Trocal PVC Membranes

The PVC waterproofing membrane is one of the best high polymer membranes in the waterproofing market.

PVC is applied by a process of heat welding seam technology, which allows for one single piece of PVC roofing to cover an entire roof's surface and eliminate seams and joints providing excellent flexibility. 

This makes PVC roofing applicable to practically any shaped surface PVC waterproofing membrane has excellent UV-resistance property with its lifetime over 20 years.

PVC roofs are installed in three different ways:

  • Mechanically Attached - the PVC roof is held in place by being attached to the substrate/deck using screws or other types of fasteners, depending on the deck type.
  • Fully Adhered - the PVC roof is attached to the substrate using special adhesive (glue). There are different adhesive options but that's not something most readers will care about.
  • Ballasted - the PVC roof is laid across the roof loosely, secured only at the roof perimeter and around roof penetrations such as pipes, air conditioning units, etc., and held in place with ballast which usually consists of smooth river rock although other options are available.
