Retaining wall drainage and waterproofing in Surrey, BC
In Surrey's climate, drainage is the wall. We see walls that look perfect on the outside fail in 10 years because nobody put a drainage chimney behind them. Whether we're building new or upgrading the drainage on an existing wall, this is the work that determines how long your wall lasts.
// Surrey, BC
The hidden half of every wall. Done right, it's why your wall lasts 50 years instead of 15.

- Perforated drain pipe sized for the wall length
- Drain pipe daylighted to a safe discharge point

When you need this
A few situations where this is usually the right call.
You're building a new wall, period
Every retaining wall in Surrey needs drainage. We don't build walls without it. That's not negotiable.
Your existing wall is wet, mossy, or efflorescing
Salt streaks and white powder on the face mean water is moving through the wall. Drainage is failing.
You're seeing pooling water behind the wall
Standing water means hydrostatic pressure. That pressure is what pushes walls over.

Questions about drainage.
Water is moving through the wall, which means the drainage layer behind it is failing or was never built right. You'll often see white salt streaks (efflorescence) or moss growing on the face. The fix is to excavate behind the wall, install a proper drainage chimney with clear crush and a drain pipe, and daylight that pipe to a safe discharge point.
