MAPEI Corporation introduced its Below-Grade Waterproofing product line to the North American construction market at the 2016 World of Concrete show. Among the below-grade waterproofing systems introduced at the show were Mapeproof sodium bentonite geotextile waterproofing membranes.
- Mapeproof membranes are constructed using a layer of woven and nonwoven, puncture- and tear-resistant polypropylene fabrics. Encased within these fabrics is high-swelling, self-sealing sodium bentonite.
- Mapeproof 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 other below-grade waterproofing products introduced at the show were Mapethene self-adhering, rubberized-asphalt sheet waterproofing membranes.
- Mapethene 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.
- Mapethene membranes are offered in both high-temperature (Mapethene HT) and low-temperature (Mapethene LT) variants.
Supporting these waterproofing products is a complete line of detailing and accessories, including:
- Mapedrain – A product group that includes seven three-dimensional drainage composites, each engineered for specific site drainage requirements.
- 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.
