What happens here

Establish the retaining wall by carefully laying the first courses of blocks on a prepared gravel base, ensuring proper alignment and stability. Utilize specialized blocks, including 'split half blocks' for corner detailing, which provide a rough, aesthetically pleasing face. Employ a gas-powered concrete saw (Husqvarna K770) to precisely cut blocks for drain tile placement, creating custom slots that secure the drain tile within the wall structure. Implement geo-grid reinforcement behind the wall, layering it with gravel and compacted soil. The importance of compacting each layer of backfill with a plate compactor (Tomahawk or Wacker) is emphasized to prevent future settling, which can compromise the wall's integrity. Throughout this process, the excavator (Daewoo) and skid steer (Volvo) continue to manage and deliver materials efficiently.

Goal: This step details the construction of the retaining wall's foundational layers, involving the precise placement of blocks and strategic backfilling with granular material and soil.

all right we are done for the day uh so plan for tomorrow it's gonna keep basing in blocks along here while one person is doing that the rest of us are just gonna be following behind building and backfilling more of the same hey guys tonight's drink of choice is coconut waterloo drink it if you don't like yourself because it's not very good i love coconut water and i like grape waterloo which does not taste like cough syrup somebody told me um when i said i love grape waterloo they're like it tastes like cops or if you're selling out and i'm like no i'm not i love that stuff and i love coconut this no no bad bad hey look at the soil that we're using behind the wall right here you can see the clear difference so we've actually tarped separated and as we're digging the new wall you'll see we're separating the soil so we're literally looking at each scoop and going good bad and that's basically determined on how much water content is in it how much organic material is isn't it if we're getting gray green clay in it or if we're really what we're looking for is that nice brown even consistent dirt and this is what i mean it takes a lot of time on these retaining walls because we're trying to conserve the backfill trying to reuse it you'll see us hauling load after load after mode out of this site i mean and it's all extras to our customers so we're trying to keep it down within as reasonable amount as possible all right guys you're gonna have to excuse my language on this but like our day just went down that's a freaking mess up in there so we're gonna take that back one off next and uh have a look-see these look fine over here but we're gonna find out and we're gonna do it together guys all right guys what we got we lucked out we were able to get a hose that big old dog right there so we're going to throw it in real quick and tim's on his way to get a whole bunch of hydraulic fluid and we will get this store do that one of the guys on the last video asked me hey how to stand how do you like that debu you've owned it for a few years now what do you think of it and i think i commented this was before this happened it leaks a lot and it's underpowered other than that it's a great machine [Music] the reason we use the daewoo so much though because we have a kobelco excavator and those are great machines those are great machines those are the ones we've got we've got the 160 model and so we've got a smaller frame on it we've got a larger undercarriage smaller body…
