Interior Drainage Systems
An interior drain is a perforated pipe set in gravel along the footing that catches water from the wall and the floor and carries it to the sump. Covered by a barrier, it keeps the floor dry without digging up your yard, and it is a core part of a lasting waterproofing system.

Common questions

Does it need a pump?
It leads to a sump where a pump moves the water out.
