Partially underground carpark required robust waterproofing for the foundations and pile face due to the proximity to the marina.
The full Allco Volclay range in particular the Volclay Voltex SWR was chosen for this project due to its ability to handle the locational challenges of the site.
The Victory Christian Church and Convention centre is located at the heart of Auckland City sitting alongside Westhaven Marina. Following the construction of the new Victoria Park Tunnel, the design and construction of the new Victory Christian Church carpark began. The beautiful church and convention centre hosts a 2200-seat tiered auditorium, hosting many concerts, conferences and expos.
This was a complex project that also involved extensive remodelling of the administration building, which was connected to the carpark and partially cantilevered.
The three-level carpark for The Victory Christian Church and Convention Centre is a new build designed by DKO Architects and Jasmax to accommodate for the new motorway tunnel. Due to the nature of the new site being reclaimed land there were a lot of contaminates in the soil and vapours which were disturbed during excavation. The contaminated soil presented several challenges during construction that had to be managed. This partially underground carpark required robust waterproofing for the foundations and pile face due to the proximity to the marina.
The full Allco Volclay range in particular the Volclay Voltex SWR was chosen for this project due to its ability to handle the locational challenges of the site. Voltex SWR is designed for use on sites exposed to salt water and projects that require additional chemical resistance, extremely low water vapour and gas permeability. The vapours released during site excavation required protective equipment and contaminate suits to be worn during construction. The versatility and ease of installation of the Voltex SWR allowed it to be installed while wearing this extra equipment and allowing the foundations to be protected from the gas permeability once installed. In order to further minimise exposure to the evacuated vapours industrial ventilator fans were installed on site.
The project construction ran through a New Zealand winter with significant rainfall which required a temporary dewatering solution throughout construction. The benefit of using a membrane such as Volclay Voltex was evident with its ability to swell when hydrated to seal and prevent against future leaks, once confined; this led to no leaks post construction. This project had a pile face with very large thickenings to “beef up” the foundations which were also waterproofed with the full Cetco Volcay range.
The carpark design was complex with a pile face that was a wet wall and an internal block wall that acted as a façade. The carpark was designed to make future allowances for two levels of administration offices to be built on top.
Allco Approved Applicators, MPM Waterproofing completed a great installation on this challenging project facing unusual working conditions working closely with the contractor and Allco and the TA Team.
