WaboCrete® Membrane Gen II

Parking Garage Expansion Joint - Watertight and Seismic Movement Capable Membrane/Nosing System for concrete parking garages, decks, and car parks including exposed top decks, stadiums, etc.

Sika Emseal now supports and sells all Wabo^© Commercial products.

A seismic concrete expansion joint for parking garages and carparks, WaboCrete® Membrane Generation II is a durable thermoplastic-rubber sealing system with high-strength elastomeric concrete nosing material.

The preformed, heat-weldable thermoplastic rubber sealing gland can accommodate unforeseen outward structural movements (ie: seismic, shrinkage, creep or other unknown movements) beyond its relaxed width without sacrificing performance and watertightness.

The thermoplastic rubber is heat-weldable, allowing for complex transitions to be factory-welded and watertight.

Provided with the option of WaboCrete® Parking Series Elastomeric Header in black or Emcrete II, this self-levelling, two-component polyurethane nosing flows through the side flanges of the rubber sealing gland into the blockout encapsulating the flanges and locking the system in-place and bonding to the concrete substrate.

Sizes

Models are available for mean-temperature joint sizes from 1-inche (25mm) up to 6-inches (150mm). See sizing chart on Product Data Sheet.

Movement

Movement as a percentage of nominal joint size varies by model. Up to or in excess of 100% of nominal joint size movement capability is typical in most applications. See Movement Table in Product Data Sheet.

Color

Black color for sealing gland.
Black color for nosing.

Uses

Parking decks/car parks
Stadiums
Decks
Mall bridge connectors
Roadways
For cast-in-place, precast and post-tensioned concrete substrates

Composition

Evolved from the largely obsolete “compression seal“, WaboCrete®Membrane GenII belongs to a product type sometimes referred to as a “winged compression seal.” Innovation to improve movement capability while overcoming compression set and adhesion in tension in extruded seals, led eventually to Emseal’s high-movement, low-strain Gen II series for joints up to 6-inches (150mm).

Built in nosing stop that facilitates efficient installation of the nosing material at a height above the main seal that provides resistance to damage during snow plowing.

Design Considerations

System will not perform where there is unsound substrate or improper blockout preparation. The joint-gap and the blockout area must be perfectly clean and dry.
Minimum substrate temperature at time of installation and for 4-hours following installation is 45°F (7°C).

Transitions & Terminations

Anyone can make an expansion joint watertight in cross-section. It is at changes in direction and plane, and between different technologies that joints leaks. Sika Emseal has addressed this problem with custom-quick, factory-made transitions and terminations to fit field measurements. Factory-fabricated assemblies reduce in-field labor time and ensure that continuity of seal is preserved. And, each weld is strengthened with a reinforcing band of welded thermoplastic-rubber sheet and water-tested before it leaves the plant.

Where joint movement is perpindicular to the run of the joint, this will induce shear movement in the seal. Most extrusion can handle only minimal amount of ‘racking’ or shear movement. Emseal’s unique shear pocket technology provides a means to handle large shear movement

Maintenance

As with any construction product, the useful life of the material can be maximized with routine inspection and repair if required.
Clearing of surface debris and inspection will reveal any damage to the product or adjacent substrates that might affect building performance.
In the event of damage to the nosing, the damaged section can be removed, the area primed, and replaced with freshly mixed material. Since the product develops good adhesion to itself, the newly applied section becomes an integral part of the nosing section. The contact surface of the cutout must be free of loose debris, dust, dirt, moisture, and other contaminants. Should the sealing gland be damaged replacement sections or patches can, in many cases, be field welded into position.
The durability of expansion joint systems, is significantly affected by maintenance and snow removal practices. This article provides guidance on appropriate snow removal practice.
