Sloped yard? Wet basement after a hard rain? We grade the property, install retaining walls where the slope is fighting you, and route drainage away from the house.
Most retaining wall failures come from skipping the boring parts — drainage behind the wall, proper base depth, the right backfill. We don't skip the boring parts. Engineered systems for walls over 4 feet; segmental block systems for everything else.
