A new engine testing structure at the Ford Dunton Technical Centre required a flexible, water tight, acoustically sound expansion joint system. Wabo®HSeal was selected by the client and then installed by RAB. As well as the features above and being able to accommodate vertical, horizontal and skew movements, HSeal has excellent acoustic properties too – not only keeping water out but keeping noise in. It is ideal for car parks, plazas, stadiums, and waste water facilities. RAB also offer a bridge version of the product called FS Bridge Seal.
