Crack filling ranging between 5 – 50 mm wide in concrete / flexible roads, and used for surface correction in concrete road / pavement.


  • Tough, Flexible and Durable.
  • Rapid Cure time.
  • Excellent resistance to chemical, saltwater, oil, acids, alkalies, crude oil, fuels and minerals.
  • Compatible with both coal tar and asphalt emulsion based sealers
  • Compatible with both concrete and bituminous pavement.
  • Excellent to repair surface defects of the road.

ShaliSeal RS TC

To protect Asphalt Wearing surface from water, fuel and other volatile substances  ingression . STP’s new development of ShaliSeal RS TC – Coal Tar Based Slurry Seal has solved the problem to a great extent. Coal tar, being highly water & fuel resistance , prevent the Asphalt Wearing surface and reduce the periodical maintenance cost substantially. The same is also recommended to use on Granular Sub-base as Prime Coat to protect the sub-base as well as bonding with the bituminous macadam. It is already been recommended by NHAI, IRC other Road Consultant. MNCs like HONDA and many others had also opted for the same for their internal Asphalt Pavement. STP recommend the use of ShaliSeal RS TC over existing Asphalt Pavement every year just before monsoon to enjoy a Pot-Holes Free wearing surface years after years.
