Hi,

Pl suggest water proofing compound for water tank intended to use for my house

1) For mixing in concrete & In which ratio.

2) For Inside Plastering & In which ratio.

Thanks in advance.

As you will be aware, there are plenty of construction waterproofing chemicals out there. You can check BASF, Fosroc, Sika etc etc. If I'm informed correctly Sika is quite common in india. Make sure you check the datasheet/supplier if the chemical is appropriate for potable water storage tanks (if that is the intended use of the tank).

there is another product called penetron seems to be very good product. this one you need to add to the concrete mix. you can Google it go to their website for more information. I think you should able to get this product as it popular world wide.
