Protech VOC Flex should be unrolled over the prepared ground or sub-floor which should be swept and free from any sharp protrusions. The A. Proctor Group would advise that Protech VOC Flex is welded to provide protection against VOCs as per CIRIA C716 : 2012 Remediating and mitigating risks from VOC vapours from land affected by contamination. We can advise on site specific jointing techniques where applicable.
In areas where the membrane crosses cavity walls or internal single skin walls, Protech VOC Flex Starter Band should be used in conjunctions with Protech VOC Flex Internal and External preformed corner units. Pipe penetrations should be sealed with Protech VOC Top Hats or Protech GM Flashing Strips. Stanchions and columns should be sealed with Protech Primer and Protech GM Flashing strips.
