What happens here

Lay a base layer of angular gravel in the wider footing trench. This gravel acts as a drainage layer and provides a stable, level surface for the first course of blocks and geo-grid. Use a plate compactor, such as a Wacker Neuson, to thoroughly compact the gravel layer, ensuring a solid foundation. While this is being done, wet down the dry soil with a garden hose to facilitate better compaction, as dry soil is difficult to compact properly.

Goal: Create a compacted, level gravel base for the retaining wall

Tools and materials

  • Angular Gravel N/A — Creating the base layer of the footing
  • Garden Hose N/A — Wetting down dry soil for better compaction
  • Plate Compactor Wacker Neuson — Compacting the gravel base
  • Shovel N/A — Spreading gravel evenly
  • Skid Steer Loader — Transporting and dumping gravel into the trench

um and with that you know the soil is really really dry we're getting a whole lot of dust and then when it's when the soil's like this dry you know you can't really quite get the you can't really get it good compaction on it so Jo going down and kind of just wetting everything down a little bit that's uh kind of the same thing that we do oh there's bla kind of the same thing we do with the uh recycle class 5 now if you watch you'll see that the guys are careful to step over the block but not on it that main course of block that's down still could have deflection if you put too much pressure on any one point it's not until the second course of block is down pinned and locked in place can you start to walk on the actual retaining wall because now you're Distributing the weight over a larger surface area instead of having pinpoint pressure on any one point on the base [Music] course all right now let's go a little simpler here do you see that black material laid out horizontally behind the retaining wall that's what geog grid is it kind of reminds me of orange snow fence but it's not and it can't be substituted and it can't be laid any just which way it's got One Direction where its sheer strength actually functions if you lay geogrid out the wrong way it's like not having any geogrid in at all because it's not actually holding the wall the correct way
