SOLCO GROUND GAS PROTECTION, VOC & HYDROCARBON BARRIERS

As demand for housing continues to increase, so does the pressure to develop on brownfi eld and other
potentially dangerous land. Any buildings constructed on or near gas contaminated land face a genuine risk
of hazardous gases penetrating up through the fl oor. If not allowed to escape, these gases can build-up and
concentrate to either asphyxiating or even explosive levels, causing a signifi cant health and safety risk. The
1991 Building Regulation C2 requires that the occupants of buildings should be protected from the effects of
gaseous contamination in the ground. Importantly, the choice of membrane should not only be down to its gas
permeability, it should also be selected according to its ability to withstand the construction process.
Solco’s Gas Protection membranes comply with all the latest guidance on the use of gas resistant membranes.
They are BBA Certifi ed for use in a range of situations and provide outstanding protection against hydrocarbon
and VOC vapours, as well as common ground gases such as carbon dioxide, methane and radon. These
membranes also offer exceptional robustness and long-term reliability.
Solco’s Hydrocarbon Barrier offers a safe solution for the protection of buildings and occupiers against all levels
of hydrocarbons, methane, carbon dioxide and radon ingress. Typically, these are sites previously used as petrol
stations, coalfi elds landfi ll sites, contaminated industrial sites, Fracking sites, and heavily contaminated sites.
The membrane also acts as a damp-proof membrane. Due to the fl exible nature of our hydrocarbon Barrier’s
they also provide a fl exible membrane suitable for various applications unlike rigid HDPE rich membranes.
Solco membranes are designed to withstand the most aggressive environments. Testing has been completed in
accordance with BS8485:2015 and C748 to determine the permeation rates for Methane, Carbon Dioxide, and
a range of VOC’s. Immersion testing has also been completed to for Chemical Resistance to EN 14414 and
EN 14415. The level of testing is to prove the suitability for these
challenging environments.
Solco can also supply a Liquid Gas Barrier which can be used
to protect most building surfaces form the effect of liquid and
water vapour, carbonation and to act as a gas barrier to prevent
the ingress of Methane, Carbon Dioxide, Radon and VOC’s. As
the product is a barrier to moisture it can be used as a DPM on
fl oors and walls. Solco’s Liquid Gas Barrier is tested to meet the
requirements of BS8485:2015.
Solco’s Gas Protection System(s) also includes a range of
accessory products to the Barrier System including, Geotextiles
for protection of the Gas Barrier, Void Ventilation Geocomposites,
DPC’s and self-adhesive products for complex installations.
