Thermoplastic waterproofing membrane with active polymer core (APC): Setting the standard for waterproofing membrane strength, durability and performance for more then 50 years, COREFLEX consists of a thermoplastic membrane integrally bonded to a proprietary Active Polymer Core (APC) layer. Combined with fully welded seams, this provides the ultimate waterproofing protection. Whether your project requires foundation waterproofing, plaza deck restoration, or green roof construction, COREFLEX provides superior waterproofing performance.
The COREFLEX reinforced thermoplastic membrane is engineered to resist high hydrostatic pressure and groundwater contaminants typical of foundation conditions. In addition to waterproofing performance, the membrane has an extremely low water vapor transmission that qualifies it as a Class “A” Vapor Retarder per ASTM E1745.
Dual membrane protection: If COREFLEX’s thermoplastic membrane component is ever punctured or damaged, the superior water barrier performance continues with an APC technology layer that is engineered to actively control water ingress by swelling to produce a reliable seal at the breach. To maximize the performance of the APC Technology, the layer is installed in direct contact with the concrete to be waterproofed, thus preventing water ingress into the structure. With COREFLEX, each membrane overlap seam utilizes both a conventional weld and an overlap assembly of the APC Technology to assure water-tightness. This combination of passive and active barrier technologies provides enhanced seam performance and eliminates the reliance of seam integrity strictly on installation labor.

COREFLEX 60: A dual component waterproofing membrane system that combines a modified PVC reinforced thermoplastic membrane with an Active Polymer Core (APC) layer into one high performance, easy to use product. This composite membrane provides both a fully welded thermoplastic membrane with an integrally bonded self-sealing active waterproofing layer to assure optimal performance. No other product fits the range of installation conditions that COREFLEX does; including underslab, property line walls, backfilled foundation walls, tunnels, earth covered structures, new and restoration plaza decks, split-slab construction and greenroofs.
COREFLEX XP: A dual-component waterproofing membrane system that combines a modified PVC reinforced thermoplastic membrane with an XP technology core layer in to one high performance, easy to use product. COREFLEX XP offers the same installation and performance benefits as COREFLEX 60, but features XP technology, the latest innovation in active waterproofing. This advanced polymer technology provides exceptional performance in a wide range of ground contaminates, including high-salinity conditions. COREFLEX XP should be used with other XP detailing products: CORETEX XP, SEAL-X XP, and WATERSTOP XP.
Due to the location of the building in the Wynyard Quarter there is a high concentration of contaminants, high water table and saline. A waterproofing membrane was required not only to handle hydrostatic pressure but also to act as a vapour barrier protecting indoor air from potential ingress of hydrocarbon vapours.READ MORE
