12. Introducing Easy-Cure
Kryton has recently unveiled a cost-effective curing
compound that meets the requirements of the American
Society for Testing and Materials (ASTM C309). Easy-Cure,
the new membrane-forming liquid curing compound, helps
to properly cure concrete by slowing the evaporation of water
from freshly finished concrete. The strength, durability and
water-resistance of the concrete are enhanced by minimizing
cracking and promoting hydration – the chemical reaction
between cement and water.
The product works hand-in-hand with other Kryton
technology such as the Krystol Internal Membrane (KIM)
waterproofing admixture system. Easy-Cure helps to decrease
the permeability of concrete and retains the internal water
necessary for maximizing KIM crystal growth.
As a waterborne compound, Easy-Cure can be easily sprayed
or rolled onto the surface of concrete after finishing is
complete. It is available in clear or white pigmenting to reduce
heating from the sun and help with the application process. Easy-Cure™ meets the requirements of the American
Society for Testing and Materials (ASTM C309)

Marina Bay Sands Integrated Resort and Casino, Singapore
Located at Marina South in Singapore, Marina Bay Sands resort will feature Singapore’s
first casino, three hotels, theatres, a waterfront promenade and a convention centre.
Construction on the sprawling 560,000 square metre site began in November 2007 and
called for more than 50,000 cubic metres of concrete to be waterproofed with Kryton’s
KIM admixture. It is one of the most extensive single-site waterproofing projects
undertaken by Kryton to date and is due to be complete in late 2009.
Big Box Mega Store, Singapore
Spanning almost 27 football fields, the Big Box Mega Store located in Jurong East
in Singapore is using Kryton’s waterproofing products for all below-grade surfaces.
Approximately 15,000 to 18,000 cubic metres of concrete will be waterproofed with
KIM admixture. Construction on the store is under way and due to be complete in
2009. When finished, the store will contain retail space, warehousing and offices.
Scotts Square, Singapore
Scotts Square, in the heart of the renowned Orchard Road shopping district of
Singapore, is a two-tower condominium and retail space complex that will use
Kryton’s KIM admixture in the four floors of the project that are below ground.
The 43-storey towers will include residential and office space, and is expected to be
complete in 2011. When complete, sculptures by Henry Moore, Dale Chihuly and
Salvador Dali will grace the grounds. Construction began in September 2008.

15. KK Times Square – Phase 1 and 2, Kota Kinabalu, Sabah, Malaysia
KK Times Square is located in the heart of Kota Kinabalu, a popular tourist destination
near Borneo. The project’s first phase of 12 blocks of business suites, shops, offices
and retail outlets, was completed in 2007 and used a combination of Kryton’s KIM
admixture, T1 T2 surface treatment and Krystol Waterstop System from top to
bottom. In light of the project’s proximity to Sutera Harbour in the South China
Sea, the project called for a waterproofing system that could withstand constant
hydrostatic pressure, protect against the corrosion of steel reinforcements and
withstand the uncompromising heat and humidity of Sabah for many years. More
than 100,000 kilograms of KIM admixture in 15,000 cubic metres of concrete were
used in the basement slabs and elevator pits of KK Times Square Phase One. Kryton’s
waterproofing products were also used in the elevated car ramps, pedestrian walkways,
retaining walls, drainage areas and rooftops. With that proven success, Kryton’s
products are also being used in Phase Two, which is now under construction.
Phase Two is a 15-acre development comprising a five-star hotel, shopping complexes, exhibition facilities, restaurants, cineplexes,
two prime office towers and condominiums. Kryton is waterproofing another 15,000 cubic metres of concrete for this phase. When
complete, KK Times Square will be completely waterproofed with Kryton’s Krystol Waterproofing System.
Zenith Corporate Park, Kuala Lumpur, Malaysia
Zenith Corporate Park is designed to be a leading business centre for Kelana Jaya in
Kuala Lumpur. Kryton has been actively involved since April 2008, waterproofing
more than 15,000 cubic metres of below-grade surfaces. In total, over 80,000
kilograms of KIM admixture will be used. The nine-acre project is expected to be
completed by mid-2010 and will be Kryton’s flagship project in Kuala Lumpur.
