Water tanks are meant to store water safely without any signs of leakage. But here it’s not just question of leakage. The primary problem is avoiding the growth of fungus.
You’d wonder how fungus in formed? At times, seepage and leakage from overhead and underground tanks spoils the décor. This in turn helps the growth of algae and fungus, which leads to weakening of the structure.
For this reason such areas should be made waterproof as well as safe for potable water
For a new water tank, we recommend using Dr. Fixit Pidifin 2K, an acrylic cementitious waterproof coating over the concrete surface followed by plaster on it. To control dampness and fungus in existing water tanks, we suggest Dr. Fixit Dampguard - a 2 component epoxy waterproof coating. This helps to protect the tank from forming algae and fungus or any other bacterial growth.
Usually, the biggest concern with such water tanks waterproofing products if it will affect the taste of the water. No one wants to mess with drinking water.
Fortunately, these products contain materials that are completely safe to use with drinking water also, as it has been approved by Central Food Testing Research Institute (CFTRI), Mysore for its potabilty and safety.
