DualProof is a membrane that bonds with fresh concrete. A new generation of modern technology for sealing concrete surfaces below ground level.

Product features:

During the production process, the DualProof TPO/FPO membrane is combined with PP-textile fibers into a homogeneous unit. During concreting, the concrete penetrates the structure of the PP-textile fibers and is physically connected to the membrane over the entire surface. The DualProof PP-textile fiber technology thus eliminates any possibility of water passing between the concrete and the membrane. This means that even with damage to the membrane, water cannot circulate between the membrane and the concrete structure. The TPO/FPO membrane is highly flexible and resistant to cold and reliably bridges cracks in concrete.

Field of application:

DualProof is used for sealing and protecting concrete surfaces in contact with the ground in high-rise buildings, civil engineering in structural systems and tunnels. DualProof also replaces all conventional below-ground sealing materials such as bitumen strips, coatings and sealing membranes made of all types of synthetic materials.

Advantages of DualProof:

Thanks new Thanks to proven production technology, DualProof is a product that provides the user with the following advantages:

• environmentally friendly
• extreme resistance
• resistant to radon gas and protects the structure from pollutants from the soil and salt water,
• simple installation, simple operation,
• high degree of joint strength
• applicable in all weather conditions
• controlled quality (CE mark),
• in accordance with SIA, DIN and BS standards

The double sealing effect of DualProof is manifested in:

• ideal V/C value on concrete edge zones,
• ideal hardening of concrete on the side subsequently loaded with water,
• increasing the proportion of cement in the concrete edge zone and thus low concrete porosity,
• reduces or minimizes surface cracking, keyword “textile reinforcement“,
• reduced and delayed carbonation on the side covered with DualProof,
• In addition to all its positive properties, DualProof acts as a dense, flexible "skin" that, when combined with concrete, forms a whole.

Setting up DualProof

Installing DualProof is simple and effective. The DualProof membrane is laid on a suitable substrate or load-bearing material before concreting, without the need to place a base concrete, which saves time and money. Then the reinforcement and installation of the concrete are carried out. DualProof is then combined with the concrete in a unique physical-mechanical bond and acts as a dense, flexible skin that connects the concrete into a single whole
