Carlisle Coatings & Waterproofing Miradrain 6000 is a high-strength drainage composite made up of a nonwoven filter fabric that is bonded to the individual dimples of a molded polystyrene core to minimize fabric intrusion into the flow channels caused by backfill pressure. The filter fabric also prevents the passage of soil particles into the core, while allowing water to pass freely. Miradrain6000 is designed for use in high-flow, high-compressive strength, vertical drainage applications where single-sided subsurface drainage is needed. Miradrain 6000 also serves as protection course over Carlisle Coatings & Waterproofing waterproofing membranes.
