Application

Used typically with concrete slab sections greater than 350 mm.

Description

Waterproof membrane composite sheets comprising a robust HPDE backing, a pressure-sensitive adhesive, and a trafficable weather-resistant coating with dual adhesive Preprufe® ZipLap™ for added security. GCP has combined its proven Advanced Bond Technology™ together with more than 20 years of major project experience to produce its highest-performing waterproofing membrane with even more practical and economic benefits.


The membranes develop a continuous adhesive bond to concrete poured against it. This forms micro-compartments to prevent water migration between the structure and the membrane, substantially reducing the risk of leaks.


Suitable substrates:


  • Concrete blinding.
  • Well compacted sand on rolled crushed stone.
  • Rigid insulation.
  • Clay heave boards.
  • Permanent formwork.
  • Removable formwork.
  • 19 mm plywood.
  • Hydroduct drainage sheets.
  • Adjacent sub-structures.


Substrates must be regular and smooth with no gaps or voids greater than 12 mm. They must be sound to eliminate movement during the concrete pour.


System components:

Can be used in conjunction with:


  • Preprufe® Tape: Incorporating Preprufe® coating for continuous concrete adhesion at laps and detail.
  • Bituthene® LM: High performance liquid membrane for detailing terminations at pile caps and pipe penetrations.
  • Adcor® 500S/ 500T: Hydro-expansive waterstop for concrete construction joints.
  • Adcor® 550MI/ 550 T-MI: Hydro-expansive injectable waterstop for added security of concrete construction joints.


Joint laps:

Minimum laps of 75 mm are recommended.
