The Project 

Project Overview:  

Toi Manawa, the brand-new Performing Arts Centre at King’s College encompasses the school’s values for the best all-round education while endorsing existing programmes and introducing new art forms to the students. The centre includes a specialist theatre that features sound, lighting and set infrastructure, an orchestra room, a rock room, rehearsal rooms, three teaching spaces and a specialist dance and drama space.

 Challenges:  

A key challenge for this project was the contaminates in the soil on the building site, especially around where the specialist theatre would be. This soil had a layer of peat that was causing a reaction leading to carbon dioxide (CO₂) gas being released. This theatre will house top of the line equipment so needs to be waterproofed to the highest standard while also not being affected by the contamination. Onsite water control was also a challenge due to the depth of the water table and the exposure to the elements during construction.

Allco Solutions:  

Specialist Theatre: The unique requirements of this space meant that Coreflex was the best option to waterproof this section of the project. Providing the ultimate waterproofing protection, Coreflex consists of a thermoplastic membrane integrally bonded to a proprietary Active Polymer Core (APC) layer. Engineered to resist high hydrostatic pressure and groundwater contaminants, it sets the standard for waterproofing membrane strength, durability and performance.

Under Slab: The Volclay Voltex membrane was used to fully encapsulate under the slab, ground beams and lift pits along with a full range of accessories including Waterstop RX, Aquadrain, Waterstoppage, Bentoseal, Cetseal and Cetcoat.

Podium and Gutters: The Casali torch-on two-layer system was utilised for the podium and gutters to ensure waterproof roof and decks as well as a smooth transition to the below ground waterproofing membranes.

Execution and Outcomes:  

The combination of Coreflex, Volclay and Casali ensured a complete and cohesive waterproofing solution for this project. The use of Coreflex to address the onsite challenges meant specific training was required and expertly completed by Approved Applicators CCR Waterproofing. Persistent use of water pumps and meticulous waterproofing were essential to manage the environmental challenges and construction-related water exposure during this project.

This project was seamlessly executed by CCR Waterproofing, with excellent collaboration between them, Main Contractor Aspec Construction, Facade Engineers Oculus and the Allco Technical Advisory Team. This collaboration and communication ensured all on site requirements and challenges were handled in a timely manner to provide a fully watertight Performing Arts Centre for current and future King’s College students.
