What are benefits of MasterSeal 974, 975, 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.
