Al Yaqoub Tower is a tall building in Dubai, United Arab Emirates. The tower reached its peak in 2010 and was completed in 2013.
Problem: To avoid seepage from wet areas and make structures durable.
Application: Waterproofing by crystallization.

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,...
