Below-Grade Waterproofing Line Bows
Global coatings and waterproofing product manufacturer MAPEI has introduced a below-grade waterproofing product line to the North American construction market.
The line includes Mapeproof sodium bentonite geotextile waterproofing membranes, constructed using a layer of woven and nonwoven, puncture- and tear-resistant polypropylene fabrics, according to the company.
Encased within these fabrics is high-swelling, self-sealing sodium bentonite, the company adds. The membranes are offered in a standard-grade version (Mapeproof HW) and an alternate grade designed specifically for sites where contaminated or salt groundwater is present (Mapeproof SW).
The line also includes Mapethene, described as self-adhering, rubberized-asphalt sheet waterproofing membranes. The membranes are constructed of a 4-mil-thick, impact-resistant, cross-laminated, high-density polyethylene (HPDE) film laminated onto a proprietary 56-mil-thick rubberized-asphalt compound, the company explains. The membranes are offered in both high-temperature (Mapethene HT) and low-temperature (Mapethene LT) variants.
Detailing and accessories complete the line. They include the following:
The company formally introduced the products at the 2016 World of Concrete exhibition, held Feb. 2-5 in Las Vegas.
As the waterproofing products are accepted into the American market, Jason Covington, Business Development Leader and Product Line Manager for the MAPEI Below-Grade Waterproofing category, says the company will gradually introduce additional products and systems.
