TELUS Gardens is an exceptional $750-million, 92,903 m² (1,000,000 ft²) project featuring a 53-floor residential tower with 1,393.5 m² (15,000 ft²) of amenities, and a 24-floor signature office tower that will serve as TELUS Communications new National Headquarters in the heart of Downtown Vancouver. The building comes equipped with the most advanced entertainment and communications technology and is working towards Leadership in Energy and Environmental Design (LEED) Platinum designation for the signature tower and LEED Gold designation for the residential tower, with 425-green homes, making it not only one of the more stunning buildings in Vancouver, but also one of the most environmentally friendly developments.
Shotcrete was used for the structural walls in the below grade parking area. No external membrane could be used due to the inherent risk of tearing. Also, in order to work towards the LEED designations, traditional petroleum-based externally applied membrane was not an option.
To waterproof the impressive design, Kryton’s Krystol Internal Membrane™ (KIM®) admixture was used in the shotcrete application. 1,600 m³ (565 t) of KIM concrete was able to waterproof all six levels of below grade parking without the risk of damage to an external membrane, which also reduced the amount of shrinkage and cracking typically found in shotcrete. Also, Kryton’s Waterstop System™ was used for construction joints, pipe penetrations and control joints in all below grade exterior wall joints, ensuring a watertight foundation to an impeccable building.
As of writing, TELUS Gardens is currently experiencing dry and dusty conditions where KIM Shotcrete was used, and on its way to all LEED designations.
