J-Drain 700 Product Data Sheet


Performs a multi-faceted role by providing protection for waterproofing systems and collecting excess water in plaza decks, split slabs, planters, roof top gardens, and other horizontal surfaces. Planting soil is retained while allowing water to pass into the drainage core . The collected water is then conveyed to a proper collection system.

The core is then bonded to a layer of woven filter fabric. The filter fabric retains soil or sand particles as well as freshly placed concrete or grout, allowing filtered water to pass into the drainage core.
