Final Drainage Layer and Geotextile Fabric

What happens here

A geotextile fabric is carefully unrolled and laid along the base of the retaining wall, acting as a permeable barrier to prevent soil migration while allowing water to pass through. Following the fabric installation, a substantial layer of pebbles (river rock) is spread over the geotextile fabric, creating a robust drainage layer. This stone layer helps manage water runoff behind the wall, preventing hydrostatic pressure buildup and enhancing the long-term stability of the structure. Workers use shovels and rakes to evenly distribute the pebbles, ensuring full coverage and proper drainage function.
