Retaining Wall & Slope Drainage questions from Temecula customers

Why do retaining walls fail?
Most often from water, not weight. With no drainage behind it, a wall holds back saturated soil and water pressure builds against the face — the weeping, bulging and staining that precede failure. Relieving that pressure is what back-of-wall drainage does.
What drainage does a retaining wall need?
Typically gravel backfill and a perforated collector pipe behind the wall that carries water to an outlet, plus weep points through the face. The point is to give water a path out before it can load the wall.
How is hillside runoff handled on a sloped lot?
By intercepting it above the area being protected — an interceptor drain or swale near the top of the slope — so water is caught and carried off before it reaches the house or the wall below. Catching it high beats collecting it low.
The slope behind my house sends water down in every storm — what can be done?
The runoff is intercepted above the slope and routed to an outlet, and any wall at the toe is drained rather than relied on to hold it back. Slope water is a top-down problem, so the fix starts at the top of the run, not at the house.
