Description:

GTD-400 Drainage Composite performs a multi-faceted role by providing protection for waterproofing systems and managing subsurface water around building foundations. Soil backfill is retained while allowing water to pass into the drainage system providing hydrostatic relief.


GTD-400 Drainage Composite consists of an impermeable polystyrene sheet cuspated under heat and pressure to form a high flow dimpled drainage core. The core is then bonded to a layer of non-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.

 

Uses:

GTD-400 Drainage Composite is applied in both above grade and below grade applications. GTD-400 is suitable for new construction and repair. Applications include the following types of waterproofing: horizontal positive side waterproofing (GTS-350); vertical wall positive side waterproofing (GTS-350); and blind side waterproofing (GTS-500). Areas of application include: plaza decks; elevator pits; poured wall foundations; block wall foundations; brick wall foundations; granite/limestone foundations; split slab construction; diaphragm wall (blind side); and green roofs
