Why Your Gutters Might Be Failing Your Foundation.
It sounds like a fix: Put up gutters, catch the rain, keep the walls dry. But in reality, the gutter is only 20% of the equation. If you don't have a plan for the "Discharge," you’ve just created a high-pressure water delivery system for your foundation.
If your downspouts end at the base of your home, you are effectively dumping a swimming pool's worth of water into the five feet of soil surrounding your footings.
The Consequences:
The Moat Effect:Â Clay soil (common in the South Bay) holds water like a bucket. That saturated soil expands and puts massive pressure on your concrete.
Capillary Action:Â Water doesn't need a crack to get in; it can move through the pores of the concrete via "wicking."
The Solution: We advocate for Hard-Piped Drainage. Every downspout should connect to an underground PVC line that carries the water to a safe discharge point well away from the house.
I’d rather have a house with no gutters and perfect grading than the most expensive gutters that dump water right at the corners.
