Why Waterproofing Matters in Evanston
Mountain West waterproofing is concentrated around the spring melt season — a 6–10 week window when frozen ground releases months of stored snow. Foundations face heavy water pressure during this window even though the climate is otherwise dry. Rocky soils and high altitude make exterior trench drains expensive, so interior systems are usually the right choice. Pair with radon mitigation (Mountain West has elevated levels).
What a Evanston Waterproofing System Should Include
- ✓Interior perimeter drain (rocky-soil tolerant)
- ✓Sump pump with battery backup (mountain power outages common)
- ✓Insulated discharge line (avoids freeze-shut in early-spring nights)
- ✓12–20 mil vapor barrier (radon-rated if Zone 1)
- ✓Exterior swale or French drain if grading allows
- ✓Pipe insulation throughout
Interior vs Exterior Drainage in Wyoming
Recommendation
Interior systems dominate in the Mountain West because rocky soils make exterior trenching expensive and unreliable. Interior drains can be installed in nearly any soil condition.
Sump Pump Sizing
A 1/3 to 1/2 HP cold-weather-rated pump is standard. Mountain power outages are routine — battery backup essential. The pump typically runs hard for 6–10 weeks in spring then idle for 8 months — pick a model that handles seasonal duty cycling.
What to Watch For in Wyoming
- !Test radon before waterproofing — Mountain West elevations have elevated radon levels
- !Confirm pump and discharge are rated for sub-freezing operation — this matters in early spring
- !Verify the exterior grading addresses snow-shed patterns from the roof, not just rain runoff
