Application

- Damp-proofing against:

  • Rising humidity caused by capillary action.
  • Standing water, for slab-on-ground foundations, column footings, strip foundations and walls.
  • Diffusion, effusion, absorption.

Description

DualProof is a fully and permanently bonded, self-adhesive, composite sheet which does not only waterproof but protects against gas and chemicals. It consists of a sealed two layer highly flexible PVC membrane laminated with a non-woven polypropylene fleece. DualProof is cold/ pre-applied, and is installed without heat or open-flame. It is applied before the steel reinforcement is fixed and the concrete poured.

Advantages:

  • Waterproof, gas proof and gives concrete protection against chemicals such as sulfate, chloride, carbonate, hydrogen carbonate etc.
  • Tough and resistant, quick and easy to install, high compound shear strength.
  • Can be installed in every season regardless of temperature and weather condition.
  • No need for complicated welding equipment or specially trained staff, overlapping can be easily secured with CEM 805 adhesive.
  • Self-adhesive bonding properties on contact with poured concrete.
  • Seals small cracks in the concrete.
  • Can be used in saltwater conditions.
  • CE marked and DIN certified.

Applications:

- Damp-proofing against:

  • Rising humidity caused by capillary action.
  • Standing water, for slab-on-ground foundations, column footings, strip foundations and walls.
  • Diffusion, effusion, absorption.

- Concrete protection against:

  • Various ground gases.
  • Chemicals such as (sulfate, chloride, carbonate, hydrogen carbonate etc).
  • Contaminated ground water.

- Waterproofing resistance:

  • Water under hydrostatic pressure.
  • Lateral water migration for deep, one or multilevel below grade structures.
  • Approved to German standard DIN 18195 ‘pressurized water situations’.
  • An additional sealing membrane for all watertight concrete structures.
