Retaining Wall Drainage

Proper drainage is critical to retaining wall longevity. Without adequate drainage behind the wall, hydrostatic pressure builds up and can cause even well-built walls to fail. Clear Flow installs drainage aggregate and perforated pipe behind all retaining walls to ensure water drains away from the wall, not against it.
