Company Profile - Supreme Industries

Bonding solutions

With expansion joints being critical to every construction project, Supreme Industries has been at the forefront of offering a range of customised solutions.

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 zeal to lower the costs 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 are the second largest activity in the economy after agriculture, the role of expansion joints in these areas has become critical.

 

SUPREME SOLUTIONS

Against this background Supreme Industries Ltd’s Construction Accessories Division has developed customised solutions specifically for the construction requirement of various sectors.  Supreme’s DURAboardHD100, DURArods and DURAsilstrip are the three aces which cater the need of building or road structure, assuring the structure with a great bonding.

 

PRODUCT FEATURES AND BENEFITS

 To start with, Supreme’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.  The product comes with closed cell, has excellent chemical resistance, is thermally stable (ranges from -40° C to +70° C) and more importantly is bitumen free, rot proof and bacteria resistant. DURAboardHD100 is available in thickness ranging from 8 mm to 100 mm sizes.

Supreme’s DURArod too has benefits to offer for 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 joint’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. Meanwhile, DURArods works as a back-up to sealant in structural glazing systems. The product is available from 6 mm to 60 mm size. As far as features and benefits are concern, it offers closed cell, hence negligible water or moisture absorption; excellent chemical resistance – inert to most acid and alkalis and cost effective space filler. It also allows unrestrained expansion and contraction of sealant while eliminating bubbling of sealant.

While DURAboardHD100 and DURArods can be termed as brother in arm bonding together, the next in line DURAsilstrip is bond breaker. The product is a closed cell, compressible polymer based material (paper) backed on one side as per IRC: 57-2006-6.3 and 6.4. DURAsilstrip ranges from 2 mm to 12 mm size. However, other sizes also available on request. The product works as a bond brakes between any cold applied sealant and fourth surface in contraction or expansion joints. This also works as a backup to cold applied sealants – to be precise – in concrete road. The features and benefits of the product is more or less in line with the other two, however, it have compressible and flexible joint movements along with non-staining, which means it does not disintegrate.
