Coreflex

Performance

Applications

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.

Limitations 

• COREFLEX is designed for waterproofing applications where the product is properly covered and confined.
• COREFLEX should only be installed after substrate preparation has been properly completed and is suitable to receive the waterproofing system.
• COREFLEX should be used with structural grade reinforced cast-in-place concrete with conventional forms that produce a smooth surface.
• For Shotcrete applications using COREFLEX, reinforced shotcrete walls must be a minimum of 200 mm thick, applied from the bottom up in their full wall structural design thickness in a single application per shotcrete lift.
• COREFLEX should not be installed in standing water or over ice.
• Site groundwater samples should be submitted to Allco for compatibility testing.
• COREFLEX is designed for use under reinforced concrete slabs 150 mm thick or greater with a mud slab substrate.
• COREFLEX is capable of bridging typical shrinkage cracks in concrete up to 1.5 mm.
• COREFLEX membranes are not designed to waterproof expansion joints. Consult with Allco regarding all expansion joint applications and limitations
