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
