Xypex Case Studies – Northshore Hospital Car Park
Project Description
Northshore Hospital and its car park is located beside Lake Pupuke, and being less than 1.5km from Takapuna Beach, so is exposed to wind-driven chlorides from the Hauraki Gulf. The addition of Xypex Admix to the car park concrete is expected to increase the design life expectations of the structure, by resisting chloride penetration through the 40MPa concrete and imparting its renowned self-healing ability for fine cracking. The top deck of this car park was post tensioned over 3 large pours, with 4,822kg of Xypex Admix C-1000NF added to the in-situ cast concrete slab for waterproofing and steel reinforcing protection. Two construction joints that crossed the level 6 deck were waterproofed using 112m of Kuniseal C-31DS Waterstop and Xypex Concentrate. Concrete test cylinders taken during the Level 6 deck pours were routinely achieving between 50-55MPa.
