Tigard, Oregon
Waterproofing for Tigard basements and crawl spaces
Waterproofing means keeping rain and ground water out of the space under your house. If the basement floor is wet after a storm, or the crawl space smells of damp soil, call the number below and speak with an independent local waterproofing company that works in Tigard.
Tigard Waterproofing is a referral service, not a contractor. The company you speak with gives its own price and its own dates.

Which house is yours?
A basement and a crawl space leak in different ways
The fix depends on which one you are standing over.
If you have a basement
Water usually shows where the wall meets the floor, at a crack, or around a pipe. A single path can often be closed on its own. Water along a whole wall needs a drain.
- Basement waterproofing: interior drains and wall liners
- Exterior waterproofing: stopping it outside the wall
- Basement leak repair: one crack, one pipe, one window well
- Wet basement: damp with no obvious leak
If you have a crawl space
You may never see the water. You smell it upstairs, or the floor feels soft, or the insulation is hanging down when you open the hatch.
- Crawl space encapsulation: a sealed liner and dry air
- Crawl space repair: standing water, fallen insulation, damp wood
- Sump pump installation: for water that collects after rain
- Yard drainage: when the lawn sends water under the house

- A musty smell on the ground floorDamp air from bare soil under the house is drifting up through the floor.Encapsulation
- A pump that never seems to restThe pit is filling as fast as it empties, or a stuck switch or failed valve is sending water back.Sump pumps
- A lawn that stays under water by the houseThe ground slopes the wrong way or has nowhere to drain, so the foundation sits in a pond.Yard drainage

Local ground rules
Three things to know before work starts in Tigard
The Tigard guide to drains, flood maps and 811 has the details, and the numbers to call when a street drain backs up.
Check the flood map
Look up your address on FEMA's Flood Map Service Center. Water from a creek and water from the soil call for different work.
Know which drain is yours
The grate in the street is public. A drain or pipe on your own lot is yours to keep working, and that includes one a company puts in.
811 comes before any digging
Buried lines must be marked before a trench is opened. Oregon asks for the request two business days ahead.
