Mapei Mapedrain 35 4’ x 50’ roll

DESCRIPTION Mapedrain 35 is a high-strength, three-dimensional drainage composite. It consists of a woven filter fabric bonded to individual dimples of a molded polypropylene core, minimizing fabric intrusion into the drainage channels 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 35’s woven, monofilament fabric withstands high abrasion from applied overburden and prevents intrusion into the drainage core due to its low elongation characteristics. As such, the woven fabric is better suited to receive direct poured concrete than nonwoven geotextile fabrics. Mapedrain 35 also has a polymeric protective film on the back side to provide additional protection to waterproofing membranes. FEATURES AND BENEFITS ▪ Lightweight and easy to install, Mapedrain 35 provides cost savings and eliminates the need for aggregate backfill. ▪ Mapedrain 35 also serves as a protection course for MAPEI waterproofing membranes. Contact a MAPEI representative for specific guidelines. ▪ Mapedrain 35 high-flow drainage provides up to three times the flow capacity of aggregate or sand. ▪ Mapedrain 35’s high compression strength withstands overburden pressure. ▪ Mapedrain 35 channels water away from installed waterproofing systems. ▪ Native soils, gravel or concrete can be used over Mapedrain 35. ▪ Geotextile filter fabric ensures no-clog drainage by preventing intrusion of soil, concrete or construction grout into the flow channels. ▪ Unaffected by permanent immersion in water, bacteria, dilute acids and alkalis, Mapedrain 35 will not deteriorate when exposed to these conditions. ▪ Mapedrain 35 offers relief of hydrostatic pressure when connected to a passive gravity drain or operational sump pump.
