Cemceil Waterproofing

Cemceil Waterproofing

Liquid-applied waterproofing overlay to protect concrete surfaces.

Cemceil Waterproofing Membrane is a cementitious, fluid-applied waterproofing material designed for use as a liquid-containment or fracture-resistant overlay to protect spalled, cracked, or deteriorated concrete surfaces. Based on a proprietary mixture of a synthetic polymer emulsion, Chemceil incorporates a blend of cementitious and specialty aggregate powders that react to form a tough, flexible, water-tight, and vapor-resistant compound. This water-based membrane is virtually free of volatile organic content (VOC) and qualifies for LEED credits.


  • Forms a monolithic, flexible membrane
  • Tight adhesion
  • Environmentally safe, odorless, VOC compliant
  • Applied to either negative or positive side
  • Can reduce very limited reflective cracking caused by substrate movement
  • Thin section, does not interfere with most building elevations
  • Fluid applied, can easily be applied to irregular shapes (unlike sheet goods)
  • Quick drying (touch dry in 2-4 hours, fully dry in 12 hours)
  • Installed only by professional, factory-trained Dex-O-Tex contractors
