There is a Very High Demand for Waterproofing Membranes  in India

Name some of the top projects you have been associated with since last year?
NHAI, Airports, Power and many more infra-structural projects in India.

Are you planning to offer any new products soon?
Supreme has always been offering cost effective yet resilient solutions to construction industry. All our products have been developed after continuous interaction with our customers, market analysis and understanding thoroughly the needs and changing demands of the new generation structures. We are now introducing DURAmembrane – A high performance waterproofing membrane.

Tell us more about DURAmembrane.
Since past few years, there was a continuous demand from all our satisfied customers to develop waterproofing solutions to solve the leakage problems in their factories and offices. They were not very pleased with the current waterproofing systems available in the market. Hence about one year back, our R&D team started working full-fledged on this project to develop a composite of various polymers cross linked and fused resulting in this exclusive high performance membrane.

DURAmembrane is a new offering in the portfolio of competent and DURAble products of the Construction Accessories Division. DURAmembrane is a new generation, cost effective solution for waterproofing of basements and roofs. It is a versatile material, capable of retaining the dryness of concrete, masonry, metal and wood structures and is resistant to salts, alkalis, and most acids. It is offered as a quick and easy-to-apply system, ensuring hassle-free maximum productivity. Supreme is the only manufacturer of this type of waterproofing membrane in India. It can be used for applications like - concrete roof waterproofing, basement waterproofing and also waterproofing of bathrooms & terrace gardens. DURAmembrane can not only be used in new constructions but also at the time of repair of a structure.

What are the striking features of this product against the bitumen based membranes available in the market?
DURAmembrane is a high performance, composite polymeric membrane which is durable and lightweight. It is non-deteriorating, puncture resistant and is available in length up-to 50 meters.

Talking about evaluation against bitumen based products – we all know that bitumen disintegrates after contact with water. Further, over a period it catches fungi and also starts melting during summer, thus lowering its puncture resistant strength.

The striking feature of DURAmembrane is that it has a very good puncture resistance of 199 N (Test method - ASTM E154: 1999) and being polymer based, it won't deteriorate also over a long period.

Is DURAmembrane cost effective in comparison with other polymer based membranes and waterproofing chemicals? If yes then how?
Very much. None of the waterproofing solution systems provide any added advantage except waterproofing whereas DURAmembrane apart from being 100% waterproof is also an excellent insulating material.

Any roof treatment has to contend with the unrelenting assault of surface expansion and contraction due to daily/seasonal temperature changes. Other treatments have a tendency to absorb moisture and conduct heat. DURAmembrane does not absorb water at all. Its 'K' value does not deteriorate. Its inherent closed cell structure ensures truly effective thermal insulation and waterproofing – virtually for a life time.

Will DURAmembrane stand up to the test against the extreme climatic conditions in India? Is it stable and resistant to wear and tear?
Climate of India is most unreliable. India being a tropical country has diversity in climates. Some regions in India have hot tropical weather while some parts have heavy monsoons.

When the ambient temperature varies between 0 to 50ºC, the overlying treatment is called upon to withstand a corresponding variation of – 1 to 65ºC. DURAmembrane meets these challenge with complete and effortless ease and can withstand temperature ranging from – 40 to 115ºC.

Roof treatments have to withstand more than just surface expansion and contraction. Like structural movements or the setting of the building with time. Sudden drops in temperature results into thermal shocks. DURAmembrane has excellent elongation and tensile strength that enables it to take all movements in its stride. It is fracture, crumble, shatter and abrasion proof and resistant to most corrosive chemicals.

What is the demand for a water- proofing membranes in India?
Very high. With monsoons come problems like leakage, seepage in roofs, walls, basements, bathrooms etc. in buildings - commercial / residential and factories. After every shower of rain, structures tend to expose their limitations and flaws. The monsoon rains actually test the building with showers and reveals the defects that are not normally observed during sunny days. Leakage and seepage in roofs, walls, bathrooms and basements are some of the typical problems. Hence, to shield from the huge losses incurred due to the rains, people are determined to pay attention to the problems prior to the next rains.

With the current focus on constructing green and sustainable buildings, what is your Company's contribution in this?
We have accomplished very high standards in manufacturing, and we firmly believe in the protection of our environment. The Supreme Industries Ltd. follows the philosophy of S.A.V.E. – Supreme Always Value Efficient. Applied intelligence and innovation, enabling cost-effectiveness and precision in delivery are the drivers of this belief. Every requirement is understood meticulously, various solutions are deliberated upon and the most appropriate one is selected and implemented flawlessly. Trust and reliability are the cornerstones of our delivery promise. Whatever be the value, whether its superior protection, energy saving insulation or durable and long-lasting solutions in the civil / thermal insulation industry our customers are assured of a solution from Supreme. Because at Supreme, every single solution we create is guaranteed to be Value Efficient.

What is your vision for this product?
This is a first of its kind of concrete roof and basement waterproofing product, specially designed to withstand the hot and humid Indian conditions. Our membrane is going to solve problems and reduce huge losses arising out of water leakage. The entire construction industry will benefit from this product.
