What happens here

To ensure maximum stability and prevent future movement, layers of geogrid are strategically incorporated into the retaining wall construction. As shown, geogrid is placed between every two rows of interlocking concrete blocks, creating a 'geogrid sandwich'. This mesh-like material extends from the blocks into the backfill area behind the wall. The backfill, consisting of crushed stone, is then compacted over the geogrid, effectively locking the blocks in place and distributing lateral forces, making the wall incredibly secure, even if it might be considered 'overkill' by some, it guarantees longevity.

Goal: Reinforce the retaining walls with geogrid for superior structural integrity and stability.

Tools and materials

  • Plate Compactor Wacker Neuson — Compacting the stone backfill over the geogrid layers
  • Utility Knife — Cutting the geogrid to size
  • Construction Adhesive — Securing the concrete blocks together for added stability
  • Crushed Stone Backfill — Filling behind the retaining wall and compacting over the geogrid
  • Geogrid — Reinforcing the retaining wall structure and preventing movement
