+44 (0)1403 799600 www.cordek.com
Application

Used within foundation construction, predominantly to prevent the transmission of ground gases in both horizontal and vertical applications. Can be installed in both vertical and horizontal applications, above and below ground.

Description

Self-adhesive membrane which is manufactured using an aluminium/ polythene laminate coated on one surface, with an additional layer of self-adhesive polymer modified bitumen.

Features and benefits:

  • Incorporates an aluminium foil core to provide resistance to the passage of methane, carbon dioxide and radon gases.
  • Provides additional waterproofing protection to the structure as part of an overall waterproofing system.
  • Adhesion properties to primed surfaces.
