Mapedrain TD Drainage Composite
High-Strength, High-Flow Drainage Composite for Foundations
Mapedrain TD Drainage Composite is a high-strength, three-dimensional modular drainage and collection composite for foundations. It consists of a nonwoven filter fabric that is bonded to and wrapped around a molded polypropylene core, minimizing fabric intrusion into the drainage channels that can be caused by overburden pressure. The filter fabric allows water to pass freely into the drainage core, which provides hydrostatic relief while preventing the passage of soil or sand particles that might clog the core. Mapedrain TD Drainage Composite is designed to replace a conventional gravel covered pipe drain.
