DESCRIPTION: The J-Drain GRS consists of a impermeable polymeric sheet cuspated under heat and pressure to form a high flow dimpled drainage core. The core is perforated, then bonded to top root resistant filter fabric and bottom protection fabric, specifically designed for Greenroof applications.

The top root resistant filter fabric prevents roots from affecting the efficiency of the drainage/aeration layer and retains soil or other fine particles from being washed away and allows water to pass into the drainage core. The bottom protection fabric safeguards the waterproofing membrane. The core is installed dimple side down to allow water retention. The excess water is collected and conveyed to a proper collection system.
Roll weight is 88 lbs. 7 rolls per pallet (651 lbs, shipping freight class 125).

APPLICATIONS:
  • Under Vegetated Areas
  • Non-Irrigated Roofs
  • Flat Roofs
  • Water Retention
BENEFITS:
  • Polypropylene core
  • Filters fine particles
  • Low cost
  • Easy to install
  • Pre-assembled drain system
  • 100% Post-consumer recycled filter fabric (ECO)
  • Root, mildew & rot resistant
