Incorporate Geogrid for Reinforcement and Drainage

PART 3: How to build a 2-tier retaining wall. #hardscape #retainingwall #howto
What happens here
As the lower retaining wall courses are laid and backfilled, ensure that layers of geogrid are incorporated at specified intervals. The geogrid extends into the backfill stone, creating a reinforced earth mass that enhances the wall's structural integrity and resistance to soil pressure. The goal is to bind the wall to the soil behind it, making it more stable. The clean backfill stone around the drainage pipe ensures that any water infiltrating the reinforced soil mass will flow effectively towards and into the drain pipe, preventing hydrostatic pressure buildup.
Goal: Reinforce the lower wall with geogrid and facilitate water drainage through the backfill stone to the drain pipe
