KK Times Square

Dubbed Kota Kinabalu’s largest ever urban commercial project, KK Times Square is a sprawling, 93,000 square meters (23-acre) development designed to accommodate the city’s expanding commercial activities. Comprised of a combination of office and retail facilities and public spaces, KK Times Square offers shopping, dining, entertainment and leisure activities for Kota Kinabalu residents and the city’s growing tourism industry.

KK Times Square was built in two phases. Phase One is an ultramodern, eight-acre development of 12 five, six and eight story buildings with a total floor space of more than 60,000 square meters (645,000 square feet).

When selecting a concrete waterproofing system for Phase One, the project team had several key concerns. Given the project’s scope and timeline, affordability and ease of application were critical. Knowing that some concrete waterproofing systems deteriorate over time, they wanted a system that would be long lasting, thereby minimizing future repair costs and inconvenience to tenants and their patrons. As the project was located next to the Sutera Harbour in the South China Sea, they needed a waterproofing system that could withstand significant hydrostatic pressure.

Solution

After considering several options, the project team selected the Krystol Concrete Waterproofing System. The Krystol system uses advanced integral crystalline waterproofing technology to transform porous concrete into a permanent, water-resistant barrier and provides a guaranteed defense against water damage and steel reinforcement corrosion.

By eliminating the need for external waterproofing membranes, the Krystol Concrete Waterproofing System saves construction time and costs. It provides maximum flexibility and can be used any time before, during or after the construction process. 

More than 55,000 kg (121,252 lbs) of KIM, and 7,250 m3 (9.483 cubic yards) of KIM-treated concrete were used in the basement slabs and elevator pits of KK Times Square Phase One.

In excess of 25,000 kg (55,115 lbs) of Krystol T1/T2 was used to the elevated car ramps and pedestrian walkways, drainage areas and rooftops around the 12 Phase One buildings.

And 2,400 m (7,874 ft) of joints in the retaining walls and basement slab-to-slab areas were treated with the Krystol Waterstop System.
