In November 2017, Concrete Canvas® GCCM (CC) was used to cover ballast fill materials in a steel tank cofferdam in Hong Kong. The cofferdam had been temporarily constructed in the sea off the site of a new highway which was being constructed along the coast of Junk Bay. As an environmental protection requirement, a cofferdam was erected in the sea to enclose the entire construction site, within which the remediation took place. The cofferdam consisted of a series of sheet piles at the middle and large steel boxes at either end. Concrete Canvas was chosen to confine the fill materials in the steel tanks due to its ease and speed of installation.
A highway would be constructed on the reclaimed land joining Lam Tin tunnel to Tseung Kwan O, bringing an additional route from Kowloon city to Tseung Kwan O new town. The works were carried out by CRBC and Build King in a Joint Venture for CEDD (Civil Engineering & Development Department) Hong Kong, with consultation services from Aecom Asia Co., Ltd.
