- All right, here we go again, another video.
So in this video, we're gonna show you how we go about
building the concrete retaining wall the right way.
From the looks of it, this one failed also due to drainage.
Hope everyone's doing well, stayin positive.
It's gonna be a fast paced video.
Some things to look out for, we're gonna be using our drone
for the first time.
Also, we're gonna show you an inside look
of our double mat rebar cage for our concrete footing.
And at the end, you got some behind-the-scenes footage.
Stick around and let's get into it.
So here we're putting up the final board for the side.
This wall is approximately 40 feet long by three feet high.
All our boards we'll be using are 2x12s.
Okay, as we move around to the front,
you may notice the four, 2x8 stakes.
We use these boys temporarily to add our first board
for the back wall.
Being a 2x8 is also allows us to establish our thickness
of the wall, which is eight inches.
Once we get the first board up,
we then place our 2x4 stakes,
approximately four to five feet on center
and continue building the back wall.
Surprised we was able to get the drone up
due to how close we were to the Oakland airport,
airport call sign, O A K for all my pilots out there.
As we get started it with the rebar,
got a lot of questions in the inbox from our last video
regarding why do we use the nails and tie wire
to hold a vertical rebar.
To check out that video you can click the link above
or in the description below.
Well, the main reason is our lead is OCD about his rebar.
Well, in all seriousness,
what this does is make sure our rebar does not shift
or move during the pour, which is very important.
Now that we've got our verticals up,
now, we'll be adding our horizontals.
All our rebars are either number four or number five
spaced at a minimum 12 inches on center
when it comes to our retaining walls.
Here, we're using our rebar tying gun to make quick work
of putting this together.
Most of our concrete footings are a minimum
of three to four feet wide and 18 inches thick.
Just like a waltz,
We also use either number four and number five rebar spaced
at 12 inches on center.
On this particular project we used about a half a ton
of number five rebar.
We also use our action cam to give you a true look
inside a double matt rebar cage.
Now that we've got the back, the rebar concrete footing
in place, it's time to close up the wall.
You have a 2x4 stake spaced
approximately four to five feet on center.
Use this piece of scrap wood to be sure
to have our true eight inches,
which is the thickness of the wall.
After we placed each board, we add a wall tie
spaced approximately 16 inches on center.
We can pretty much eyeball this.
Don't need a hammer anymore for the most part.
We use duplex nailer to make quick work
of closing up the front.

If you take a close look,
here the wall ties are held together with wedges.
This will prevent the wall from opening up when we pour.
Be sure to check out our retaining playlist
in the above link or in the discussion below.
While you're down there, be sure to subscribe
and like the video.
With this drones shot, you'll get a clear picture
of how we place our stakes.
Each stake gets approximately five feet tall,
four to five feet on center.
Okay, now that we've got the wall closed up,
it's time for some concrete.
So be sure to subscribe to our channel.
You'll be the first one to see it when we pour it.
Also check out these behind-the-scene photos,
you can get true sense of what it takes
to put a retaining wall together the right way.
