ENVIROSHEET Waterproofing Membrane

Always Reliable. Always Uniform.

ENVIROSHEET is a self-adhering sheet membrane for high strength, chemical resistance, and superior adhesion.


It's for long term performance.


Tough, reliable, and easy to put in place

For structural concrete, masonry, and wood surfaces, ENVIROSHEET is the reliable waterproofing solution for:

Exterior Use

  • Foundation walls
  • Tunnels
  • Earth-sheltered structures
  • Above- and below-grade split-slab construction, including balconies and parking decks

Interior Use

  • Mechanical rooms
  • Kitchens
  • Bathrooms
  • Laboratories


For high hydrostatic resistance, ENVIROSHEET’s two-component membrane combines the high strength and chemical resistance of high-density polyethylene film (HDPE) with the superior adhesion and self-sealing ability of modified asphalt, blocking water from the surface of a structure for the long term with uniform and consistent protection.


Easy to position

ENVIROSHEET installs simply over a properly prepared and primed substrate. Cold applied—eliminating the need for heating equipment and danger from hot materials—simply cut ENVIROSHEET on site and position in overlapping sheets, letting it contour to substrate transitions and form around penetrations.

The result is always a reliable, uniform waterproofing system.


ENVIROSHEET LT for low temperature installations

For low-temperature installations (when temperatures are between 60°F and 25°F (16°C to -4°C)), use specially-formulated ENVIROSHEET LT to protect the selected surface with all the same strength, reliability, and waterproofing capabilities of ENVIROSHEET.


How it does it

ENVIROSHEET features 1.4 mm (56 mil) of rubberized asphalt integrally bonded to a 0.1 mm (4 mil) cross-laminated, high-density polyethylene film (HDPE) to create a waterproofing barrier. Self-adhering, ENVIROSHEET is designed to be cold-applied, requiring no special equipment or adhesives to install it to a prepared surface.
