A bit or mortar would have solved the 'mechanical' problem. Standard method for 'glueing' blocks to each other.
Daniel Walsh (30 days ago)
I could always see why a retaining wall would fail but I didn't know what to to make it work properly. The foundation material, the type blocks and I have never seen geolock. Yes I like the detail you whet into. Thanks. I would never build a retaining wall because I did not want someone to see that failure and have it laid at my feet and my name. I noe understand what to do and what to use to make it work.

As a professional engineer who designs all types of retaining walls for a living, including SRWs, I can tell you that this video is chuck full of misinformation.
MrBrianDuga (2 months ago)
I just had one of these walls fail. And the blocks weren't hollow. It has more to do with your other points. The contractor didn't put enough crushed stone behind the wall, built it past the 3' mark specified by the manufacturer, and didn't install geo-grid/geo-textile, compacting with a plate compactor in lifts. The failure was at the bottom of a slope where the runoff from the home's roof ran down that slope's base and built hydrostatic pressure. It's been tilting over time from freeze-thaw cycle as well. Absolute nightmare as the wall failed onto a sidewalk and street. Under pressure with the town to fix ASAP and money is not there.

Unless you core fill them with concrete, right? Of course at that height. It needs further specific engineering. But 3-6 courses core filled with a proper base should be fine. Shouldn’t it?

It's more like water got behind the wall and froze, then slowly tipped it over with each freeze.... so you don't let the soil get right up on it, you need a gravel layer.

Looks more like a crappy infomercial than actual advice about the process of building. You are showing a shoddy wall that was built by a drunk monkey and claim that your stuff is better, which is pathetic. Just because my gingerbread house looks like donkey poop does not mean I should use some other material to build it. One should just learn to do it right.

Because he's a salesman coaching guys how to upsell a job. Find a failed wall. Blame the materials and techniques. Offer higher priced materials. Explain a more involved building technique. Not to say he doesn't believe everything he's saying and trying to do a good job. But in my opinion (as other stated here), I think the failed wall above was a drainage issue.

The metaphor was that failure occurs at once, not slowly. I.e., the wall will not  collapse one block at a time. Seems like a valid example.

this wall failed because it should have a concrete footer with rebar running up into the hollow blocks. bad install not bad material. you can see the blocks tipped over because there is no footer and the wall is dry stacked on uneven ground
Nick Noland (7 months ago)
This isn't a CMU wall... Did you even listen?
Nick Noland (7 months ago)
No! No no no... the footer is typically a compacted road base type of material. This system is engineered to be dry stacked. The base and dirt work was done completely wrong in this case but there would be no rebar or concrete footer. The only type of adhesive would be applied to the caps or top course.

how would you build a retaining wall on a steep slope? would you have to level a narrow line for the blocks? this would be a good topic for a video if you do not have one already
None of Your business (1 year ago)
I have a question. I'm currently putting landscaping blocks around my flower beds 2 high in my front yard. It's the typical porch in the middle and flower beds on the left and right. I completed the right side and looks great and perfectly level. The other flower bed on the left side of my porch I want to make it the same height as the right. How do I create the same height? Do I just run a line with a line level from the right flower bed to the left?

When you say a deep base of aggregate, how deep are you talking about? I've watched a few of your videos and have heard some numbers on how far back to go with the aggregate (12"-24" seems to be what I remember), but I don't think that I've heard a number for how deep to go.
Return2Basics24 (1 year ago)
That method of interlocking blocks only (still only 3:50 min mark) would be 'lucky' to last 10 years given the exact right circumstances, if that... It's a building method of "playing the lottery" (am I right? WHY do I know this & most people don't??)

FUDDLEYP JONES (1 year ago)
I see your point but there were several failures here that lead to this collapse. Most importantly, non-existant drainage material, poor compaction. Gravity should keep these blocks in place if the soil behind was stable. stone walls without back lips stand for hundreds of years through freeze/thaw cycles if correct compaction and drainage are present.
Gordon Pilcher (1 year ago)
most fail because they do not have sufficient drainage behind them I've built them up to 3 meters high and drainage is the key  divert water a from the back of the wall with drainage rock  and socked drainage hose so the hose can not get clogged with silt make silt cloth is between the soil and drainage rock

or you can remove all the block and level the dirt. Replace the block and put some bullrock between in the empty spaces and put some concrete segment on top so it won't fall anymore and save a lot of concrete segment.

Salory 2 (1 year ago)
Stanley "Dirt Monkey" Genadek is very misleading. There are many things that make a wall fail. The type of block is very low on the list. Water is the number one cause of retaining wall failure. Lack of proper drainage does make the bulge that Stanley "Dirt Monkey" Genadek speaks of. The retaining wall in this example has improper backfill; which in turn causes improper drainage. Consult a professional engineer for proper design.
Chris Ryan (1 year ago)
Here in the UK retaining walls would be mortared with drain pipes through the bottom blocks at intervals to drain water. The old way of doing it was called Dry Stone Dyking where each stone is picked to interlock with each other. Some dry Stone walls have survived for hundreds even thousands of years.

