SELF-ADHESIVE BITUMINOUS MEMBRANE
GROUND BAND
GROUND BAND is the self-adhesive and self-sealing bituminous membrane tested for protection against radon gas and methane gas, which are harmful to health in case of high concentration in indoor environments.
Practical and fast installation, no flames are required, minimising risks for the wood.
GROUND BAND, THE BITUMINOUS MEMBRANE FOR WATERPROOFING AND RADON PROTECTION OF FOUNDATIONS
The self-adhesive bituminous GROUND BAND membrane installation is effective from +5 °C to +30 °C, thanks to the special elastoplastomeric bituminous compound; the sheath remains flexible down to -30 °C.
All versions are supplied with the liner pre-cut to facilitate installation in corners or complex locations, but also over large areas to avoid excessive misalignment of the layers.
The special elastoplastomeric bituminous compound and the cross-laminated high-density polyethylene backing film make the membrane completely waterproof and resistant to punching shear.

It can be applied on various smooth building substrates such as timber, OSB boards without additional surface treatment. The surfaces must be dry, free of dust and solvents such as grease or oil. We recommend the use of PRIMER for rough surfaces such as rough OSB boards. Once the tape has been applied, it is recommended to use the special roller RLL45 to obtain a perfect application.
