DualProof T

DualProof T Membrane is a pre-applied, composite waterproofing membrane which forms a permanent mechanical bond with the fresh concrete preventing the tracking of water between the waterproofing membrane and the concrete.

DualProof T Membrane consists of a special non-woven PP-Fleece, which is co-extruded with a flexible transparent PVC Membrane. The fresh concrete forms a mechanical bond with the PP-Fleece.  The system is specifically designed for the waterproofing and protection of below ground reinforced concrete structures.

DualProof T Membrane is designed to perform for the lifetime of the structure provided it is not damaged by subsequent building operations.

Key Features & Benefits

  • DualProof T Membrane forms a permanent mechanical bond with the fresh concrete and prevents tracking of water between the membrane and the concrete.
  • When used in double-sided formwork, the cured concrete will be visible through the installed membrane, this allows remedial works of the concrete be undertaken prior to backfilling if required.
  • Provides all Grades of Protection according to BS 8102:2009
  • DualProof T Membrane is pre-applied
  • May be installed in all weather conditions
  • Fast and easy to install
  • No requirements for complicated welding equipment
  • Lightweight and versatile-Easy on-site handling
  • Protects concrete against salt and sulphate attack
  • Unaffected by ground settlement.
  • May be used in salt-water conditions
  • Offers protection against Radon in accordance with BS 8485:2015
  • Several independent test-reports
  • Designed and manufactured in Germany

Specification Tip for Design Professionals:

DualProof T Membrane may be specified by name or by using the following description: a propriety 1.7mm PVC composite waterproofing membrane, consisting of a special non-woven PP-Fleece, which is co-extruded with a flexible transparent PVC Sheet. The fresh concrete forms a mechanical bond with the PP-Fleece and prevents water from tracking between the membrane and the concrete. The system is especially designed for the waterproofing and the protection of below ground reinforced concrete structures.

Test Results:

  • CE Marking DIN EN 13967
  • German DIN 18195 Standard
  • German DIN V 20000-202 approved
  • DIN V 20000-202 approved
  • General German Test Report PG-ÜBB / abP
  • CPR Certificate (the Construction Products Regulation) – EN 13967:2004 + A1:2006

*The membrane is independently tested and approved for use as a barrier against Radon Gas. In applications where methane or CO2 resistance is required DualProof T Membrane will act as barrier against these ground gases, when installed in accordance with BRE Report 414 the membrane will be compliant with the recommendations made in CIRIA C665:2007 Assessing risks posed by hazardous ground gases to building, BS 8485:2015, BRE Reports211 & 212 and NHBC Standards. Guidance is given in the Ground Gas Handbook, 2009 and the manufacturer’s technical literature.
