MasterSeal 974, 975, 976
Polypropylene drain board systems
Formerly: Sonoshield DBS 2000, 6200, and 9000
How do MasterSeal 974, 975, 976 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.
Below grade with MasterSeal HLM 5000
Vertical and horizontal substrates
Garden roofs and terraces
What are the unique features of MasterSeal 974, 975, 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, 976?
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.
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.
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.
