A drain tile system, also known as a perimeter drain or footing drain, is a type of drainage system installed around the perimeter of a building's foundation to prevent water from seeping into the basement or crawl space.
The system typically consists of a perforated pipe that is installed in a bed of gravel or other porous material around the foundation's perimeter. This pipe is then connected to a sump pump or other drainage system that carries the water away from the building.
The purpose of a drain tile system is to prevent water from building up around the foundation and causing damage to the building's structure. By directing water away from the foundation, the system can help prevent basement flooding, mold growth, and other water-related problems.
Drain tile systems are commonly installed in new construction but can be retrofitted into existing buildings.
