PUDLO GB Self Seal
Application

Can be used as a gas proof or waterproof membrane. Suitable for:

  • All aspects of waterproofing and gas proofing where a Grade 2 or grade 3 environment is required as part of a single or dual system recommended in BS 8102: 2009.
  • Gas proofing or landfill sites.
  • Radon and methane affected areas.
  • Waterproofing foundation, basements and roofs.
  • Podium decks, lift shafts, car parks and subways.

The membrane should be covered with a cementitious screed or similar protective layer as soon as possible after it has been installed – consult manufacturer for details.

Description

An advanced waterproof membrane, manufactured from an aluminium and cross-orientated high-density polyethylene (HDPE) film and a layer of rubber-modified bitumen adhesive.

Features and benefits:

  • Provides high-performance protection from the passage of methane and radon gas.
  • Good overlap integrity due to bitumen-to-bitumen joint.
  • Quick and easy installation; membrane overlaps can be taped.
  • Flexible, and provides good bonding to the substrate.
  • Non-hazardous.
  • Resistant to dilute acids and alkalis.
  • Provides high protection against surface groundwater and soluble salts such as sulphates and chlorides.
  • Can resist up to 6 m head of water when fully supported.
