Type N Sitesealer

Application

For use on oversite concrete blinding, to seal against rising gas and as a general damp-proof membrane and tanking.

Description

An extremely low gas permeability damp proofing membrane with methane and radon resistant qualities.


Features and Benefits:

  • High resistance to water pressure, water vapour transmission and gas transmission.
  • Cross-ply orientated construction.
  • Self-seal bonding, eliminates joint heating and drying.
  • Combined water and gas protection.
  • Incorporates a lap-link edge for jointing.
  • Integrates with cavity barrier.
  • Integral self-adhesive edge.
  • Reinforced.
  • Radon and methane gas resistant.
