What is a Bituminous Membrane?

Bituminous paints are made of bitumen or coal tar which is dissolved in mineral spirit or naphtha. Bitumen is also known as asphalt which is a sticky, black, and highly viscous liquid or semi-solid form of petroleum. Bitumen is commonly used for waterproofing flat and low-sloped roofs. It provides a protective barrier against water penetration, preventing leaks and water damage to the building structure.

Bituminous paint is a type of bituminous coating product that provides weatherproofing and corrosion resistance to the elements. It has good adhesive properties. A bituminous coating is used to build a vapour-proof and protective coat in accordance with its formulation and polymerization grade. The bituminous coating is also known as asphalt coating.

Bituminous paint is strong, waterproof, durable and economical. It resists manufacturing harsh chemicals and UV light. It also protects surfaces from rust.

Advantages of Bituminous Membrane

• Used directly underneath asphalt
• Durable
• Flexible when cold and hot
• Good weldability
• High mechanical resistance
• High puncture resistance
• High performance: with a reinforcement Glass fleece, the membrane has a perfect dimensional
                stability.
• Dimensional stability at high temperatures when pouring the asphalt
• Easy to repair tears or holes in the system
• It comes in rolls, which ease the application and keep costs down
• Manufactured in a factory which means the quality control is good
• It expands and contracts with the movement of the building
• It resists UV light, which reduces cooling costs in the summer and prolongs the life of the roof
• Offers good insulation and energy efficiency (high R-value)
• Requires minimal maintenance
• It can be applied on top of the existing roof, eliminating the need for costly tear-off and disposal
