Water and Drainage
Crawl Space Waterproofing
If water enters your crawl space as liquid, vapor barriers alone will not fix it. We find where the water comes from and combine grading, interior drainage, wall sealing and pumping to move it away, then dry and protect the space.

Questions
About crawl space waterproofing
Will a liner alone stop water?
A liner stops vapor from the soil, but it cannot hold back flowing water. Drainage and a pump handle liquid water, and the liner finishes the job.
How do you know where the water comes from?
By looking at the slope, gutters, walls, soil and timing of the water. We often find that fixing roof runoff solves a large share of the problem.
