Analyze Common Retaining Wall Failures

What happens here

Examine a visibly failing retaining wall to understand common construction errors. The main issue highlighted is the incorrect use of filter fabric placed vertically behind the wall face. This vertical fabric traps dirt and water, preventing proper drainage and leading to hydrostatic pressure buildup, ultimately causing the wall to bulge and fail. Correct practice involves allowing water to flow freely through the wall's drainage zone.

Goal: Identify and understand incorrect construction practices that lead to retaining wall failure.
