Technically, waterproofing is “the treatment of a surface or structure to prevent passage of water under hydrostatic pressure”. It is critical yet neglected issue when it comes to finishing works of a structure. One has to understand that the basic purpose that gets served by waterproofing is the increase of service life of the structure, by preventing the corrosion of the steel of the structure. The importance of waterproofing, especially in Industrial areas and in manufacturing units can’t be neglected as machineries and materials of corers of value are at stakes.

Today, the world’s 60 per cent of waterproofing works are getting executed by using APP/SBS modified membrane. The method not only saves labor cost but also there is no possibility of manipulation from contractor’s end while executing the work as it is a pre fabricated material.

These membranes have wide range of applications like on residential and industrial roof tops and deck slabs, basements, reservoir, tunnels, gardens, podiums, bridges and flyovers.

The easy application is the reason why it has got a wide acceptance across the globe. Following is the method of application of APP/SBS Modified bitumen based polyester reinforced waterproofing membrane:
• Clean the surface thoroughly to make it smooth and free of any foreign material.
• Apply a coat of Supreme Super Primer @ 0.3 litres per sq.m. and allow it to dry. In areas of high humidity, the primed surface should be left over-night.
• Laying Supreme Super Shield Membranes on the primed surface, start laying of membrane at lowest point of the slope roof ( or any other structural member) and progress to the higher point. Unroll using a LPG torch and applying uniform pressure with a roller/wet cloth to ensure to remove entrapped air, if any.
• Heat both layers of membrane at the overlap and use round tipped hot trowel to seal overlap. Excess compound should be smoothened and pressed into seam using hot trowel. Overlap joint shall be provided of 75 mm in longitudinal direction and 100 mm in transverse direction.
• Super Shield Membrane is also available in self adhesive sheet hence no torching is required.

If work is executed properly, we give the guaranty of 5 to 10 years depending upon the thickness of the membrane used.
