Bitumen has been used as a Paving Material since 18th Century. It deteriorates under sun’s ultraviolet rays, gets dissolved by Petrochemicals, attacked by chemicals, de-icing salts etc. Presently bitumen-based fog sealers are used in India. We all know bitumen gets weakened by water. We need to use a water-resistant sealer in roads; the answer is ShaliSeal RSTC from STP Ltd, this is an incredible product set to revolutionize the Indian Roads.
ShaliSeal RSTC:
  • Top coat road slurry for enhancing road life by preventing water ingress

Bridge Deck Waterproofing: Bridges are one of the major life lines in connecting people. They need to be protected from one of their major silent enemy that is water. STP Ltd has been associated with Bridge deck waterproofing using SuperThermoLay APP membrane. These membranes prevent the ingress of water into the Bridge concrete, thus preventing harmful ingredients from damaging the concrete. This system has been done successfully on number of bridges in India. The Process consist of application of Shalitex Primer followed by torching of SuperThermoLay APP membrane 3 or 4mm thick followed by overlay of bituminous wearing course, followed by Application of ShaliSeal RSTC.
