Home Sealants Bitumen Sealants Bitumastic


Bitumastic is a single component, solvent based bitumen rubber mastic joint sealant. The sealant on curing forms a tough and flexible seal. It has excellent adhesion to concrete, brickwork, asphalt and most construction material substrates. The mastic sealant is modified with non asbestos fibres to make the sealant thixotropic and slump free when applied on vertical areas.

Good expansion and contraction properties.
Good tensile strength & elongation.
Pliable and flexible.
Stability at high ambient temperatures.
Excellent adhesion, strong durable bond.
Single component

Fields of Application 

  • Bitumastic is ideally suited for sealing and filling gaps and joints on roofs, pointing horizontal chases for waterproofing membranes and felts. Sealing around roof/wet service pipes. Pointing between brickwork and roof flashings. Sealing cracks in asphalt and concrete pavements. Filling horizontal joints in concrete and asphalt where movements are not expected.
