Western Washington soil swells when it is saturated and pushes on whatever is holding it back. That pressure is what opens foundation cracks, bows basement walls, floods crawl spaces and rots the framing above them. Repairing the concrete while the water keeps arriving is how homeowners end up paying for the same job twice. We assess the roof drainage, the grade, the footing drain and the structure as one system, because on your house they are one system.
