Wabo® Crete Membrane

Membrane sealing expansion joint system

The industry’s original elastomeric concrete system, Wabo®Crete Membrane is a high performance joint sealingsystem specifically designed to meet the unique demands of parking structures. The Wabo®Crete Membrane systemcombines a choice of versatile elastomeric glands with hole patterns in the flange areas providing secure mechanical attachment between the concrete substrate and

• Sealing expansion joint openings on parking decks.

• New construction or repair and maintenance of existing expansion joints.

• High impact and repetitive loading conditions

Wabo®Crete II elastomeric header. The tough and durableheader flexes with deck loads and seals out moisture. Installed by certified applicators, the Wabo Crete® Membrane systems are available with the strongest warranties in the industry.

• Rubber seals are cut to length and shipped onpallets per limitations of shipping methods:

ELASTROMERIC CONCRETE (WABO®CRETE II)

TYPICAL PROPERTIES*

Wabo® Crete Membrane

• Concrete substrates must be abrasive blasted to remove alllatencies and contaminants which may causebonding problems.

• Apply Wabo®Bonding Agent (primer) to surface of theproperly prepared concrete prior to installation of Wabo®Crete

II. Do NOT apply Wabo®Bonding Agent to steel substrates. There must be no visible moisture prior to theapplication of the primer. Primer can be brush applied. Do NOT allow primer to dry prior to placement of Wabo®Crete II.

• Thoroughly pre-mix (approximately 20 seconds) Part Bseparately before pouring entire contents of Part B into clean20 litre container. Add Part A and mix both componentsfor approximately 30 seconds, or until well blended.

• Slowly add the aggregate component to the mixed liquids andmix until all aggregate is coated (approximately 1 minute). Thismix can be poured into the properly prepared blockout,in which the primer is still wet. The material will flow and self-level. Use a margin trowel to work material and finish surface.

• For sloped conditions, add Wabo®Non Flow Additive to theliquid-aggregate mixture.

• The elastomeric gland shall be field installed in longest possiblecontinuous lengths. Install the expansion control systemin accordance with manufacturer’s typical details andinstallation procedures.

• Install when concrete substrate is clean,sound, dry, and cured (14 day minimum).

• Do not install if the joint’s anticipatedmovement will exceed the system’smovement range.

• Protect the work area with appropriate plasticsheeting.

• Minimize splice points by installing sealsin longest possible continuous lengths.

• Do not allow any of the components tofreeze prior to installation. Store allcomponents out of direct sunlight in a clean,dry location between 50˚F(10˚C) and 90˚F(32˚C).

• Shelf life of chemical componentsis 12 months from date of manufacture whenstored in undamaged, unopened packaging.

• Periodically inspect the applied material andrepair localized areas as needed. Consult aBASF representative for additionalinformation.

• Make certain the most current version of theproduct data sheet is being used.

• Proper application is the responsibility of theuser. Field visits by BASF personnel are forthe purpose of making technicalrecommendations only and not for supervisingor providing quality control on the jobsite.
