STP Ltd is the market leader in the field of Construction Chemicals and allied products in India and is OEM to numerous National & International companies. STP Ltd has received numerous awards and is recognized as the master in the Field of Waterproofing and innovative technologies. Structures are exposed to the aggressive environment like carbonation, Alkali silica reaction, Moisture etc., resulting in corrosion of reinforcement and deteriorating the quality of concrete. Today the experts from STP Ltd have advanced on durability, repair, and protection of structures and have developed state-of-the-art materials and techniques. ShaliPlast LW++is an Integral Waterproofing-cum- Corrosion Inhibitor for Reinforced Cement Concrete (RCC) it’s a revolutionary liquid waterproofing compound. Which protects concrete internally from water ingress as well as saves the re-bars of reinforced concrete and mortar against chloride induced corrosion. The unique bipolar compound migrates through concrete during curing process and puts a passive layer over rebars to stop chloride corrosion.
In India the condition of most of the roads is pathetic, especially during the monsoon. 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 Ltd has developed specially ShaliSeal RSTC, which is a coal Tar based sealer and almost unaffected by water. This product has been applied on various Roads of NHAI, PWD and other institutions and has given incredible results.
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 deteriorated by water. Time has come for us to use a water-resistant sealer on roads; the answer is ShaliSeal RSTC from STP Ltd, this is an incredible product set to revolutionize the Indian Roads.
Advantages of Waterproofing of Roads by ShaliSeal RSTC
- Top coat Road Slurry for Enhancing Road Life by preventing Water ingress
- This is a refined coal tar-based emulsion, designed to protect Asphalt pavement.
- Resists Ultra Violet Radiation
- Resists Fuel impregnation
- Reduces aging of Asphalt
- Hence reduces vehicle maintenance

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, which 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 a number of bridges in India. The Process consists of application of Shalitex Primer followed by torching of Super ThermoLay APP membrane 4mm thick followed by overlay of bituminous wearing course and finally application of ShaliSeal RSTC.
ShaliPatch EC: Repair of cracks in Rigid & Flexible pavement to prevent ingress of water, by cold applied polymerized elastomeric Concrete crack filler. Crack filling ranging between 5 - 50 mm wide in concrete / flexible roads and used for surface correction in concrete road / pavement.
Coloured Roads: Bitumen is black due to presence of Asphaltene. Bitumen fails to provide coloured surfaces, which is required to serve specific purpose. STP Ltd has developed ShaliSeal CSS A forCycle tracks, Bus lanes, Parking bays, Highway road signalling, Sports venues, Walkways / pathways. Aesthetic application, landscaping, tunnel road. The advantages of ShaliSeal CSS-A are:
- It is Solvent / VOC free, good friction / skid resistance, tough and durable, excellent UV / ageing resistance. Rapid cure can open traffic fast, cold pour and ready to use. It does not require any heating.
- Excellent resistance to chemical / salt water / crude oil, acids / alkalis.
- Compatible with both concrete and bituminous pavement
STP Limited, an Indian Company with over 80 years backing, is the most trusted name in the field of Coal tar/Bitumen/ Construction Chemicals, for its Quality & Services and is one of the most preferred brand in the Indian Market.
