Intelligent Waterproofing Solutions

The Firestone RubberGard EPDM membrane offers almost unlimited resistance to hydrostatic pressures.

Firestone has carried out laboratory pressure tests showing that pressure applied to the membrane can reach 35 kg/cm2 (equivalent to a water column of 350 m or 3.4 MPa) without causing damage to the membrane.

Tests carried out according to the EN 1928 standard have shown that, when pressure equivalent to a water column of 40 m (400 KPa) is applied, the RubberGard EPDM membrane and its seams remain waterproof.

Although Firestone recommends a minimum roof pitch allowing adequate run-off, stagnant water will not accelerate the aging of the membrane or the seams.

Broad Range of Chemical Resistance

The Firestone RubberGard EPDM membrane has a relatively wide spectrum of chemical resistance (pH 4 to 10). However, certain products are not compatible with EPDM membranes, such as hydrocarbons, greases, oils etc.

A list of the chemical compounds compatible with the RubberGard EPDM membrane is available on request.

Unlike other waterproofing membranes, the RubberGard EPDM membrane does not have incompatibility problems with polystyrene, old asphalts, PVC membranes etc. It is compatible with almost all waterproofing substrates.

As a result of the large membrane sizes, good mechanical properties and easy assembly process, RubberGard EPDM roofing systems are quick and easy to install.

In an occupation that is heavily weather dependent, the installation speed of the RubberGard EPDM membrane is a major advantage.
