Supreme has customised solutions for various segments in the construction industry.
The term expansion joints refer to the isolation joints provided within a structure to permit the separate segment of the structural frame to expand and contract in response to temperature changes without adversely affecting the structural integrity or serviceability.
The need for expansion joints in buildings may be determined initially on an empirical basis. If results are deemed by the designer to be too conservative or if the empirical approach is not sufficiently comprehensive to be applicable to the type of structure being investigated, a more precise analysis should be undertaken. Meanwhile, the subject of expansion joints in the construction of concrete highways has been considered controversial by many; however, there are really only a few important areas of disagreement among those who understand the basic engineering principles involved.
Anyone familiar with the coefficient of expansion of concrete realises the necessity of providing adequate expansion joints; also the necessity to eliminate intermediate cracks by creating planes of weakness to predetermine the location of contraction cracks. In their (contractor) zeal to lower the cost of concrete highway construction, some engineers have been using only sawed joints, completely disregarding the important function of properly spaced through expansion joints. Since, roads and buildings, being the second largest activity in the economy after agriculture, the role of expansion joints in these areas has become critical.
To bridge the gap between cost effectiveness coupled with high quality, The Supreme Industries Ltd, Construction Accessories Division has developed customised solutions specifically for the construction requirement of various sectors. SupremeÂ´s DURAboardHD100, DURArods and DURAsilstrip are the three aces which cater to the need of building or road structures, assuring the structure with great bonding. To start with, SupremeÂ´s DURAboardHD100 is a crossed-linked, pre-moulded, high performance joint filler board which is readily compressible and ensures low load transfer. This structural expansion joint application can be used in concrete brick and block work; it also helps isolation to fill its gap and work as a backup supporter for sealant. Another feature of the product is it can be used for the expansion joints in concrete highway, taxi tracks and most importantly in airport runway.
How will buyers benefit? The product comes with closed cell, has excellent chemical resistance, thermally stable (ranges from -40Â¦ C to Â¦ C), most importantly, is bitumen free, rot proof and bacteria resistant. DURAboardHD100 is available in thickness ranging from 8 mm to 100 mm sizes.
In addition, SupremeÂ´s DURArods have some more benefits to offer to its buyers. The product is a closed-cell polymer based circular profile which ensures stronger bonding of sealant with masonry, aluminium or other substrates and helps to maintain desired thickness of sealant at the jointÂ´s centre. Importantly it does not bond with cold applied sealants. The product can be used in applications like pre-cast panel joints, coping joints, contraction joints, expansion joints, glazing joints as well as isolating joints, and window and door frame parameters.
