RBS Global HQ

Various options were looked at with regard to the waterproofing of the in situ concrete as the different areas had different requirements of grades to BS 8102:1999. Car parking was to be a Grade 2 environment with all the other areas being enhanced to Grade 3 (a totally dry environment). Xypex was chosen for its ability to self seal cracks up to 0.4 mm – thus allowing pours of any size to go ahead. Not only was Xypex Admix waterproof concrete used in the substructure and the swimming pool but some of the Xypex remedial waterproofing products were used to eliminate water ingress problems where a membrane had failed.
