CCW MiraDRAIN 6200 is a high-strength drainage composite made up of a durable, nonwoven fi lter fabric that is bonded to the individual dimples of a molded polypropylene core to minimize fabric intrusion into fl ow channels due to backfi ll pressure. The fi lter fabric prevents the passage of soil particles into the core while allowing water to pass freely. This product features a polymeric sheet adhered to the back of the core to prevent it from die-cutting the waterproofi ng membrane.Designed for use in high-fl ow, high-compressive strength, vertical drainage applications where single-sided subsurface drainage is needed, MiraDRAIN 6200 can also be used as a protection course over CCW waterproofi ng membranes when added protection is desired.The fl at side of MiraDRAIN 6200 fi ts snugly against wall surfaces, making this product ideal for foundation walls, retaining walls, bridge abutments, and similar structures
