Necessary steps if you don’t want your wall to fall over.
What happens here
Begin by laying out the geo-grid reinforcement. The video shows a worker placing a geo-grid layer directly on top of a completed course of retaining wall blocks. The geo-grid, a black mesh material, is unrolled to extend horizontally from the back of the retaining wall blocks into the excavated backfill area. The narrator emphasizes that this is typically the second layer (implying a previous layer is already embedded deeper in the wall), and its purpose is to be 'sandwiched between courses' to hold the wall securely in place.
Goal: Provide horizontal tensile reinforcement to the retaining wall structure.
Tools and materials
- Geo-grid — Providing structural reinforcement to the retaining wall by creating tensile strength within the soil mass
- Retaining Wall Blocks — Constructing the primary structure of the retaining wall and providing a surface for the geo-grid placement
- Utility Knife — Cutting the geo-grid to the appropriate length
