Frequently Asked Questions

Can a French Drain Go Under Concrete?

Yes, a French drain can go under concrete. However, if the concrete is a thin slab or the drain pipe has been placed on top of the slab then it will not be able to run all the way through.

A French drain is typically installed by drilling holes in the ground and running a flexible PVC pipe into them. The drainage pipe would then be attached to an underground storm sewer or another water source that would feed into your home’s plumbing system.

Why Do French Drains Fail?

The most common reason for French drains to fail is that the drain’s soil is not compacted or allowed to dry out. The draining water creates pressure on the sides of the pipe and causes it to break, which can be a costly repair.

A second reason why a French drain can fail is that there are obstructions in the way of water flow, such as tree roots or other objects.

If you’re wondering how your french drain has failed, give us a call, and we’ll help you get back up and running!
