Common French Drain Service Questions

French drains and footing drains are virtually identical, except that French drains sit a foot or two beneath the ground, and footing drains sit as deep as your foundation footings go, sometimes up to 10 feet. Both drainage systems collect water before it reaches the soil around your foundation and divert it to a safe place on your property for disposal.

You should always cover a French drain with gravel rather than dirt. Gravel will let water seep into the drain more easily, which means the drainpipe will collect more water and divert it away from your foundation. Dirt over a French drain will also clog the pores in the drainpipe over time, rendering your drainage system useless until you excavate the line and clear it, a time-consuming and potentially expensive process.

A French drain should be 4 to 6 feet away from your foundation in most cases. However, the right distance for your home depends on the landscape and how bad your water problem is. Ask a foundation drain installation professional near you for advice on your exact situation.

You need gravel underneath a French drain pipe so that it allows the water to seep through the ground and be taken away from the slope of the drain. You should use river rock or granite chips in your French drain installation to accommodate maximum drainage and prevent clogging in the system.

When installing a French drain, the holes in your pipe go down. This allows water to flow from the gravel below into the pipe to be carried away from your flood-prone area. If you’re using a corrugated pipe with slots on all sides, it doesn’t matter which direction the pipe is facing.
