Deep Inside the Crux!

Construction chemical industry although a niche domain in a wide spectrum of construction industry, it’s a largely dependent source in architecture and constrution field. Dr Sanjay Bahadur, Global CEO of , industries, shares the insight of this industry’s future prospect which is growing like Topsy, with Apoorva Nandish


Today’s construction work is progressing thick and fast. In this context, how does Dr.Fixit cater to waterproofing of high-rise structures (roof-top landscape amenities and external façade)?
With space shrinking across Indian cities, land prices rising high-rise buildings are today more of a realistic option than just being an ornamental icon. But high-rises have their own set of problems such as increased exposure to various weather elements and therefore being more prone to cracks or other damages. This leads to water leakages which are more challenging and expensive to rectify due to higher heights involved. It is therefore best to adopt preventive measures and utilize the best available technologies in cases wherein the damage does occur.

Very little water and moisture can seep through a high-strength, dense concrete, but low strength concrete that is poorly fused can be quite permeable. Therefore, the first line of defence against water problems is the use of high quality concrete mixtures and good construction practices. Pidilite specializes in products that boost the properties of materials used and hence prevents water leakages.

Today, Dr. Fixit is amongst the most trusted brands in the Indian construction industry known for its innovation and pioneering solutions for waterproofing.  With the focus shifting from conventional methods to modern methodologies, we at Dr.Fixit offer a wide range of products that provide surface-wise solutions to satisfy diverse requirements during construction.

Dr.Fixit LW+ is an integral liquid waterproofing compound that reduces water-permeability of concrete. Waterproofing is a process that is designed to prevent water from penetrating the structure. Typically it is done in various layers and stages to create multiple barriers so that water does not seep into the structure. These layers form the ‘Building Envelope’ that waterproofs the structure. It is a specially formulated cement additive that increases the life of the building as a result of which there are no cracks, no rusting and no leakages. Moreover it makes concrete cohesive and prevents segregation. It improves the integral waterproofing properties of cement, concrete and plasters after curing, resulting in longer life of the building.

Dr.Fixit Roofseal is a revolutionary product for new terrace waterproofing that provides the end consumer with a comprehensive solution to leaking roofs and terraces. For proper and correct application of the product, Pidilite has trained waterproofing applicators across India on the usage of these products.

Dr.Fixit Newcoat Ezee is a two-coat waterproofing product for terraces. It is a hassle-free, economical and reliable waterproofing system which can be applied over the traditional brickbat coba and mud fuska. The best practice used internationally is to coat the terrace with elastomeric coatings and we at Pidilite have worked towards the same.

Dr. Fixit Blueseal is a unique Spray Applied Polyurethne Waterproofing System with no joints. It offers 2 ½ times better insulation and the manpower required is  just 1/10th as compared to brickbat coba. It provides fool-proof waterproofing that is leak-free and guarantees a superior performance in comparison to Brickbat Coba.

What pre-requisites should be followed before waterproofing a structure? How effectively can that be done (roof-top landscape amenities and external façade)?
The reliability of construction depends on the civil engineering techniques adopted, technologies used, and most importantly the materials that go into the construction. To have long lasting structures, the best quality construction materials and performance enhancing additives should be used. Since construction materials include cement, aggregate, concrete, reinforced steel, bricks, tiles and various types of composites, the quality of each material should be assessed in an accepted laboratory, using standard test methods. Using specific additives in the construction material improves the integral waterproofing properties of cement, concrete and plasters after curing. It helps prevent cracks, rusting and leakages. Hence it would also prevent construction decay and keep the structure stronger for a longer period.

The right waterproofing compound should have the built-in capacity to neutralize the excess salt and clay if present in the sand used for construction. As cement is basically water-based, the product that is used for waterproofing work should also be cement and water-based. No waxy material which is freely available these days in the market should be used, whether they are coloured or colourless. They form a coating on the surface and cannot last for more than one season. They start cracking up during summer season leading to more leakage during monsoon. It should not be assumed that cracks alone cause leakage and then go look for crack filling products. Water can seep through wall plaster even if there are no cracks. This is because the wall plasters made out of sub-standard sand & cement virtually behave like blotting papers absorbing water and pushing it right through the walls. Hence, crack filling alone gives only a partial & temporary relief. A product that is cement and water-based, withstands weathering, not only fills cracks but also plugs micro-holes in the cement structure. It is also capable of virtually rejuvenating the defective structure.

Explain about Crystalline waterproofing of concrete.
Crystalline Waterproofing is composed of high quality cement, properly selected & graded inert aggregates, proprietary waterproofing active chemicals & additives. It is used as a chemically active waterproofing treatment for concrete. When mixed with water and applied as a brush coat to concrete, it penetrates deeply into the capillaries of the concrete & protects it against the permeability of water. It can also be dry Shaken or Broadcasted before concreting or on green concrete..

What sets Dr.Fixit apart from its competitors?
The zeal to innovate and provide quality solutions to our customers is embedded in our DNA and this is what makes us unique and drives us. Our vision is to be more customer-centric with the consumer being placed in the highest regard. This means focus not only on products but also services and innovation. At Dr. Fixit we continuously interact with our users, influencers and consumers to know the ‘need’ and create specific solutions offering the best results. The ‘surface’ wise solutioning is one such direction. Also, the help line, SMS connect and Tech Chat are efforts to be close to our consumers & help them in their journey of building a home.
