| 11 REGIONAL DEVELOPMENT Sansom - 50th Anniversary Sansom has grown into a nationwide provider of specialist services, trusted by leading contractors, developers, and property owners for some of the country’s most challenging and highprofile projects. Primary Contractor: Icon NZ Waterproo ing Contractor: Sansom Architect(s)/Consultant(s): Ashton Mitchell Developer: Cedar Paci ic Building Operator: UniLodge New Zealand Development Manager: McConnell Property Project Overview The project involved the use of nearly 2000 square metres of ARDEX WPM 196 and ARDEX WPM 195 Below Grade Tanking membrane. Additionally, over 100 lineal metres of marine grade hydrophilic WPM 1955 waterstop was detailed around the piles on the foundation. One of the key highlights of this project is how the ARDEX membrane was integrated into the existing heritage-listed building, Campbell House. Ensuring a successful tanking system while preserving the historical façade structures was vital for this project. Challenges and Solutions The project faced several challenges, but through close collaboration and teamwork, these were successfully overcome. One of the major challenges during construction was water build-up. Icon, the main contractor, had pumps running continuously to remove the water, allowing Sansom, the waterproo ing installer, to lay the tanking system e ectively. The ARDEX Technical team worked closely with the waterproo ing installer (Sansom), architect (Ashton Mitchell), and main contractor (Icon) by providing on and o -site support. Key Component Products · ARDEXWPM 195: A high-performance, Sand Finish SBS bituminous compound with excellent cold lexibility (-20°C) and adhesiveness, suitable for all climates and resistant to chemical attacks.
