Mapedrain 50

Extra High-Strength, High-Flow, Pre-Fabricated Drainage Composite

Mapedrain 50 is an extra 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 50’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.

Lightweight and easy to install, Mapedrain 50 provides cost savings and eliminates the need for aggregate backfill.
Mapedrain 50 also serves as a protection course for MAPEI waterproofing membranes.
Mapedrain 50 high-flow drainage provides up to three times the flow capacity of aggregate or sand.
Mapedrain 50's extra high compression strength withstands overburden pressure of automobiles, tractor trailers and fire trucks.
Mapedrain 50 channels water away from installed waterproofing systems.
Native soils, gravel or concrete can be used over Mapedrain 50.
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 50 will not deteriorate when exposed to these conditions.
Mapedrain 50 offers relief of hydrostatic pressure when connected to a passive gravity drain or operational sump pump.
This product is specifically designed for projects demanding the highest compressive strength.
The efficiency-oriented volume packaging of Mapedrain 50 allows 7 rolls per pallet.
The drain core is 40% post-industrial recycled polypropylene material.
