Wabo® Watson Bowman Acme

The latest in expansion joint technology for parking structures will be exhibited from Wabo® by Watson Bowman Acme. Wabo systems provide high quality, high performance solutions which also address requirements for sustainability, aesthetics, water tightness and fire protection. RAB Associates (UK) Ltd., the UK distributor for WBA will be on hand to demonstrate and discuss the innovative systems.

RAB Associates are very proud to be the UK distributor for the Wabo® range of products by Watson Bowman Acme. This range offers the widest possible choice for expansion control systems and responsible solutions for civil and commercial structures.

Building upon their bridge engineering expertise, and their knowledge of seismic movement, structural behavior and vehicular loading, Watson Bowman Acme are able to provide high quality, high performance expansion control systems that last for the ever-increasing performance demands of the parking structure market. Parking and Stadium structures also require the same high-performance of the architectural expansion joint with the added requirement of aesthetics, water tightness and fire protection for areas in and around luxury boxes, stair towers, and public use areas within those structures. Add to this, requirements for seismic management and sustainability of the structure, and you need the engineered expertise of Watson Bowman Acme to ensure all project requirements are met – both now and into the future. These are world-class solutions expected of a BASF company.

Representatives from both RAB and WBA will be on hand at the exhibition to discuss and demonstrate the latest in expansion joint technology.

Wabo®WeatherSeam is a weather tight seismic expansion control system for interior and exterior walls and ceilings. An optional secondary moisture barrier is available for exterior applications. The colored elastomeric seal completely covers the supporting aluminum frame creating a functional and attractive joint.

Wabo®Crete StripSeal

The Wabo®Crete StripSeal expansion joint system is a unique and superior joint system used in the construction and rehabilitation of expansion joints for bridges and parking decks. When poured into the blockout, Wabo®Crete II flows and completely fills any voids, spalls or irregularities forming a monolithic unit. The Wabo®Crete StripSeal system is well suited to high impact applications due to its durability and resistance to chemical attack in harsh environments. The rugged design of the system and Wabo®Crete II’s high bond capability to both steel and concrete allows the system to accommodate the high loads of vehicular traffic. Wabo®Crete StripSeal systems can accommodate a variety of field configurations along with multidirectional movements.

Wabo®ElastoFlex Parking

Wabo®ElastoFlex is a watertight continuous membrane system for joints with movements up to four inches in parking decks, loading docks, elevated roadways, entrance ramps, and other vehicle and forklift traffic areas. The system uses mechanically fastened EPDM anchor blocks with molded-in steel inserts to support heavy duty and high impact loads. The winged flap of the durable elastomeric seal is locked between the anchor block and concrete slab. A sealant bedding compound is applied between the winged flap and concrete slab to enhance the product's watertightness. The exposed surfaces are nonmetallic and skid resistant while resisting UV deterioration and most chemicals.


Wabo®FireFlex is approved to accommodate +/- 50% parallel lateral shear and multi-directional seismic movement. Additionally, Wabo®FireFlex is cycle tested to exceed ASTM E-1399 and is listed with Underwriters Laboratories for Class II and III movement classifications for standard and seismic lateral shear.
