Raymond Brown were tasked with the development of 2 new wet docks, 3 construction halls and a four-storey office complex.
The Overall Objective
The expansion involved the creation of a new sea wall, which required a cementitious solution with low heat of hydration, high early strength, good long-term strength gain and, because of the aggressive marine conditions, enhanced resistance to sulphate and chloride ingress.
A Siltbuster pHD was quickly deployed to site on a pallet, and operated in conjunction with 2 standard builders skips lined with plastic. Trucks would back up and clean their chutes into 1, while the waters were over pumped and treated in skip 2. This low cost solution handled multiple washdown events every day and ensured no high pH water was discharged off site.
