The right fix starts with the right diagnosis

Relieve hydrostatic pressure with a French drain

When clay soil around a DMV foundation stays saturated, it pushes hydrostatic pressure against basement walls and footings. A French drain is a gravel-filled trench with perforated pipe that gives that water a lower-resistance path to travel, away from your foundation instead of through it.

Common problems we solve

  • Water pooling near the foundation after rain instead of draining away
  • Basement or crawl space walls under visible hydrostatic pressure
  • Yard grading that channels runoff toward the house
  • Repeated wet spots in the same area of the yard every storm

Benefits of a properly designed solution

Relieves pressure at the source

Diverting subsurface water reduces the hydrostatic load pushing against foundation walls.

Works with your landscaping

Trenches can be routed around existing beds, walkways, and grading.

Reduces long-term foundation stress

Less standing water against the foundation means less risk of cracking or wall movement over time.

Pairs with interior systems

An exterior French drain reduces the water interior drainage and a sump pump have to handle.

Our four-step process

  1. Inspect: Document moisture, drainage, structure, and site conditions.
  2. Explain: Review findings with photos and straightforward priorities.
  3. Install: Complete the agreed scope with careful home protection.
  4. Verify: Test components, clean the work area, and complete a walkthrough.
Common questions

French Drain Installation FAQs

Is a French drain the same as interior drainage?+

No. A French drain is installed outside, in the yard or along the foundation perimeter, to intercept water before it reaches the wall. Interior drainage is installed inside a basement or crawl space to catch what still gets through.

Will a French drain stop all foundation seepage?+

It significantly reduces the water reaching your foundation, but severe cases often pair an exterior French drain with interior drainage and a sump pump for complete protection.

How deep does a French drain need to be?+

Depth depends on your foundation footing and the source of the water, typically determined during the inspection based on where the saturation actually sits.
