Construction World – February 2008
Skyline Contractors Pvt Ltd was able to cut down on costs and save 8-10 weeks of construction time on a five-star hotel in Gurgaon using Integral Crystalline Waterproofing technology.
Quality and aesthetic value of a building structure meanseverything in the hospitality industry. In the business district of Gurgaon, a new five-star hotel was to be constructed starting November 2004, with plans to have the facilities operational at the earliest. Today Hotels Pvt Ltd, developers of both residential and commercial real estate properties, envisioned building the finest, most modern business hotel with features such as 37-inchplasma TVs with a Bose music system, individually-controlled air conditioning and the Club Lounge, one of the largest meeting spaces in Gurgaon.
The 234-room hotel includes 15 suites, a below-grade extended basement and a swimming pool. In order to achieve their goal of opening the hotel at the earliest, Today Hotels needed a complete waterproofing solution that could be easily installed and not delay the construction process; yet provide proven and permanent results.
Now, Today Hotels have a very high quality of specification standards in all their developments. The architect, Rajendra Kumar Associates, had used Kryton’s crystalline waterproofing products in previous projects, and decided to specify the products again in the Crowne Plaza Today Hotel. A wide range of Kryton products were used in the below-grade foundation, swimming pool, joints and external plaster.
Krystol Internal Membrane™ (KIM®), a cementitious admixture, was used in all below-grade, walls and theswimming pool foundation and walls. Because KIM® can be mixed right at the site into the transit mixer, it required no installation time and also reduced the risk of human error. Krystol T1, a surface-applied slurry, was used in all the floor slabs and sunken slabs of the basement. Cold joints were treated with Krystol Baricote™ , a fast-setting waterproof grout. In the external plaster of the hotel, Krystol Mortar Admixture (KMA) was used to protect the building from dampness accumulated during rainfall.
All these products use Integral Crystalline Waterproofing (ICW) technology to provide the world’s only permanent, self-sealing, cur rosion-free concrete waterproofing products. Unlike conventional waterproofing methods which involve applying a coating or membrane to the concrete surface, ICW technology perm nently seals concrete through a unique chemical reaction. When added to the concrete, crystalline chemicalsreact with water to create long, narrow crystals which plug the natural pores and capillaries of the concrete, blocking the movement of water. It also reacts with incom ing water to self-seal the cracks that inevitably develop in concrete, protecting structures against water and contaminants that can weaken or destroy concrete and corrode steel reinforcement.
By using the wide range of Kryton’s waterproofing products, Skyline Contractors Pvt Ltd was able to cut down on costs and save 8-10 weeks of construction time, allowing the hotel to be fully open and operational in December 2006. By adopting the KIM® admixture into several areas, no extra time or labour was required for post-construction waterproofing. Similarly, where the surface applied Krystol T1 was used, the time application time was consider ably less than the installation time of a conventional waterproofing system. The developers and architects rest assured knowing that neither quality nor results were compromised by using a proven product line that could save them time and money.
