Application

Manufactured from a blend of high quality virgin polymers Gas Resistant DPC is suitable for use as horizontal or stepped damp-proof courses, including cavity trays, in either solid or cavity walls of brick, stone or concrete. Specifically produced for use on sites contaminated with methane and carbon dioxide this DPC is robust and embossed for improved mortar adhesion.

Description

Manufactured from a blend of high-quality virgin polymers, resulting in a high puncture and tear resistance. This DPC provides excellent protection from methane and carbon dioxide, it is independently certified by the BBA and complies with BS8485:2015+A1:2019. Can be used to form a cavity tray, BS EN 14909 compliant.


Features and benefits:

  • Resistant to water (including water vapour) and radon, methane and carbon dioxide gases passing through the ground floor slab.
  • High mortar bond properties due to its embossing.
  • Complies with NHBC recommendations.
  • UKCA and CE marked in accordance with BS EN 14909:2012.
  • Complies with BS EN 14909:2012 and BS 8485:2015.
