Sikaplan®-976

(formerly MSeal 976)

POLYPROPYLENE DRAIN BOARD SYSTEM

Sikaplan®-976 is part of a series of polypropylene drain board systems that significantly reduce the amount of water coming into contact with the waterproofing membranes, relieve hydrostatic pressure, and extend the life of the waterproofing system.

Sikaplan®-976 is a high-strength drain board ideally suited for horizontal applications. It utilizes a high-strength woven monofilament filter fabric that offers ideal drainage and support under concrete, soil and beddings.

  • High-impact polypropylene core provides the toughest drain system available
  • Dimpled core construction helps produce high water-flow rates
  • Water-flow control relieves hydrostatic pressure on buildings and extends the life of waterproofing systems

SUBSTRATE PREPARATION

Surfaces to receive drain board should be relatively smooth and free of sharp or protruding objects.

APPLICATION

Installation on Horizontal Surfaces

  1. The substrate below the Sikaplan®-976 panels should have a minimum 2% slope.
  2. Install drain panel with the filter fabric side up.
  3. Adhere the drain panel at 10 ft (3.3 m) centers using two-sided mastic tape when necessary.
  4. Overlap the sheets using the flat tab sections of each. Overlap the fabric onto the preceding panel and adhere the overlapped fabric with adhesive tape if necessary to prevent soil, sand, and concrete from entering the panel during construction.
  5. Start the installation at the lowest point to ensure sound drainage and to create a shingling effect in the installation.
  6. Overlapping of Sikaplan®-976 panels in horizontal installations must take slope and water flow into account. Drain panels must be shingled in the direction of the water flow using sound waterproofing practices.
  7. Ensure that fabric covers all exposed core edges.
  8. Place backfill as soon as possible after installation. Take care not to damage the drain panels during backfilling.
