the pea gravel as foundation and backfill stone kills me

What happens here

This video provides a detailed analysis of a failed retaining wall that collapsed just five months after construction. It highlights critical errors in its initial installation, such as the absence of geogrid reinforcement, lack of separation fabric between soil and base stone, and the incorrect use of pea gravel for drainage backfill instead of proper 3/4 inch limestone. The project outlines how to identify these common flaws when diagnosing retaining wall failures.
