Carlisle Miradrain Gr9400 4'X 50' Drainage Composite Roll

4" x 50' x 1", Black/Blue, High Impact Polypropylene Core, Solid, High Capacity, Drainage Composite Roll

CCW MiraDRAIN GR9400 is a high capacity retention/drainage composite consisting of a three-dimensional, high impact polypropylene core with holes allowing water retention and drainage. A moisture retention mat fabric is bonded to the retention side of the molded core. The moisture retention mat fabric also serves as afilter medium to prevent the passage of particles into the water reservoirs while allowing excess water to pass freely into the drainage system.
