How a working drainage system protects a home

Rain runs off the roof, into the leaders, down through drain rock to the perimeter drain, then out to the storm connection or sump — keeping water off the foundation wall.

Drain Tile Replacement — quick answer

When the original tile is clay, concrete, or has failed in multiple locations, replacing the full perimeter is usually cheaper over the life of the house than repeated spot repairs. It is also the opportunity to waterproof the foundation wall while it is exposed.
