Today one cannot imagine civil construction without the use of some constriction chemicals
For the longest time, waterproofing of underground structures was achieved through BOX TYPE waterproofing. Membrane-based waterproofing using membranes of various types such as PVC membranes, APP/SBS membranes, EPDM membranes or TPO membranes were the preferred choices. All these technically created just built a method of creating a physical barrier outside the concrete surface. These methods are time consuming, expensive and less reliable.

What is your view on the construction chemicals market presently?
For the longest time, waterproofing of underground structures was achieved through BOX TYPE waterproofing. Membrane-based waterproofing using membranes of various types such as PVC membranes, APP/SBS membranes, EPDM membranes or TPO membranes were the preferred choices. All these technically created just built a method of creating a physical barrier outside the concrete surface. These methods are time consuming, expensive and less reliable.
With new innovation and advent of technology, now we work with creating Integral Crystalline waterproofing admixtures. Using such technology ensures water tight structures where the concrete that is water tight by itself. In this method, Integral Waterproofing admixture is added to the concrete at the batching plant resulting in up to 90% reduction in co-efficient of permeability of the concrete, thereby producing a water tight concrete.
The construction chemicals market has evolved over time and now we observe that there are several construction-related activities, where construction chemicals have replaced traditional methods of construction, leading to increased demand. In the present day construction, one cannot imagine civil construction without the use of some constriction chemicals.
What are the key products and solutions offered by the company in construction chemicals?
Our company specialises in the field of Crystalline Durability Admixtures and the entire range of crystalline waterproofing and concrete repair products.
Penetron Admix, a third-generation crystalline concrete-enhancing admixture, is the most advanced formula to effectively waterproof concrete structures. It eliminates problems related with first and second generation admixtures such as loss of compressive strength and unusually long delays of the setting time.
Penetron Admix can be applied to any commonly-used concrete mix in today's construction industry. It doesn't have any known incompatibilities with other workability enhancing admixtures such as retarders or super-plasticizers and there are no limitations in regards to the w/c ratio of the concrete to be treated. With dosage rates as low as 0.8% (by weight of cement) it is not only one of the most cost-efficient and economic waterproofing choices, but an effective formula that has been proven in many international laboratory tests and on countless projects worldwide.
Penetron Admix is a non-toxic product and is approved for use in projects involving potable water (NSF 61 approval, European Environmental License). Penetron Admix does not contain any volatile organic compounds (VOC) and is used in green projects acquiring LEED certification points.
When applied to concrete Penetron Admix assists in the hydration process acting as a catalyst to un-hydrated cement particles already existing in the concrete. This already takes place in the early stages of the cement-reaction resulting in the development of internal strength build up compensating to some extent the formation of shrinkage cracks as well as the increase in compressive strength. At the same time, a longer workability of the fresh concrete is provided.
How do you view the demand trend of construction chemicals in future?
With the increase in demand for urban housing and the past pace of infrastructure development, the construction chemical industry is likely to see a growth of 25% YoY for next decade.
