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, talks about the company’s star brand, ‘DURAboardHD100’
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 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 resulting in developing cracks and may at the end could break.
Also, in the winter the harsh cold temperatures would make the materials contract in nature and this would also result in disastrous circumstances.
DURAboardHD100 (formerly SILflex/Capell 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 or sheets form. It is very light weight.  This makes it very easy to handle and install. Being polymer based, it is rot proof and bacteria resistant.
