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.

Lightweight and easy to install
Provides cost savings and eliminates the need for aggregate backfill
High-flow drainage provides up to three times the flow capacity of aggregate or sand
Channels water away from installed waterproofing systems
