  4. 4. The s ofIntegral Crystalline Waterproofing A lthough crystalline waterproofing technology has been around for more than 50 years, it is still considered “state-of-the-art” and has only recently been embraced by the construction industry as a superior replacement for conventional membranes. Used in virtually every country around the world, integral crystalline waterproofing has been repeatedly and successfully tested.Though concrete looks like a dense, rock-hard material, it’s actually full of pores, capillaries and micro-cracks invisible to the naked eye.

  6. 6. A Lesson in Shotcrete from San Francisco Recently, shotcrete has been gaining popularity along North America’s West Coast. Southern California, for example, has seen a dramatic increase in the certification of shotcrete nozzlemen to support the demand of existing and future projects. Developments are now looking to shotcrete to meet deadlines and budgets. In addition to providing waterproofing for the perimeter walls of the five-level parking structure, Kryton products were also used to waterproof the foundation slab and elevator pits. The cold joints between the slab and wall were treated with the two product Krystol waterstop system for a completely watertight San Francisco’s newest landmark residential condominium foundation.

  12. 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)Hot Weather Concreting ChallengesWhile many industries may flourish finishing difficult, can reduce the in warm climates, high temperatures overall concrete strength, and increase and humidity create many challenges cracking. An effective solution is for the construction industry. Hot, to use an admixture to slow down dry weather can lead to excessive setting times and reduce shrinkage surface moisture evaporation and cracking.during concrete curing. This can cause shrinkage, cracking, finishing Concreting in warmer temperatures difficulties and reduced concrete calls for extra care and makes the strength in buildings – problems that curing process even more essential. must be mitigated from the onset of Proper curing practices protect and throughout construction. concrete by maintaining a satisfactory moisture content and temperature.

Warm weather impacts the concrete strength The result is a positive outcome for setting time of concrete by causing builders and those who live and work it to dry too quickly.

Curing Concrete (ACI 308). Easy-Cure™ Without Easy-Cure™ What is the benefit of using a curing compound over other curing methods? Curing compounds are preferable under many conditions due to their ease of use, practicality and low cost. In addition to assuring a consistent quality cure, curing compounds are especially useful in situations where water curing is not feasible. For example: In areas where water is not accessible or available A curing compound helps to reduce the rate of evaporation In remote areas where there are increased labour of water from the concrete surface. costs associated with travelling in and out of the job What are some curing methods? siteAccording to the American Concrete Institute’s Standard Practice for Curing Concrete (ACI 308), In windy or hot areas where the evaporation of curing should be continuous for a minimum of seven water is excessivedays or until 70 per cent of the specified strength has been attained.

  15. 15. KK Times Square – Phase 1 and 2, Kota Kinabalu, Sabah, MalaysiaKK 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, MalaysiaZenith 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.
