Ground Gas Protection with Waterproofing Continuity

The Damptec team have recently completed work on a new build property in Barnsley pictured above. The property required waterproofing continuity combined with radon barrier protection.  We carried out this work in accordance with BS 8485:2015 which details the requirements for gas protection and BS8102:2009 for the protection of structures against water from the ground.

We applied a dual waterproofing system incorporating Type A and Type C systems in order to meet the NHBC requirements for a warranty. The team applied Delta Deuxan 2C Water Proofing Solution to waterproof the external face of the walls. We used Koster NB1, a crystallizing cementitious slurry to waterproof the internal surface of the walls. We added Delta geo-drain membrane to protect the Deuxan. Above ground we installed a MemTech PRO R1 radon gas barrier and this will eventually lie beneath the concrete slab. This is a three layer low density polyethylene membrane reinforced with a polypropylene grid. Finally we placed a Delta vented mat beneath the radon barrier in order to provide ventilation beneath the concrete slab.

In line with the requirements of BS 8485:2015 the completed system underwent third party verification and integrity testing. Independent consultants Membrane Testing Solutions provided a certificate of conformance.
