Princes Wharf Sewage Pump Station: Auckland

Xypex Admix C-1000NF was added to the concrete for the precast walls, central tower and in-situ cast floor slab of this large pump chamber.

The chamber is subject to seawater pressure externally and contains sewage prior to being pumped to the Manukau Wastewater facility for treatment.

140m of Kuniseal C-31 waterstop was used to seal the in-situ cast stitch joints and floor/wall construction joints to make the structure watertight.
