Check for Geogrid and Separation Fabric

What happens here

Inspect the exposed areas behind the failed wall sections for the presence of geogrid reinforcement and separation fabric. The speaker explicitly states that "There was no geogrid. There was no fabric to separate the soil from the basestone." Geogrid is a vital synthetic mesh used to stabilize the soil behind the wall, preventing it from pushing forward. Separation fabric (geotextile) is essential to prevent the backfill material from mixing with the surrounding soil, maintaining drainage efficiency.

Goal: Verify the presence or absence of crucial reinforcement and separation materials.
