How it looks after the application is visible in the second image. In addition to roof I also applied 12-15 inch on walls that's also visible in the pictures.
Water tank, first we built 4" outside wall, then we placed 2 layers of the sheet and then 4" of concrete wall inside it.
In this heat we get cool water here while in the other house where there is not insulation on water tank we get hot water. Imagine showering with hot water in summer.
PS. If anyone interested in applying ultra seal here are some tips.
Don't do with material contract and ask them how many kits will they use. One kit is recommended for 12-15 sqm (130-160 sqft). Most contractors put water in it and only use half the product and you end up with a very thin layer of protection.
At the time market price for one kit was Rs. 1800 but I got it direct from factory at Rs. 1600. I bought 18 kits and hired a contractor on labor rate. Contractor was baffled why am I using so much product. He said they use only 6-8 kits on similar area.
Also make sure the surface is clean before application. There should be no sand, mud or visible dust on the surface.
