Water moving through a slope
When rain soaks into a hillside, gravity pulls it downhill through the soil until it meets something — like a foundation wall. That's why the uphill side of many Camas crawl spaces is wetter than the rest. On newer lots, settling backfill around the foundation can make it worse in the first few wet seasons.
A Camas waterproofing plan
- Interior drain pipe along the uphill wall
- Gravity discharge downhill where possible, or a sump
- Repairs where concrete is letting water in
- Outside recommendations: gutters, downspouts, regrading on the uphill side
- A new vapor barrier or encapsulation afterward
Near the water
Homes on lower ground near Lacamas Lake or the Washougal River may see water rise from below instead. The fix is similar — drainage to a collection point — but laid out differently.
What shapes the scope in Camas
- Uphill seepage vs. rising water on lower ground
- Drainage length along the uphill wall
- Gravity outlet availability on the slope
- Foundation repairs
- Outside grading and gutter changes
Newer homes with footing drains
Many newer Camas homes were built with exterior footing drains. If water still reaches the crawl space, those drains may be clogged, disconnected or overwhelmed. Interior drainage can work alongside them. Builder documentation, if you have it, helps us understand what's already in the ground.
Questions from Camas homeowners
Why does water come in on one side of my Camas home?
Usually the uphill side. We'll confirm.
Can a sloped lot drain by gravity?
Often, yes, if there's a safe downhill outlet.
