50 Albert St, Auckland

50 Albert Street, developed by Mansons TCLM, is a landmark office building located in Auckland’s city centre, on the former site of the NZ Herald building. This 32,448m² development, which includes prominent tenants such as Spark and Milford Asset Management, exemplifies the “flight to quality” trend in office spaces. With a focus on sustainability, the building is targeting a 6-Star Green Star rating and Platinum WELL rating, setting a new benchmark for environmental and wellness standards in New Zealand. The building’s design includes a four-storey podium, flexible office spaces, a planted terrace, and high-performance curtain wall cladding.

WATERPROOFING SOLUTION

For the plant rooms, Mansons TCLM specified Neuchatel Mastic Asphalt, a highly durable waterproofing product, chosen for its resilience and ability to withstand heavy foot traffic and construction wear, unlike other membranes that are not trafficable and lack the same strength.

Our team at Asphaltech has been installing Neuchâtel Mastic Asphalt on Mansons’ plant room projects for over 20 years. At 50 Albert Street, the plant room covers an expansive 800m², including plinths up to one metre high. The waterproofing was applied using a traditional trowel method, with a solar coating added for extra protection. The use of Neuchatel Mastic Asphalt ensured minimal damage during construction, leading to cost-effective long-term performance. An Independent Leak Detection (ILD) report showed only minor issues, a testament to the quality and reliability of the waterproofing system and our installation team at Asphaltech.
