Auckland, New Zealand

Long Bay Town Centre is a mixed residential and retail development. The major retail component includes a supermarket with basement car parking covered with a podium deck. The podium deck connects pedestrian traffic to a mix of residential medium high-rise apartments and smaller retail outlets including restaurants and bars.

Project Requirements

  • Basement tanking
  • Podium deck waterproofing
  • Balcony waterproofing
  • Vehicle traffic deck waterproofing
  • Concrete repair solutions
  • Joint sealing solutions


The main challenge was the podium deck waterproofing. The deck design included expanded polystyrene and light weight concrete to meet structural loading requirements. This in turn had a significant impact on the detailing and execution of the waterproofing of the deck.
