What Is French Drain Installation in Roanoke, VA?
In Roanoke, French drains move groundwater away from your home. We bury a pipe with holes in it inside a gravel trench. This stops basement flooding from clay soil that stays wet too long. When rain from Mill Mountain flows toward your house, French drains send the water somewhere else before it pushes on your foundation walls. We connect these drains to sump pumps or pipes that let water out across Roanoke Valley neighborhoods.
We can check your property the same week you call. We make custom plans for homes on Mill Mountain slopes where water runs downhill. Our systems keep finished basements in Garden City dry all year.

French Drains Protect Foundations From Water Damage
French drains stop foundation problems by moving water away before it reaches your basement walls. We dig a trench 18 to 24 inches deep along your foundation. The trench slopes down toward where the water goes out. We line the trench with special fabric that stops clay soil from blocking the holes in the pipe. We put in a 4-inch pipe with holes in it. We pack ¾-inch washed gravel around the pipe. The drain connects to a pipe that lets water out or to a sump pump. We fill the dirt back in and fix your yard at Roanoke homes.

Interior vs Exterior French Drain Systems for Roanoke Basements
Outside French drains catch groundwater before it touches your foundation. Inside systems catch water that already got through your basement walls.

Inside systems install faster in finished basements. You don’t have to mess up your landscaping. Sump pumps are required for inside drains in low-lying Garden City homes.
Old Southwest homeowners with finished basements often can’t dig outside. Big trees near foundations get in the way. Inside drains help right away while you plan outside work during dry months. Inside systems catch water at the basement floor and pump it outside. The best way is to pump water 10 feet or more from your foundation so it doesn’t come back. We check your home’s drainage needs.

But Roanoke waterproofing companies install French drains all year when basement flooding is a problem. Frozen ground makes the work harder but doesn’t stop emergency jobs.

We do winter emergency work for homes with active foundation leaks in South Roanoke.
Grandin Village homeowners who plan basement remodels need dry conditions all year. Getting drains installed early stops emergency calls during Blue Ridge Mountain storms.

Check surface grates every three months for leaves blocking the water inlet. Use a garden hose once a year to flush out dirt from the pipe holes.
