Subsequent Courses and Backfilling

What happens here

Subsequent courses of retaining wall blocks are stacked on top of the previous layer, interlocking with pins or lips on the blocks. Each course is leveled and aligned carefully. After every 1-2 courses (or as per design), the area behind the wall is backfilled with gravel around the perforated pipe and then with suitable soil. Compaction of the backfill is essential to prevent future settling and ensure proper drainage. Geogrid layers are incorporated at specified intervals (e.g., every 2-3 courses) to strengthen the soil mass and enhance the wall's stability.

Goal: Following the first course, additional courses of retaining wall blocks are stacked, leveled, and backfilled with gravel and soil, incorporating geogrid as specified.
