Bituminous Waterproofing :
A Bituminous waterproofing coating is a type of coating used for waterproofing.This is flexible protective coat in accordance with its formulation and polymerization grade. Its flexibility and protection against water can be influenced by the polymer grade. As well as this waterproofing material is reinforcement of fiber. This method is basically coating of a flexible asphalt layer.it is well-known waterproofing material, or in general practice, we call it coal-tar. A bituminous coating is also called an asphalt coating. The most common applications of bituminous waterproofing material coating include areas that are under screed wet. It is a super excellent protective chemical coating and waterproofing agent.it works excellent especially on surfaces such as concrete foundations.
this waterproofing coating is made of bituminous-based materials and it is not suitable for the situation to expose to sunlight. It often becomes very brittle and fragile when long exposure to the sunlight unless it is modified with a more flexible material such as Polyurethane or acrylic based polymers.this kind of waterproofing material is surely cost effective .
The flexibility of the finished products always depends on the solid content of the polymer added to the bitumen.
