Auckland University School of Business is a huge structure with a basement car park. The deepest two levels of the basement car park were composed of in-situ cast 300mm thick walls, dosed with Xypex Admix C-1000NF as the only concrete waterproofing.
Kuniseal C-31 Waterstop was applied to all associated construction joints and covered with a slurry of Xypex Concentrate. Kuniseal was also used at select levels higher up where required. Stage 1 of the basement was completed via Marin Construction, while Stage 2 was executed through Dominion Constructors.
1,893kg of Xypex Admix C-1000NF was added to 30MPa concrete supplied by Firth, with a total of 2,940m of Kuniseal placed under 360kg Concentrate.
The final car park is clean, tidy and very well presented, with no sign of leaks after several years.
