BITUMINOUS COATING
Bitumen Mastic
Bitumen mastic, also known as mastic asphalt, is a high-performance building material made from a mixture of bitumen, mineral fillers, and fine aggregates. Mastic Asphalt is a dense, highly durable, and impermeable material with excellent binding properties. This Mastic Asphalt is cold-applied bitumen, with no requirement to heat it before applying it in a molten state to create a seamless, waterproof surface. Its versatile properties make bitumen mastic a popular choice for both construction and maintenance projects worldwide.
Cutback RC 250
Rapid Curing 250 RC250 a combination of penetration grade asphalt cement and a diluent or cutter highly rapid in its volatility making it easier to apply.
Cutback MC 800
Rapid Curing 800 MC800 a combination of penetration grade asphalt cement and a diluent or cutter highly rapid in its volatility making it easier to apply.
PROPERTIES
- Bitumen Mastic is ideal for the durability of structures as it has high resistance to wear and tear and heavy traffic loads. Also, there is no requirement for frequent repairs, which extends the lifespan with minimal maintenance.
- Mastic Asphalt has excellent water and moisture resistance, making it ideal for waterproofing applications.
- Bitumen Mastic is flexible as it adapts to structural movements without cracking, even under varying temperatures.
- Mastic Asphalt has high thermal resistance and adhesion, allowing it to withstand high temperatures and strong bonding to various substrates like concrete, wood, and steel.
- Bitumen Mastic retains its waterproofing properties as it has high chemical resistance such as acids, alkalis, and most industrial chemicals.

USES
- Waterproofing: Bitumen Mastic is ideal for waterproofing applications as it is used in roofs, basements, bridge decks and tunnels. It protects flat and sloped roofs from water ingress, ensures moisture resistance in underground structures, and prevents water penetration in heavy infrastructure.
- Road Construction: Bitumen Mastic finds its usage in road construction and maintenance as it is used as a joint filler, crack sealant, or surface dressing for roads.
- Industrial Flooring: Mastic Bitumen is a perfect choice for industrial flooring as it creates durable, chemical-resistant surfaces for warehouses, factories, and workshops.
- Marine Applications: Bitumen Mastic is employed in marine applications, as it is used in docks, piers, and ship decks to resist water and salt exposure.
- Tank and Pipeline Coating: Mastic Asphalt plays a major role as a coating material. Applied on pipes and tanks to work against adverse weather conditions and protect from corrosion and leaks.
- Expansion Joints and Cracks: Mastic Bitumen serves as a sealant to fill and protect expansion joints and cracks in concrete structures.
