Supreme Industries Ltd.
In the 12th plan (2012–17) period, the central government is expecting a massive $1 trillion investment into infrastructure development providing the civil construction industry with a major boost. The importance of civil construction industry can be gauged from the fact that it is the second largest economic activity after agriculture. With estimated investment into construction at 11% of India's Gross Domestic Product (GDP) – it holds huge untapped potential. Around Rs.15,099.84 billion is likely to be invested into the infrastructure sector over the next five to ten years in segments such as power, roads, bridges, city infrastructure, ports, airports, telecommunications – this is expected to give impetus to the construction industry nationwide.
The Supreme Industries Ltd., founded in 1942, pioneered many path-breaking products in the country and became trendsetters in plastics products by introducing many advanced solutions for various applications and industries. Ajay Mohta, talks to NBM&CW about the company's star brand, DURAboardHD100.
"The Construction Accessories Division of Supreme has developed customised solutions specifically for the construction requirements of various segments. All our products have been developed after continuous research and understanding the needs of the changing demands of the new generation constructions. Many of these products have been pioneered by Supreme.
A case in point is the creation of a low compression set filler board (DURAboardHD100) especially for expansion joints application, to replace less effective bitumen board based solutions." The Division offers new generation, better alternative products to conventional materials like rubber, metals, and wood, thus being cost effective. The 'DURA' range of products are manufactured from virgin raw material and we do not use any CFC / HCFC gases. At every stage of the manufacturing process, a stringent quality check methodology assures the reliability of the products."
An expansion joint is an assembly designed to safely absorb the heat-induced expansion and contraction of various construction materials, to absorb vibration, to hold certain parts together, or to allow movement due to ground settlement or earthquakes. Throughout the year, building faces, concrete slabs, and pipelines expand and contract due to the warming and cooling effect through seasonal variation, or due to other heat sources. If expansion joints were not implemented in bridges, building, highways etc. the intense heat in the summer would expand the metal, brick, or concrete materials in a structure and the structure would have cracks and breaks in it. Also in the winter, the harsh cold temperature would make the materials to contract (come together) and this would also result in disastrous circumstances.
DURAboardHD100 (formerly SILFLEX/CAPCELL HD100) is an exclusive compressible filler board specially designed to be used as expansion joint filler in concrete brick, block work and isolation joint, where readily compressible low load transfer joint filler is required. Its excellent recovered property makes it the most suitable product for this application.
DURAboardHD100 is a high performance, pre-moulded compressible filler board, closed cell joint filler material available in the board / sheets form. It is very light weight. This makes it very easy to handle & install. Being polymer based, it is rot proof & bacteria resistant.
The striking features of DURAboardHD100 are:
- Bitumen free - can be cut in any size with a normal knife
- Excellent recovery of 95% after compression up to 50%
- Polymer based – hence it won't deteriorate also over a long period
- Resilient and does not distort under normal load from wet concrete
- Expansion joints in building, concrete structure
- Expansion joints in concrete roads, parking areas, industrial flooring etc.
- Joints in bridges, decks, water retaining and water excluding structures etc.
- Isolation joints in machine foundation.
"Some government organizations still hesitate to use the new generation products and follow old specification of using bitumen based boards and cork sheets which disintegrate over a period of time. Bitumen board can absorbs water and hardly recovers once compressed - it defeats the purpose of application. It absorbs water and oozes bitumen thereby staining the structure. Supreme has a number of satisfied customers (government, semi-government and private) who have stopped using and recommending bitumen boards/ corks sheets after understanding the benefits of DURAboardHD100" concludes Mr. Ajay Mohta.
