Structureseal GPT

  • Sheet

Structureseal GPT is a 1.5mm thick, unique blended polyethylene membrane with a bonded geotextile for pre-applied waterproofing applications, where ground gas or VOC protection is also required. It forms a mechanical bond to the external face of the concrete structure and complies with the latest BS8485, BS8102 and CIRIA C748 codes of practice.


Structureseal GPT can be seam welded to form a monolithic membrane, but the laps can also be sealed using the Gas Seal ancillary tapes.

This product is suitable for use beneath RC concrete structures which extend below ground level including basement structures, or beneath suspended ground floor slabs where required.
