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 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...

MECHANISM OF WATERPROOFING
Mechanism of Waterproofing by Proper Cement Hydration
One of the products of hydration of cement is cementgel or Tobermorite, which is formed upto water cement ratio 0.65 to 0.7. At lower w/c ratio, it is formed more and more and vice versa. This hydration product has absolutely least co-efficient of permeability, i.e., 7x10-14 cm/sec and by itself blocks the pores and capillary in the concrete. This can result into good waterproof concrete of 10-10 to 10-12 cm/sec. However,...
Various permutations and combinations in specifications can avoid such problems, for example, the following alternatives can be considered:
1.Give a water impermeable coating on the finished surface of IPS – Though this method can prove effective on a short-term basis, may create problems subsequently. It is observed that the coatings based on pure solvent-based polymers, though effective do not function for a larger duration due to its requirement for a thoroughly clean and dry surface. From...
