- How to build a retaining wall on a slope - This customer's backyard has a pretty steep hill so we installed a retaining wall to give them a level portion. We built a 3' retaining wall with geogrid reinforcement. The wall we built has curved corners and steps built into the wall. We also built a paver patio with a fire pit.

I have a major slope in my backyard. My husband and I will attempt to DIY this over the next couple years. This video was so helpful! Thank you!
Now this is a properly built retaining wall. You have a new follower in me.
Thank you!
Nice wall. ALLEN BLOCK IN SANDSTONE. NICE COLOR. I worked at a cement plant in Edmonton, Alberta Canada & we made those blocks & other blocks in the Allen Block collection. Ran a forklift & had to stack the pallets in the yard for the Yard guys to load trucks with. I did my whole yard with seconds( blocks that had defects that could be seen. Hell, I did not care. It was free. Saved me $ thousands. I have AB Courtyard along my driveway & AB Jumbos in Rocky Mountain Blend around my house. Took about 12 pickup loads & loading & unloading by myself. Thought I was going to bust the springs on the truck. Build good muscles working with that stone. Take care & God bless!
The simplicity on how you thought how you completed this job made me subscribe. I’m new to landscaping and I think I’ve found one of many great pages. Thank you
Thank you for subscribing, I appreciate it!
Finally someone puts in some geogrid!
Great video! I think this is the best video I've seen on how to build a retaining wall correctly.
Now that is what I call a professional job! Well done.looks awesome.
Thank you
Great craftsmanship, attention to proper practice, and handsome execution. Thanks for sharing.
I appreciate the use of a proper structural retaining wall block. This looks like AB classics. Should last many years with no issues.
Are they, thought, or they just resemble one? I can't see any interlocking feature, nor they were cemented, or had vertical bars holding them in place: what would prevent them to slide away at the first heavy rain?
@@Beregorn88 these are filled with clean gravel which “interlocks” them together. You can drive a piece of rebar or rod if you would like but it’s not required. Allan block walls are meant to flex for freeze thaw cycles.
You and Stone Cold do some excellent work
I was waiting to see if you guys put in the Geogrid. Nice work. That wall will last. This is the difference of you get what you pay for.
Excellent video! Man that was was built strong!
In Australia we use very similar blocks to the however our footings are always concrete with reinforcement added and we fill thw blocks with 20mm "no fines" concrete
We dont have freeze and thaw conditions to worry about down here
Look forward to watching more of your videos
Thank you for sharing your building process! I appreciate you watching!
Man what a beautiful job
Wow , that looks so nice and it looks like it will last as long as the house. The homeowners have a functional a pretty back yard now! Great work !
Thank you!
Very nice work! Wow, a lot of labor involved in that wall vs the Redi-Rock.
Thanks, the one downside to the redi rock is it looks like plain concrete. A lot of home owners want something a little nicer. These are Alan Block but like you said it's a lot more labor intensive.
Looks amazing! You are truly the best at what you do. Thank you for another very informative video.
Thank you very much, glad you enjoyed it!
Actually, it’s hard to say if they’re the best because they’ve never competed in the retaining wall national championships. Until then Fred is the best.
All looks good from here !!!! Great job fella's!!
Great work! I appreciate you taking time to do the video. Thank you
Over building never fails. 😊
Better overkill than BEING k!//3d
First time viewer and I liked your work. Just subscribed, and look forward to more good stuff.
Beautiful work just trying to get some ideas for my sloped yard looks amazing
Thank you
Peace Family,
"Magnificent build."
Respect
Thank you
Nice work guys. Looks like that’ll last for a good 50yrs barring anything catastrophic.
Yes it will, Thank you
That's gorgeous, bro!!
Awesome job.
Love the tunes too.
My dude in red hitting 95% compaction for sure 😂💪🏼 Nice video sir!
You always have to put the big guy on the compactor! Thanks for watching
awesome work just curious as to how that tree will do with those roots being cut out?
Luckily the tree is still holding up. The home owner knew there was a possibility the tree could die. Thanks for watching
Beautiful job
Looks very nice. Whats the approximate quote for a job like this?
Love watching a master tradesman work! Is there a follow-up video to this one?
Nice job man is professional 👏
Just found your channel great content and the wall looks fantastic 🇦🇺🇦🇺🇦🇺
Thank you!
Somebody actually respomds to their comments.
. nice work.
Amazing work! How much does this cost on the average. Need to do this for our mew House. Thanks for the info
Looks good, you definitely build them to last!! I'm in! subbed and waiting for more good stuff!
Thanks for the sub I really appreciate it! More to come
How much does a wall like this cost the customer?
great job - love the stairs!!
Thank you!
Great job - very impressive
Thank you
Absolutely Amazing!
Well done!
Thank you I appreciate it!
great footing as a foundation, that is how u build retaining wall footing.
That’s some hard ass work but buddy packing that gravel looks jacked af lol. Looks great!
Nice work
Thanks for watching
Great video! Some questions. 1. Can you use 3/4 clean as your base instead of the modified rock? 2. Does the drain need to be sloped toward the discharges? 3. Do you cap the ends of your drain pipe or leave uncovered?
