High Performance, Compressible Filler Board for Expansion Joints – DURAboardHD100

The infrastructure story is set to open a new chapter if the Central Government goes ahead with its new scheme of Ultra Mega Road Projects (UMRPs). The sheer size of each UMRP — Rs.20,000 crore — envisages a massive transformation of the Indian road landscape. Under the UMRP, developers will be allowed to collect fees from users of these roads for a period of up to 30 years as well as develop real estate projects alongside the highways. The additional incentive to develop real estate is the key ingredient to make these projects remunerative and attractive for large corporations.

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, General Manager, Construction Accessories Division, the Supreme Industries Ltd. shares his views 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" he said. "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," he added.

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 is readily compressible low load transfer joint filler is required. Its excellent recovery 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 and 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
• Non-staining

DURAboardHD100 can be used in:

• 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.

It is massively used in PQC and various structures for NHAI, AAI, real estate and british specification & specification for highways works clause 1015.

"Some government organiza- tions 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 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," said Ajay Mohta.

Nearly Rs.15,099.84 billion is likely to be invested into the infrastructure sector over next five to ten years which would provide a huge boost to the construction industry as a whole.This will provide increased opportunities for organizations like Supreme Industries that play an important role supporting the construction industry.
