Sustainable Waterproofing Technology

Water is the main cause of building decay and deterioration. Building materials have considerably shorter life span when subjected to water moisture over a prolonged period of time. The importance of waterproofing is reflected in the consequences of not doing proper waterproofing at the time of construction. Water which penetrates in concrete can have immediate and long-term effects on the building in the form of damage to building contents and even structural failure if the problem is not dealt quickly and successfully.

In such training programs, we also discuss the global standards and pre-requisites for the best application practices.

Although in the market, versatile waterproofing products are available in plenty but in most cases the system fails due to wrong products selection for application. How can such problems be tackled to benefits the users?
My belief is that all companies are committed, in their own ways, to bringing the best solutions to cater to current market requirements. In addition, there are agencies (government and non-government) that are working to establish defined codes and standards for application and product selection. We are also working with such agencies to share our application expertise, so as to benefit the industry.

What is the role of quality standards in waterproofing materials and solution and also tell us what are the systems placed in your company to ensure quality standards?
As in any application, performance is a given expectation in any industry, and at Dow Corning providing quality solutions is one of our core values. Like I said earlier, we have established a laboratory facility to test substrates. Accordingly, we recommend the right product based on the substrate. At Dow Corning, we believe in offering the best-suited solution for the market.