Thank you, yes you can use 3/4 but your drain would need to be in the base. The drain pipe can be flat or have a slight pitch. This drain pipe shouldn't get much water at all. Cap the pipes or put some fabric over the end. Thanks for watching
I need to do something similar for a carport.
One end of the carport will be on a poured driveway but the other end extends past the driveway and down a dirt berm.
I’m wondering what I need to do to secure and build up some block so that the carport is level with the driveway from the dirt drop off.
It’s not a big drop really.
I was thinking of getting some railroad ties and dead manning them into the berm and just building it up with ties as needed then filling the rest in with dirt and a gravel top coat.
Any thoughts?
💯💯💯 Good job
Thank you!
Very good job, can I ask where to get that top block cutting machine please, that is very useful.
This is great work. I wish you were in my area. I'd hire you.
09:30. smart move to add soil over fabric
I wish you were in my area. That's exactly what I need.
Best of luck finding someone
also, the hollow portion of the blocks must be filled with cement mortar to create adhesion for each block further strengthening each block with the rebars of course.
No. This wall is intended to let the water flow through. What you’re suggesting defeats the design and structural needs of the wall.
So no concrete fill is needed? How do the blocks stay in place, with the weight of the rock filler and gets stronger as time and water goes by?
@@benhead77The fro ts are notched
Thanks for sharing. I'm guessing you had to pull a permit for this wall due to the surcharge and height?
Your welcome, this wall is under the height requirements for a permit in this town.
What type of cinder block did you use please?! Love your videos - beautiful work. Thank you!
Thank you, it's Allan Block
I’m currently in the process of building a block retaining wall 20ft long by 3ft tall. I’ve got my trench dug and leveled. I’ve looked online and I’m confused by the type of base gravel type I need. So do I need to put fabric on top of the dirt, then fill with gravel, then start my base block layer. Then do I keep putting gravel behind the wall or do I backfill with dirt? If anyone could help or guide me in the right direction that would be much appreciated
No mesh/fabric for base layer unless you have sandy soil
I liked the work very profissional , what brick you used for that wall ?
Thank you, it's Allan Block
Nice work! What was the cost of this whole project with material and labor?
Thank you, ballpark for a retaining wall like this is $20k. Your region and site accessibility play a big factor in pricing. Thanks for watching!
Awesome!!!
Thanks!
Very nice and great video . I have a question on the 4” water drain, where do you place on the other end ? I see it drain down the hill
I LOVE IT! Do mine next!?!?
👏🏻👏🏻 amagazing
Looks very nice. But, shouldn’t the French drain be deeper?
Thank you, In this case the drain is where it needs to be. If we would have used 3/4" clean stone then the drain would have been at the bottom. But we used a crushed stone base (3/4" modified). Thanks for watching
😮😮25 years ago, I built a 4 foot wall with no knowledge, hand tools, and a 4 wheeler to pull rocks from the land. I wonder if it is still standing. Wish U tube had been around back then. Lol.
Beautiful
Thank you
Hi looks amazing job Thanks for sharing this kind of videos with us I have a Curious how much is the cost for that job Just example doesn't have to be exactly priced
Ballpark for a retaining wall like this is $20k. Your region and site accessibility play a big factor in pricing. Thanks for watching!
Srm . Kompany, 💪👏👍,very good job s 👍, thanks youuuu 👍. Me working England seven years, same jobs, thanks,
Questions about that big tree root you cut during the digging phase. With that tree being on a slope, could cutting a root of that size kill the tree, potentially knocking it over in a storm? Its so close to the wall im afraid it might pull up the soil and destroy the wall too. Would it have been better to leave a gap in 1 block on the base layer to leave space for the tree root? Just fill and level the gap in the blocks with stone over top and around the root? Or would that make the wall deform as the root grew bigger over time.
Reason i ask is because i have an old drystacked flagstone retaining wall on a slope, also supporting a flagstone patio. Its probably 50 years old, and is in need of repair. There are massive trees right up against the retaining wall, and im going to have to dig near them, but im also concerned with killing the trees. Not sure if i should just slap some morter inbetween the dry stack to help it hold awhile longer, or just rebuild completely and dig.
That tree is definitely dead. Just running heavy equipment within the tree drip line can potentially kill the tree.
Your crew does great and artistic work, and where does the water that is being drained off by the drainage pipes coming from.
Great job! ❤️
Thank you!! 😊
Great job! That’s a hell on a lot of rock! 🥵
Thank you! It sure was
Looks great! Very nice. Do you have a video on the patio?
Thank you, I did a time lapse of the patio. Let me know what you think
ruclips.net/video/9vFffqOt6mE/видео.html
That was a great tip on the benchmark. I would have screwed that up.
So question of a novice. Why do you not use mortar or cement between blocks? Just curious. I'm about to start a little project of my own in the next few months
This looks like Allan Block which is a segmented gravity wall. This wall is meant to heave and flex thru the seasons the mortar or cement would just crack. The spaces between blocks is also meant to help with drainage thru the face of the wall.
