ShaliSeal RSTC applied on elevated roads
Structures are exposed to the aggressive environment like carbonation, Alkali-silica reaction, Moisture, etc., resulting in corrosion of reinforcement and detoriating the quality of concrete. Today, the experts from STP have advanced on durability, repair, and protection of structures and have developed state-of-the-art materials and techniques.
In India, the condition of most of the roads is pathet, specially during monsoons. The reason is simple, water entering the roads is the main cause of damage. The life of the roads can be increased by providing proper side drains and water-resistant top layer. Over the years, STP has developed unique ShaliSeal RSTC, which is a coal tar-based sealer and almost unaffected by water. This product has been applied on various roads constructed under NHAI, PWD and other institutions and has given incredible results.
Bitumen has been used as a paving material since 18th Century. It detoriates under ultraviolet rays, gets dissolved by Petrochemicals, attacked by chemicals, deicing salts, etc. It also gets detoriated by water.
Currently, bitumen-based fog sealer are used in India. The need to use water-resistant sealers on roads have emerged now. And the answer to this need is STP's ShaliSeal RSTC which is an incredible product to revolutionise the Indian roads.
Features of ShaliSeal RSTC:
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 enemies – Water. STP has been associated with Bridge deck waterproofing using SuperThermoLay APP membrane. These membranes prevent the ingress of water into the bridge's concrete, thus, preventing harmful ingredients from damaging the concrete. This system has been applied successfully on number of bridges in India. The process consist of application of Shalitex Primer followed by tourching of SuperThermoLay APP membrane-4mm thick, overlay of bituminous wearing course, and finally application of ShaliSeal RSTC.
Colored Slurry Seal 'ShaliSeal CSS': Bitumen is black due to presence of Asphaltene. Bitumen fails to provide colored surfaces which is required to serve specific purpose. STP has developed easy to apply Coloured Slurry Seal with following highlights:
