Waterproofing and Drainage

Crawl Space French Drains

When water comes from the yard, a French drain can catch it first. A trench with perforated pipe, gravel and filter fabric carries water around or away from the house. We plan the route and the outlet so it works for the long term, and we pair it with interior drainage where needed.

Questions

Common questions

Will it tear up my yard?

It needs a trench, and we restore the area. We plan the route to limit impact.

Where does the water go?

To a safe outlet, or to a pump if there is no daylight.

Do I still need a sump?

Often yes, as a backup. We explain the combination.
