What happens here

Before beginning the layering process, ensure the construction site has a properly prepared and stable base. This often involves excavating to the required depth, establishing a level foundation, and potentially compacting the native soil or a sub-base layer. Once the base is ready, unroll the first layer of geogrid over the prepared area. Position the geogrid so it extends from the face of the planned structure (e.g., behind a retaining wall block line) into the area where the aggregate will be placed, ensuring it is taut and free of any major wrinkles or folds.

Goal: Establish a stable foundation and initial reinforcement layer

Tools and materials

  • Plate Compactor — Compacting the native soil or sub-base layer
  • Rake — Spreading and leveling the base material
  • Shovel — Excavating and leveling the base layer
  • Geogrid — Providing tensile reinforcement to the soil
