Basement Waterproofing in Salem: local conditions

Salem, OR sits on clay and silt in the Willamette Valley and has a wet marine climate with about 36–45" of rain a year in the valley. The local water table is high through the wet season, with mild winter freeze–thaw cycling, and basements and daylight basements are common on slopes. In practical terms, months of steady rain and high water tables keep basements and crawl spaces damp — which is exactly why basement waterproofing is a common need here.
