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 company said it formally introduced the product line during the 2016 World of Concrete, held Feb. 2-5 in Las Vegas.

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:

  • Mapedrain: A product group that includes seven three-dimensional drainage composites, each engineered for specific site drainage requirements; and
  • Mapebond: A product group that includes four contact adhesives, which meet the varied site conditions and the various VOC regulations in place at different locations. 

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.
