Why Waterproofing Matters in White City
The PNW receives more sustained rainfall than nearly any other US region. Soil stays saturated for 6+ months a year, and hydrostatic pressure pushes groundwater into crawl spaces continuously rather than during storm events. Without interior drainage and an actively-running sump pump, water migrates in through the substrate even when it is not raining. Drainage is not optional — it is core infrastructure.
What a White City Waterproofing System Should Include
- ✓Interior perimeter drain (high-capacity, 2-inch+ radius)
- ✓Heavy-duty sump pump (1/2 HP minimum, battery backup)
- ✓Daylighted discharge line (PNW soils do not absorb runoff well)
- ✓20-mil reinforced vapor barrier over drainage
- ✓Exterior French drain on uphill side if applicable
- ✓Anti-microbial wood treatment on Douglas fir framing
Interior vs Exterior Drainage in Oregon
Recommendation
Interior is mandatory. Exterior alone fails because soil saturation defeats it within 3–5 years. PNW interior drains run nearly year-round — specify higher-capacity components (2-inch+ vs 1.5-inch elsewhere).
Sump Pump Sizing
A 1/2 HP unit is the minimum; many homes need 3/4 HP. PNW sump pumps run 200–400 cycles per month in winter — they wear out fast. Plan for 5–7 year replacement cycles. Battery backup essential.
What to Watch For in Oregon
- !Reject any quote without battery backup — PNW power outages average 6–12 hours, and pumps that stop = floods
- !Confirm the sump pump is rated for continuous-cycling duty (many residential pumps are not)
- !Check for existing wood rot before waterproofing — sealing in active rot accelerates damage

Wood rot prevention is the dominant ROI driver. One sill plate replacement runs $8K–$25K — waterproofing typically pays for itself by avoiding one such repair. Resale value: PNW buyers explicitly look for sump-pumped, drained crawl spaces and discount homes without them.
