Home > Companies > IKO PLC > PermaTEC Hot Melt Monolithic System

PermaTEC Hot Melt Monolithic waterproofing system contains a specially formulated combination of refined bitumen, synthetic rubbers, fillers and other additives which are hot applied in conjunction with carefully selected reinforcement/ detailing fabrics and protection layers to give a waterproofing membrane. The installed PermaTEC system provides a tough, flexible, self-sealing membrane.

The system is suitable for use as the waterproofing layer on most flat roofing systems, when covered by suitable protection or when used in an inverted roof or green roof specification. PermaTEC is also suitable for use as a damp-proof membrane in solid concrete floors or as the waterproofing layer in a typical sandwich membrane used for above or below ground waterproofing in concrete, brick or blockwork structures.

PermaTEC components:

  • PermaTEC ECOWRAP: Hot-applied synthetic modified bitumen. Thickness: 6 mm (2 layer application).
  • PermaTEC Anti-Root: Hot-applied synthetic modified bitumen for Green Roof Applications. Thickness: 6mm (2 layer application).
  • PermaFLASH-D150: Flexible polymer detailing sheet. Thickness: 1.25 mm.
  • PermaFLASH-D500: Flexible polymer detailing sheet. Thickness: 1.25 mm.
  • PermaFLASH-R: Polyester reinforcement membrane.
  • PermaGUARD-F: Polyester based felt protection membrane.
  • PermaGUARD-M: Mineral surfaced felt detail protection layer.
  • PermaGUARD-B: High density polymeric protection board. Thickness: 1.5 mm.

Protection:

All main flat areas of PermaTEC and unexposed upstands must be covered with either PermaGUARD-F bonded as part of the application of the final layer of the hot PermaTEC membrane, or where improved protection is required, PermaGUARD-B bonded as soon as possible after application, in accordance with the specification provided.

After the application of the PermaTEC membrane to both the upstands and horizontal areas, any upstands to be left exposed should be covered with PermaGUARD-M bonded by heat activation of the laid PermaTEC membrane, as solar protection.

Accessories:

IKO PermaTEC approved accessories ensure full compatibility and will be included within the IKO one-point project guarantee.