How much did a big job like that cost? Starting to think about doing something about that size (by pros, not me)
deer just chilling in the background lol
Awesome 👍😎
Looks nice. Wondering, why no concrete in the stones, instead of gravel? Just thinking concrete would hold more?
Stone drains water..
Nice beautiful
Appreciate the video, very detailed.
Just wanted to ask any reason why you didn't use a fabric to seperate the soil?
Also wouldn't it be beneficial to use geogrid in the base?
Thank you, We never use filter fabric behind walls in our area. Our soil is mainly clay, that will clog the fabric and end up putting pressure on the wall. The only time engineers recommend fabric behind the wall is if the soil is very sandy. You can put geogrid in the base but it's not necessary, just make sure you have good compaction.
The work is pretty awesome. However, it would be better to have dug deeper so the drain would be deeper.
It looks good...
No landscape fabric separating the drainage stone from the soil?
Yeah all good, the problem as homeowner i can't budgeting 40k to get my backyard done , at some point i need it DIY with a helper
Looks good
Thank you
My daughter has a retaining wall 75' across, made of 8x16x8 concrete bricks, 6 courses high. With a 1' x 12"x75' concrete pad under the build.
(Sd.,Ca.) . I came from phx and this would of been 3' x 12" x 75' and phx is flat, present wall contains (in my dreams) 18' with a 12' rise behind it. scary!
Very cool video. Thanks for the share! quick question - do you never have enough back pressure on the wall where you need to glue /rebar the blocks? just wondering under what circumstances that should be done? Cheers!
Thank you, these retaining wall blocks are meant to be dry stacked and filled with stone only. I believe them being dry stacked only allows for some lateral movement without causing wall failure. Thanks for watching
@@srmcontracting
I have a large project that requires such retainer walls. About 8 feet tall
It’s very hard to find a contractor who would do the right job. It’s not my trade so looking to subcontract
@@nyhis5533 Where is the job located? Also when are you looking to have it completed?
@@srmcontracting
New York. As soon as possible
@@nyhis5533 I've got the same type of job in NY, did you find anyone you like?
Looks like the older homes were built on more level ground. You never see slopes like that here in south Florida. retaining walls are rare too as many areas the ground is coral rock and is its own retaining wall if you cut the grade.
It's a mix where im at, some areas are flat farm land and others are neighborhoods built on a mountian. What part of FL are you from? I used to live in Ft lauderdale when I was in middle school. I still have family in Palm Bay.
@@srmcontracting Key Largo and Miami. Mostly coral rock here.
@@srmcontracting I am in Cape Coral and if you’re in the area , maybe you can do one for me .
Curious. If your only putting 3/4 clear from the drain up, won’t you have freeze thaw issues with all the water that will stay under the drain?
How much does a job like that cost?
In the UK the footings would be field with concrete. Then the blocks layed on top. And that tree would be removed. As the root's would Destroy the brickwork very quickly.
Is the drainage pipe drained from the spouts of the house?
Man I wish your team was in my area for work
Very nice work. Did the slope of the hill prevent you from going out farther?
Thank you very much, the slope got pretty drastic after the wall. Moving it out 5 more feet would have more then doubled the cost of the project. Plus the customer didn't want to lose the tree if they didn't have too.
I was really curious to see what you guys were gonna do it the mystery drain but you edited it out.
Nice work! but you killed the tree. On top of that the tree will most likely fall on the power line during a windy day. It is never good to cut roots mostly that close. Most contractor never care about the trees, and the owner often are getting upset, mostly when this tree, provide shade or character to the house. before working around a tree, ask to an arborist first and not to your landscaper. But very nice work on the retaining wall!!
Good observation
Another big one is when that tree goes most likely it will tear up that retaining wall.
@@Luckingsworth they cup the roots so that should not affect much. Mostly if they feel up the hole proprely just after.
@Frfggg Ffgcdkkd not the main root, and certainly not that close to the main trunk.
I had to put down few trees in the past. And one of then was over 100 years old if not 200.
Every root fees on part of the tree. If you cut one you may see only one of the main branch dying. If you cut one of the big roots, they may not have enought, left for the tree to recover.
Wondering how much would it cost for this project ?
if u are not wrapping that pipe like a burrito with the rocks above and below then pinned together on top with a non woven fabric that system isnt going to last. the non woven material prevents dirt from getting under it so no dirt in the rocks and no dirt in the pipe. keeps it free and clear for decades of use.
I see you did three lifts for the base. Are those 8" lifts? So basically 2 feet before adding any block?
We do lifts in 3 inch increments. The base is about 8 inch after compaction. Thanks for watching and hope this helps
Good stuff buddy.
Glad you enjoyed it
How many centrifugal pound compactor is that ? Thanks. You do badass work!
Thank you very much, The compactor is a wacker 2540 and it's about 5600 lbs of centrifugal force.
That looked like a pretty big root you had to cut in two. Is there any risk that will kill the tree?
Unfortunately there wasn't any other option but its been a few years and the tree is still doing great
You guys don't do a thin layer of concrete under your first course?
What retaining wall blocks are you using on this wall?
These are Allan Block, they are one of the best blocks you can get for the price in my area.
