A French drain — also called an interior perimeter drain or weeping tile — is a gravel-filled trench system installed along the perimeter of your basement floor. It intercepts water as it seeps through foundation walls or up through the floor and channels it to a sump pit, where it's pumped safely out of your home.
Unlike exterior excavation waterproofing, interior French drains are installed from inside your basement — making them faster, less disruptive, and significantly more affordable while still solving chronic water problems permanently.
How We Install French Drains
Perimeter Trench Excavation
We jackhammer a narrow trench along the inside perimeter of your basement floor at the base of the foundation wall.
Drain Pipe & Gravel Bed
A perforated pipe is laid in the trench over a gravel bed, allowing water to enter and flow freely toward the sump pit.
Wall Flange Installation
A drainage flange is installed against the wall to capture water that weeps through block or poured concrete walls before it ever hits your floor.
Sump Pit Connection
The drain pipe slopes toward a sump pit where a pump automatically removes the water from your home.
Concrete Restoration
We pour new concrete over the trench, restoring your basement floor to a clean, finished appearance.
French Drain FAQs
How long does French drain installation take?
Most installations are completed in 1–2 days. We work quickly and clean up thoroughly before leaving.
Will it smell or create a mess?
Cutting concrete creates dust, which we manage with containment. The finished result is clean and odor-free.
Does a French drain require a sump pump?
Yes — the drain routes water to a sump pit, and a pump removes it. We install both as a complete system.
How long does it last?
A properly installed French drain system lasts for decades. We stand behind our work with a warranty.
