Polyurethane waterproofing products
This relatively new product has quickly become a fast-growing product among waterproofing contractors in South Africa. It is therefore vital that more contractors use and adapt to this product in their waterproofing processes and understand the product better.
What is Polyurethane?
Initially invented as an adhesion, Polyurethane has been around for over 30 years. However, it has only been in South Africa for a small period. Polyurethane is a non-toxic liquid-based system that will attach to about any cooling material such as concrete, bricks, wood and glass. It is entirely seamless and can easily be applied by either a brush or a roller. The product is non-toxic and entirely safe to be used in water tanks and the like. It comes in different colours, depending on the volume required by the client.
How does it react to different temperatures?
A lot of the Polyurethane range products and especially the range used by Bitumproof can deal with temperatures going as low as -30 degrees and as high as 90 degrees.
Most of these products come in a one part application, but it can also come in a two-part application. Polyurethane products can be applied by brush, roller or spray, depending on the type of product. After some training and knowledge of the product, the application is quite easy. Due to strict quality assurance, the products are not available in stores as DWASA requires proper training before using and applying these products. Training is necessary to know which product to use for which application. Laymen must therefore be properly trained to fully understand which products go with which applications, and how the build-up process works.
One would usually start with a primer, then put on two coats of waterproofing material. If it is exposed to UV, there would also have to be a protective top coat.
Bitumproof SA polyurethane is UV resistant and therefore does not require any maintenance
Waterproofing contractors should take note of this high-quality, versatile and effective system of waterproofing which is now available in South Africa.
Bitumproof is proud to use these products in their waterproofing processes.
