Product Description

Visqueen Ultimate VOC BLOK is a flexible membrane designed to comply with current guidance on Volatile Organic Compounds (VOCs) and ground gases.

Manufactured using Visqueen’s advanced barrier technology and drawing on our extensive knowledge and expertise in gas protection, Visqueen has developed a new flexible barrier membrane suitable in brownfield applications that are affected by aggressive chemicals such as Benzene, Toluene, Ethyl Benzene and Xylene (BTEX). In accordance with BS8485-2015 and C748, VOC BLOK is the only membrane that does not require a protective layer.

The product is available in large roll formats to minimise jointing and quick installation times. The membrane is grey and black and 2.44m x 41m x 1mm (100m²), in single wound roll format and packaged in a blue outer wrap. The membrane should be installed grey side up.
