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.
Description
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.

Description
The application surface must be dry, free of dust and grease, and not be anti-adhesive. Surface elements must be removed so that the membrane is not damaged during application.
Recommended use
Suitable for application on various smooth building substrates, such as timber or OSB panels, without the need for additional surface treatment. If the tape is applied to brick or concrete surfaces, the use of a primer such as BYTUM PRIMER is recommended.
The complete list of approved application surfaces can be found in the specific instructions provided by the manufacturer. The product is tested for protection against radon and methane gas.
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 does not require the use of flame, minimising risks to timber.
Installation
Unroll the membrane and partly remove the protective release film from the adhesive side to facilitate installation on both sharp-edged and flat surfaces. Continue by fastening each layer to the substrate with a mechanical fastening device to ensure installation stability. The sealing is completed by removing the remaining liner and adhering the tape to the support.
Once tape installation is complete, a pressure roller or a hot air gun such as the HOT GUN must be used to ensure perfect adhesion.
Further details regarding installation can be found in the specific instructions provided by the supplier.
