Building Regulations require proper precautions be taken to prevent danger to health and safety when building on contaminated land. Visqueen Gas Barrieroffers a safe solution for the protection of buildings against Methane, Radon, Stythe (a gas commonly found from disused mines, also known as blackdamp) and Carbon Dioxide; when installed in accordance with the relevant codes of practice such as BRE, CIRIA and the Chartered Institute of Environmental Health Ground Gas Handbook.
For ease of identification on site, Visqueen Gas Barrier is coloured blue on one side and silver on the other.
The barrier combines strength and performance with flexibility and easy installation. Visqueen Gas Barrier also acts as a damp proof membrane.
In this video, we demonstrate how to create a joint using Visqueen Gas Barrier and a pre-formed 90 degree corner unit.
The tools required for this are, a roller with a neoprene wheel and a sharp knife or pair of scissors. To complete the job you will need Visqueen Gas Barrier, Visqueen double sided jointing tape, Visqueen Gas Barrier foil jointing tape (which is single sided) and the pre-formed 90 degree corner unit, which is reversible.
To ensure that you create the best seal, we recommend that the double sided tape is applied to the corner unit before you start the installation process. This should be done in a clean and dust free environment.
Apply the tape to the edge of the corner unit and use the roller to apply pressure across the tape to ensure that it is fully bonded to the corner unit.
Repeat the process for the other side of the corner unit. Here is an example of the completed corner unit;
Position the unit in the corner of the blockwork ensuring a snug fit. Next, peel off the release film on the tape and position the gas barrier on the exposed tape ensuring that the membrane covers the whole width of the tape.
Ensure a gas-tight seal is created by applying pressure to the newly formed joint, using the roller;
Now use the gas barrier, foil jointing tape and position it at halfway over the lap joint;
Finally, apply pressure to the joint, using the roller;
The installation is now complete.
For ease of identification on site, Visqueen Gas Barrier is coloured blue on one side and silver on the other. The barrier combines strength and performance with flexibility and easy installation.
