SWEPCO Heavy Duty PolyForm

A tough reinforcing fabric especially designed for renewal of gravel roofs. When this remarkably strong 100% polyester fabric is embedded between two coats of Heavy Duty or Flex•Shield® Roof Coating, an economical new waterproofing membrane with outstanding performance characteristics is the result. Superior strength, stretchability and durability produce a roof which will outlast conventional approaches. It “conforms” to rough gravel surfaces, helping to eliminate future blistering problems and also reducing the likelihood of punctures.
  • Especially designed reinforcing fabric for liquid applied coating applications on gravel roofs
  • 100% polyester reinforcement provides exceptional strength
  • Special weave allows it to conform readily to rough surfaces