scotty362100 (4 months ago)
maxdecphoenix Who do you think you are shitting? Your example that you have repeated several times is your complete misunderstanding of your supposed proof! The damn glass jar breaks because the water around the mouth of the jar expands when it freezes, and breaks the mouth of the jar. Because glass cant bend with the expansion of the water, NOT because it sucks it up into the jar, or magical molecules.. It will break even if you seal the mouth of the jar to the pan and add water to the pan outside of the jar. IDIOT! There is no way on gods green earth no matter how many times you say it that water is going to suck up the inverted openings in those block and defy gravity, PERIOD!
Nick Noland (7 months ago)
maxdecphoenix - You're way over thinking the water thing Sir. How many fractured or broken block do you see? Hmm none that's right, the block are fine and the install failed. So.... Improper base and no drainage system behind wall. Fail! Although what you say is not false just over analyzed. SRW systems with PROPER install can withstand freeze thaw cycles for decades.... *mic drops
maxdecphoenix (1 year ago)
In addition to Daniel Rose has said how hydrostatic pressure will push water into the voids, the big problem isn't the water itself, it's what the water does when it freezes. If you fill a glass jar with water, put it in the freezer and wait, the next morning you can expect to find the jar exploded. The reason is that as liquid water molecules lose energy and freeze their atoms restructure and their apparent volume increases. By 10% at 0*. Even if you leave head-space, or the jar isn't totally full, it will still expand in all possible directions equally, and explode the glass. It can do this to stone as well. When liquid water gets trapped, as it freezes it can expand and explode blocks. Broken blocks don't trasfer their load properly and as water pervades and then freeze in the crack, it can apply lateral forces which push blocks apart
Flavius (1 year ago)
The bricks in this wall were upside down. However, that is not always the case.
Daniel Rose (1 year ago)
Yes, that can happen. The hydrostatic preassure lightens the back end, allwoing water to flow inside the block, but at the front it is trapped. If now the hydrostatic preassure is lowered, the water can be trapped. For sure you won't find gallons of water inside, but enough to damage a block.

I dislike this video and I'm not a contractor. This video is being used to demonstrate a different purpose and persuade people into by expensive building materials furthermore, raising the final price of the whole project. Those blocks used for that retaining wall on the video are perfectly good for that specific project...but in the video the presenter fails to make enfasis in a better installation. As a DIY guy and caretaker of my own property I recommend those blocks anyways.... just have someone with the skills to do it or have a contractor that's knowledgeable enough and who won't try make you spend more money than what you really need....

nuttynut242 (7 months ago)
I dislike this because the video missed the main problems and the narator doesnt have a comprehensive understanding of the retaining wall failure mechanisms (this video is fine if its coming from an amateur but not for a self proclaimed pro) and the video sounded more like a promotional video for the preferred block. 1. The lip shear key system of the failed wall is fine and the void of the blocks are meant to be backfilled with concrete or aggregate. We have sucessfully used similar system for walls up to 6m high for a main road bridge abutment with a 100 year design life. We have also built 3~4m high walls with limestone blocks with no lip or pin connections, just pure friction between the limestone blocks. You just need to know what the design limits are and use them appropriately. 2. Badly prepared base, unless your retaining wall is in a desert with constant temperature, we cant avoid water softening or shrink/swell effects at the base of wall, to get around this we usually burry 1 or 2 blocks and sit the block on a fairly inert strip footing / leveling pad of compacted crushed rock or lean concrete. 3. Insufficient wall depth. This is a gravity retaining wall, which in principal rely on its weight and size to hold soil/load back. Rule of thumb suggest you usually need a depth of 50~70% of the retained height. You can either do this by adding more blocks or, we can usually reduce the width requirement by changing the variable such as: reducing the wall load, increase the weight of blocks by filling the voids, improve retained soil properties by replacing or compacting the soil behind the wall or change the angle of the retaining wall. 3. The failed wall doesnt appear to have any back of wall drainage, which is typically* needed for landscaping walls, Note typical, not always required. However, it is impractical to have a wall drainage to take on the role of a surface water drainage. Usually we would either make sure the grade falls away from the retaining wall, if thats not possible, we will add a U-drain behind the wall to divert surface water away from the retaining wall. At bigger/higher retaining walls, we may also add a capping layer of compacted high plastic clay, like bentonite to reduce the volume of water infiltrating to the back of the retaining wall. This is coming from a professional engineer who design and build real, non landscaping retaining walls.

Stanley Jones You said it right. This wall failed because of what looked like zero foundation work. Disliked this vid because as a contractor myself I know bullshit when I hear it.

Nice tutorial, clear and to the point. One thing you might want to fix may seem nit-picky, but I think it may have a negative impact, right when you don't want it to. At 7:02 your onscreen captioning reads; Compliment your competition! and, It makes you look proffesional! ...Even typing that here in comments is getting red-underlined by auto-spellchecker. I freakin' know you're a professional - but you gotta spell that word right. If you freeze the frame at 7:02, it's actually kinda funny. Cheers.
Great point that I missed during editing. Unfortunately I can't fix it now.

Never motored- they are meant to be mortarless so the walls can let water pass through.

Thank you for the video and your time . I need to build a retaining wall here in Texas and I have pure clay that expands and contracts a few inches inches from soaking wet to bone dry . I will have to try and find your product in my area or something similar . I had troubles hearing you with my volume all the way up on the laptop and the video player , is it possible for you to increase it in the video a tiny bit .
I can on future videos. Use 3/4 clear as base-6 inches minimum will help with expansion and contraction. If your soils are real bad place filter fabric underlayment on the sub base before sticking in your 3/4 clear. I have another more detailed video on the process.

What about blocks that have the lip but are hollow all the way through? If they are installed properly (with crusher stone) won't they drain properly?
Yes you can use them the stone that fills the hollow core actually helps connect the blocks together and is better than the hollow from the bottom blocks that you see in this video

There is nothing wrong with the block that was used. It was not installed correctly. Period. Some of the reasons you gave for it failing are pure BS. Water filling up the cavity and freezing? Are you serious? Any "pinned" wall that is installed in this manner is going to fail as well. Been installing walls and planters made out of this type of block for 15 years.
It was a combination of Poor installation and poor block choice.
