Wabo Crete Membrane - wbacorp.com

1 wabo Crete Membrane Membrane sealing expansion joint system Features Benefits The Membrane seals combined with WaboCrete II elastomeric Watertight concrete provides a monolithic applications sealing system preventing water from leaking through the expansion joint opening. WaboCrete II has been Energy developed to adsorb the impact adsorbing loads associated with typical parking deck applications. Heat Provides a continuous, weldable watertight seal at transitions seals and intersections. Proven Over 20 years of successful RECOMMENDED FOR: performance installations. Sealing expansion joint openings on parking decks. DESCRIPTION: The industry's original elastomeric concrete New construction or repair and maintenance system, wabo Crete Membrane is a high of existing expansion joints.

2 Performance joint sealing system specifically High impact and repetitive loading conditions designed to meet the unique demands of parking structures. The wabo Crete Membrane system combines a choice of versatile elastomeric glands PACKAGING/COVERAGE: with hole patterns in the flange areas providing secure mechanical attachment between the Rubber seals are cut to length and shipped on concrete substrate and wabo Crete II elastomeric pallets per limitations of shipping methods header. The tough and durable header flexes with wabo Crete II. deck loads and seals out moisture. Installed by o PTA gal container certified applicators, the wabo Crete Membrane o PTB 1 gal container systems are available with the strongest warranties o PTC 60 lbs aggregate in the industry.
