Viking CIAP-4TA

Product Description

CIAP-4TA is a torch applied modified bitumen waterproofing membrane composed of carefully selected asphalts (bitumen) having superior modifying characteristics, blended with high quality polypropylene resins. CIAP-4TA is reinforced with spunbond polyester fabric. CIAP-4TA waterproofing membrane yields the following performance characteristics:

  • Impermeable to water
  • Excellent adhesion
  • Puncture resistant
  • Longevity
  • UV Resistance
  • Resistant to acids and most bases
  • Excellent workability

Spunbond polyester fabric, used as a reinforcement in CIAP-4TA has isotropic mechanical properties giving the composite membrane similar mechanical characteristics in all angular directions in relation to the membrane surface. Spunbond polyester fabric imparts the following properties to the composite membrane:

  • Flexibility
  • Elasticity
  • Fatigue resistance
  • Deterioration resistance
  • Puncture resistance
  • Mechanical strength
  • Tear strength
  • Dimensional stability

CIAP-4TA incorporates a patented wet talc slurry application to prevent blocking of rolls and to provide a smooth, even torching surface. Polyethylene burnoff film is contained on the torchable face of the roll. This film and embossed pattern act as a “sight indicator” for the applicator in determining the proper flow needed to insure adequate bonding of plies and seams.

After installation of the roofing membrane is complete, the surface may be coated with a CI APPROVED ROOF COATING to increase the overall reflectivity of the system and/or fire rating. CI recommends that a period of at least 45 days elapse before roof coatings are applied. This will effectively allow the membrane to “cure” and accept the roof coating.

CIAP-4TA, in addition to being an excellent waterproofing membrane for use in roofing applications, may also be used in the waterproofing of:

  • Road structures and bridges
  • Water reservoirs and artificial canals
  • Foundations
  • Basements
  • Verandas and galleries
  • Multi-story car parking and garages
  • Roof gardens
