Understanding Bituminous Waterproofing Solutions
A bituminous coating is made of bitumen based materials and is not suitable for direct exposure to sunlight. It becomes very brittle and fragile when exposed to the sunlight extensively unless it is modified with polymers such as polyurethane or acrylics. The flexibility of the finished coating always depends on the amount and type of polymer added to the bitumen.
Bituminous waterproofing is done to protect residential or commercial buildings in a budget friendly manner. Bitumen or asphalt is made up of highly viscous organic liquids which are also waterproof. These systems are used in roof constructions in the form of roll products.
