Water tanks waterproofing

Concrete is less flexible and cracks over time. Repairing an existing water tank is a time consuming process and cause inconvenience to the residents.

Recommended Solution

Use Dr. Fixit Pidifin 2k, a two component waterproof coating for overhead water tanks. The benefits are:

  • A heavy duty waterproof coating
  • Safe to be used for storing drinking water
  • Life expectancy for 5 years  


Conventional Method

A cement slurry is supposedly used to waterproof the tank which temporarily arrests the leakage from cracks & joints.

What is the need for Water Tanks waterproofing?

Seepage and leakage from overhead and underground tanks spoils the décor, helps growth of algae and fungus and leads to weakening of the structure. Such areas hence need to be waterproofed but also at the same time safe for potable water.

Q. Can we use a waterproofing product inside the water tank? Will it hamper the taste and the potability of water?

To waterproof the water tank from inside, we recommend using Dr. Fixit Pidifin 2K, an acrylic cementitious waterproof coating OR Dr. Fixit Dampguard, a 2component epoxy waterproof coating. They are completely safe to use with drinking water also, as it has been approved by CFTRI, Mysore for its potabilty.
