Product Description

Visqueen Ultimate HC BLOK is a highly flexible 0.5mm thick coextruded membrane designed to comply with current guidance on Volatile Organic Compounds (VOCs) vapours and ground gases.

Manufactured using Visqueen’s advanced membrane 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 (vapour phase) such as such as Naphthalene, Benzene, Toluene, Ethyl Benzene and Xylene (BTEX).

The product is available in large roll formats to minimise jointing and quick installation times. The membrane is gold and white, 2.44m x 41m x 0.5mm (100m²), in single wound roll format and packaged in a white outer wrap. The membrane should be installed gold side up.
