Visqueen Ultimate GeoSeal is a pre-applied membrane designed to comply with current guidance on waterproofing, 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 barrier membrane suitable in applications that are affected by aggressive chemicals such as Benzene, Toluene, Ethyl Benzene and Xylene (BTEX).
The product is textured on one side to aid adhesion to concrete and available in a large roll format 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 clear outer wrap.
The membrane should be installed grey and textured side up.
Visqueen Ultimate GeoSeal is suitable for the following applications:
■ Waterproofing applications to BS8102:2009 type A
■ Slab edges and permanent shutter work
■ Tanking below ground structure e.g. lift pits
■ VOC/Hydrocarbon contaminated sites in accordance with CIRIA C748
■ Carbon dioxide and methane sites in accordance with BS8485:2015 The membrane can withstand normal on-site foot traffic and the activities associated with the laying of a reinforced concrete slab without the need for additional membrane protection. In addition, when applied with welded joints the membrane can provide protection against hydrostatic water pressure.
