall as long as we follow your guidelines, or is there a height restriction?

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!
Thank you so much Marc! I was very happy with the Turn out! 🙏🏽😊
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!
He didn’t give any costs lol. 100-$150 per brick?? Lmao. 50% spread.
depending on ground and moisture walls don't always need a plastic perf pipe
if ground is dry and hard packed then no worries
Thanks for the clarification Topher! 👍🏽😊
Great job mate, ...Double the price here in Australia - Well done from Gold Coast Australia
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.

Woa.. that's big ops. This looks like an estate build.
The guys did an amazing job! Great coordination, planning and engineering 👍🏽🙏🏽😊
Thank you for your excellent video.
Amazing wall. Is it easier or more cost effective than pouring a concrete wall?
Another great project 👍
Thank you so much Lee! 🙏🏽😊
That wall was one of those projects that may be expensive now but pays for itself in the long run.
I agree! Anything this big of an project is added value to any property, including affected neighbors 👍🏽🙏🏽😊
Interesting, is there no poured concrete footer for this wall? I’ve seen a lot of conflicting information online, but most of the time they say there should be one
This video footage are awesome and helpful for my next project to my home and thank you so much 😍
Thank you! I’m glad I could be of help! 🙏🏽😊
Are those blocks available nationwide (name and manufacturer)?
I’m not sure my friend. It was a company using a mold im not familiar with. So sorry 😞
Hello, can you please tell me what each size of those bricks weigh? Thank you.
Where can I purchase these blocks
Nice! Thanks for sharing. 👍🏻👍🏻
Thank you brother! 🙏🏽😊
That was a serious job. Nicely done.
Curious, why were Police on site? 3:17
Thanks Ivan! Police is my good friend and neighbor 👍🏽😊 police 👮♂️ 🚔
Now, THAT'S A WALL!!!
Thank you! 🙏🏽👍🏽😊
What’s the brand/name of that stone. I’m in Clark County WA.
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.
Yeah but it only took 10 minutes…
Can you do an update on the wall
You use to make videos about your evo 9 right?
What is the name of that block ???
very nice
Thank you! 🙏🏽😊
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 ❤
Yes brother! Thank you so much sa lahat ng pag support! Your just a few minutes away! 👍🏽🙏🏽😊

How much did you charge for this?
Why were the police there? 3:18
Checking for compliance, quality assurance and preventing invasion! Hehe
Wow, nice catch!! LOL...
@@msbgone I had to park it somewhere lol
That wall looks stronger than 99 of houses
So around 60k without labor? Looks awesome.
Thank you so much! It was well below 30K for this one 🙏🏽

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
Stay tuned, this loading dock will have ships in the near future 😉
Who is you dream home going?
Hi! On top of the land 🙏🏽😊👍🏽
😀😀😀😀😀
Bro have you ever heard of excel it would b nice to just do a list instead of talking about it
Lol 😂 exactly
😊
One brick is 100 maybe 150 bucks? Why/where? You need 10K to get knee deep on 50 ft wall?
Good work bro! Ignore the dip shit Karen's
Thank you so much! Don’t worry my friend, just keeping my eyes straight forward 🙏🏽😊
I shall remain in my townhome. 😂
Your home is High Value! Keep it as an investment property! 👍🏽😊
Found ya 😁
I block has 3 bricks???? 260 blocks...
Yes, one 3 brick still is considered 3

Looked nicer before. Not to say you didn't do nice job. I just don't like the look of that block l.
I give this wall a year before it fails. Give us an update in a years time.
I’ll do 1 year update, don’t worry 😉
Sir Joe D,
Can you please kindly tell me what makes you think that this wall is not good enough？
@@pengfa975 have you seen the driveway already on the move

Prices vary. I do know the price… I paid for it 😅. Just email me Tim if you want detailed and exact price. Easy 👍🏽🙏🏽😊
Compared to what was there before....it looks awful 🤷🏻
Thanks! I’ll change it back 👍🏽😊
