Waterproofing Practices – An Introduction
“No material is itself durable or non-durable, it is the interaction of the material with its in-service environment that determines its durability” – says a well-known concrete technologist Larry Masters. Thus, with reference to concrete, durability will depend on the nature of the concrete (and that means impermeability) and the aggressiveness of the in-service environment. The three important steps that ensure adequate durability of concrete in-service are:

Modern-day structures are indeed more complicated than the earlier ones, which were constructed, say 20-25 years ago. Earlier, a mere conventional waterproofing treatment of terrace, toilet, bath, sinks, and an old basement needed the waterproofing job.
However, these days the structures are high-rise, they have a large podium, car-parking lots, basements, terrace garden at each duplex flat level, corporate office gardens, flowerbeds, swimming pools at various levels, narrow ducts (chowks) for plumbing lines, and electrical lines besides conventional problems of regular large terraces.

Mechanism of Waterproofing by Proper Cement Hydration
One of the products of hydration of cement is cementgel or Tobermorite, which is formed up to water-cement ratio 0.65 to 0.7. At a lower w/c ratio, it is formed more and more and vice versa. This hydration product has absolutely the least co-efficient of permeability, i.e., 7×10-14 cm/sec and by itself blocks the pores and capillary in the concrete.
This can result in good waterproof concrete of 10-10 to 10-12 cm/sec. However, actually, in practice at an average job, we end up getting the permeability anywhere between 10-6 to 10-8 cm/s

In the earlier article, we discussed how Rusticide helps in the removal of rust from steel. Now once the corrosion (rust) has been treated using Rusticide, it is necessary to prevent it from rusting thereafter to ensure that the structure can meet its designed service life.

Waterproofing is the treatment or protection of structures and objects that make them waterproofed. It acts as a barrier for terraces, walls, roofs, and other structures which keeps them away from water, soil moisture, etc. Waterproofing is installed by using modern technology which should be effective during monsoon, climatic changes & weather conditions.
