Masterseal 975 & 976
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. 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.
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
