coreflex dual system plaza deck waterproofing
DESCRIPTION
Various Coreflex applicationsTRANSCRIPT
A Weldable Thermoplastic Membrane…
…with an Active Polymer Core
Coretex – Active Polymer Core
45 mil or 60 mil Thermoplastic Membrane
Thermoplastic Membrane Heat weldable seams Superior chemical resistance High puncture resistance High hydrostatic resistance
Active Polymer Core Layer• Self-sealing layer • Bonds to poured concrete• Cushion/protection layer• Enhances puncture resistance• Minimized lateral flow at concrete
interface
CoreFlex Features
Knitted 5 oz. Polyester
Adhesive flood coating encapsulates fibers
• Inhibits wicking of moisture• Enhances thermoplastic
coating bond to fabric
Exceptional puncture and tensile properties
Base Reinforcing Fabric
Laminated to adhesive coated fabric for superior membrane construction
Encapsulates and bonds to fabric to prevent wicking
Provides durable weldable surfaces
Yellow color of top coat provides visibility and product identification
Produced with DuPont™ Elvaloy KEE to maintain flexibility
Thermoplastic Coatings
DuPont™ Elvaloy KEE
Solid high molecular weight plasticizer• Solid additive - not a liquid plasticizer
Maintains performance longevity
Improves chemical resistance
Enhances welding properties
Prevents age and stress cracking due to loss / migration of plasticizer
Shattered PVC After Loss of Liquid Plasticizer
Thermoplastic Weld
Cortex
KEE Membrane
Film Tear Bond - Membrane ruptures before weld separates
Then the concrete is poured on the membrane
Underslab
The membrane is installed with the BPA Core side up and the Thermoplastic side down with the seams welded.
The concrete is poured
PlazaDeck
The membrane is installed with the BPA Core side down and the thermoplastic side up with the seams welded.
Backfilled WallsA termination bar fastens the membrane to the precast foundation
wall
The membrane is then heat welded below the
termination bar
Lagging / Property Line
Leak Isolation
Leak Isolation – Self Healing• Welded thermoplastic membrane provides a monolithic, hydrostatic ```resistant barrier over the entire surface• If Welded thermoplastic membrane is breached, BPA Core stops leaks from ```migrating to defects in the concrete
