Double Terraced Retaining wall crashes down pt2

What happens here

This step focuses on establishing a robust and level foundation for the retaining wall. First, any reusable excavated topsoil is carefully separated and piled to the side. The bottom of the excavated trench is then meticulously leveled using a shovel, ensuring a consistent depth. A thin layer of 3/4 inch clear road gravel is spread across the trench floor. This gravel layer serves two purposes: providing initial stability and improving the traction for the compaction equipment. A NorthStar plate compactor is then used to thoroughly compact the gravel, ensuring maximum density and eliminating any potential for settling. For areas where the plate compactor cannot reach, such as tight corners or near the existing structure, a hand tamper is utilized for manual compaction, guaranteeing uniform solidity across the entire sub-base. Work gloves are used for hand protection.

Goal: Create a solid, level, and highly compacted sub-base for the retaining wall blocks.

the soil we want to reuse gets saved and set to the side in fact Blaine's gonna scoop away all of that loose material just to make sure nothing gets kicked into the bottom of our base before we have the wall phased out and towed in the new trench gets touched up by hand before it gets hit by machine alex scrapes a thin layer of rock into the bottom of the trench simply to get better traction with the packer [Music] Heka packs the sub-base material which is the Roger to make sure that if there was any like excavation over sizing it's all firmed up before the base actually goes in [Music] while the base is getting prepped for the new retaining wall the block is getting prepped to get thrown away with a full bucket he ops to back down the hill right off from the driveway if he went forward with it there'd be rock all over the yard [Music] with the sub-base material packed and ready to go he can now add enough material to bring it up to the bottom of his retaining wall but that still has to get past unlike class 5 or other materials that may be used as base this material does not need a lot of compaction to lock together in fact a light hit pretty much sets it in place the boys will add a
