Question 1

What is a foundation drain?

Accepted Answer

A foundation drain (often called a French drain) is a system installed around the foundations of a building. It captures and evacuates accumulated water in the soil to reduce hydrostatic pressure on the foundation walls.

Question 2

When should a foundation drain be redone?

Accepted Answer

It is recommended to check or replace a foundation drain if your house is over 25-30 years old, if you observe water infiltration or humidity odors, if cracks appear on the foundation walls, if the existing drain is made of terracotta or concrete, or if the system does not comply with current standards.
