MasterSeal 974, 975, 976: Polypropylene drain board systems

Formerly: Sonoshield DBS 2000, 6200, and 9000

 

How do MasterSeal 974, 975 and 976 drain board systems work?

MasterSeal 974, 975 and 976 constitute 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.

Recommended uses:

MasterSeal 974

  • Retaining walls
  • Tunnel construction
  • Bridge abutments
  • Vertical substrates

MasterSeal 975

  • Foundation walls
  • Plaza decks
  • Planter boxes
  • Lagging walls
  • Below grade with MasterSeal HLM 5000
  • Vertical and horizontal substrates

MasterSeal 976

  • Horizontal substrates
  • Plaza decks
  • Planter boxes
  • Garden roofs and terraces
  • Split-slab construction
  • Parking decks

What are the unique features of MasterSeal 974, 975 and 976?

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

What are benefits of MasterSeal 974, 975 and 976?

MasterSeal 974

  • A cost-effective, high-strength polymeric core and non-woven geotextile filter fabric for vertical installations at shallower depths where moderate compressive strengths and flow capacity are adequate.

MasterSeal 975

  • Offers vertical drain solutions, incorporating a plastic sheet adhered to the back surface of the drain core. This offers a protective layer that prevents die cutting of the waterproofing membrane.

MasterSeal 976

  • 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.
