Best in class – Quality & Performance

Our products are engineered and manufactured to the highest quality standards (in primarily Germany/Switzerland) and have been successfully used worldwide with zero product failures.

Independently Tested

Our products are independently tested with exceptional results (German Railway, Swedish Vattenfall, Kiwa accredited testing laboratory, SKZ accredited testing laboratory etc)

We’re greener

We’re green building certified (LEED, BREEAM, Nordic Swan Ecolabel) and our carbon neutral production facility is solar-powered and uses recycled rainwater to minimize our impact on the environment.

We lead through innovation

We only do Structural Waterproofing and where others are happy with good enough, we keep innovating to make waterproofing better, more durable, easier to install and more sustainable. In 2019 we were named one of Germanys Top 100 most innovative companies for the third time in four years (*BPA Gmbh).

Certified and accredited

We’re certified by many of the leading international standards including British, German and US/Canada (ICC-ES).

Over 20 years of excellence in waterproofing

We’ve spent the last two decades helping designers, specifiers and contractors select, design and install the optimal waterproofing for their projects.

DUALPROOF® S

Self-healing waterproof liner with Radon and root resistance

  • Superior triple protection waterproofing including active swelling polymers with self-healing capability
  • Resistant to Ground Gases (including Radon) and protects against salt and sulphate attacks
  • Quick and simple installation: Lightweight for easy handling on-site, No need for complicated welding equipment
  • Unaffected by ground settlement
  • May be installed in all weather conditions

PRODUCT DESCRIPTION

As a first line of defense, a great waterproof membrane will stop water coming into contact with your below ground structure. This is important because concrete will invariably crack, be it from settlement, unequal static forces or during curing. Needless to say, water ingress can cause extensive harm to your structure and internal environments and if there are ground gases, they too must be prevented from entering through the sub-structure.

Dualproof® S (Waterproof Membrane) will effectively stop pressurized, aggressive water and radon from penetrating your concrete structure, and is strong enough to withstand root growth and the implications of ground settlement and cracking concrete.

Application – Where to use Dualproof® S

Dualproof® S is for any application where reinforced concrete structures must be protected against groundwater, Radon and contaminated soil. It is highly suitable for external, single layer structural waterproofing of floor slabs and exterior concrete wall surfaces against soil moisture and non-pressurized and pressurized water.

Main areas of application:

  • Structural waterproofing of floor slabs and exterior concrete walls
  • Below ground reinforced concrete structures like foundations and tunnels
  • Pressurized and non-pressurized water
  • Contaminated and/or saline water and where ground gases are present

Technology – How does Dualproof® S work?

Firstly, the tough and flexible exterior PVC-membrane will keep your structure safe from moisture, salts, radon and root penetration. Movement and cracking due to ground settlement will not damage or diminish the performance of the membrane.

Secondly, the super-absorbing and swelling polymers offer water-reactive self-healing, should there be a breach through the PVC.

Thirdly, by forming a permanent bond with the freshly poured concrete, any water is prevented from tracking between the membrane and the concrete thus decreasing the risk of water finding a path through a joint or crack.

Installation – Benefits

  • Fast and easy to install, no need for complicated welding equipment
  • Lightweight and versatile: Easy on-site handling
  • May be installed in all weather conditions
  • For installation instructions, please refer to the Dualproof® product brochure or contact your local Cemproof technical support
