Mel-Drain DB




NO. 719-PD



SEALTIGHT MEL-DRAIN DB is a dimple raised, molded polystyrene sheet bonded to high strength polypropylene fabric. This geocomposite allows the passage of moisture through the fabric while preventing fine soils from entering the drainage channel. Various drain designs are available, depending on soil pressure and flow specifications. (An optional polyester backing film is recommended when used in conjunction with flexible waterproofing material.) The family of MEL-DRAIN DB products provides excellent protection in vertical, horizontal, and site applications.

SEALTIGHT MEL-DRAIN DB is the perfect compliment to the MEADOWS family of moisture protection solutions. Used in conjunction with a total MEADOWS system, MEL-DRAIN DB is the ideal choice for enhanced waterproofing protection of basement walls, plaza decks, earth sheltered homes, commercial buildings, retaining walls, underground parking, site drainage, etc.

For vertical, below grade applications, unroll MEL-DRAIN DB with flat, film side against the wall or waterproofing material. MEADOWS Pointing Mastic is an excellent adhesive, compatible with this installation. The flat side core material is overlapped to provide a continuous drainage layer. Extra filter fabric is provided at the edges for overlapping with the next sheet. MEL-DRAIN DB is easily cut with construction knives or scissors.

For horizontal applications, unroll and overlap so that water runs with overlap. Add appropriate ballast as needed to hold down drainage board.
