Relieve Water Pressure Behind Retaining Walls
Retaining wall drainage is the pressure-relief system that keeps wall structures functional. Without proper drainage, even strong wall materials can fail under repeated wet-season loading.
Core Drainage Elements Behind Retaining Walls
- Collection zone: Free-draining backfill and aggregate layers.
- Conveyance path: Perforated drain lines at the correct elevation and slope.
- Relief outlets: Safe discharge points that prevent back-pressure build-up.
- Surface diversion: Keep roof and hardscape runoff from feeding the wall backfill.
Why Boise Sites Need Careful Wall Drainage
Clay-heavy soils and seasonal moisture swings create long-duration saturation behind wall systems. Where slope is present, added runoff velocity can quickly overload weak drainage layouts.
We commonly integrate wall drainage with catch basins, surface interception, and erosion control for complete slope management.
Inspection and Correction Process
- Wall condition survey: Document movement, cracking, and seepage profile.
- Drainage path verification: Confirm line location, slope, and discharge viability.
- Relief enhancement: Improve collection and outflow to reduce pressure cycles.
- Stability pairing: Coordinate with retaining wall stabilization where structural movement exists.
