01Planning and Preparation

  • Determine the location and size of your retaining wall. Measure the length and height of the wall.
  • Check with your local building codes and obtain any necessary permits.
  • Gather the tools and materials needed, including blocks, gravel, geogrid, adhesive, and a shovel.
  • Mark the layout of the wall using stakes and string.

02Excavation

  • Dig a trench along the marked layout of the wall. The trench should be wide enough to accommodate the blocks and deep enough for stability.
  • Create a level base by removing any rocks or debris. Compact the soil using a tamper.
  • Add a layer of gravel for drainage and stability. Compact the gravel.
  • Check the level and adjust as necessary.

03Building the Wall

  • Begin laying the first course of blocks along the trench. Use a level to ensure they are straight and level.
  • Apply adhesive between each block to secure them in place.
  • Continue adding courses of blocks, making sure to stagger the joints for stability.
  • Cut any blocks as needed using a saw or chisel.
  • Backfill the area behind the wall with gravel or soil as you go.

04Installing Geogrid

  • After a few courses of blocks, install geogrid for added stability.
  • Place the geogrid vertically behind the blocks, extending it into the backfilled area.
  • Secure the geogrid to the blocks using adhesive or connectors.
  • Backfill the area behind the geogrid with gravel or soil.

05Finishing Touches

  • Complete the wall by adding the final courses of blocks.
  • Ensure all blocks are securely in place and level.
  • Clean up any excess adhesive or debris.
  • Add finishing touches such as cap blocks or decorative stones.
  • Step back and admire your newly built retaining wall.
