  •  Why do I need water tanks waterproofing for a new home?

    Water tanks are meant to safely store water without any leakages. But here it’s not just the question of leakages. The primary problem is avoiding the growth of fungus. You’d wonder how the fungus is formed? At times, seepage and leakage from overhead and underground tanks spoil 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 this, you have to employ the right water tank waterproofing method using the right products—Dr Fixit Pidicrete URP & Dr Fixit Fastflex. Before using these water tank waterproofing products, make sure you keep the following things in mind:

    1. Surface to be treated should be clean and free from dirt, oil and other loose material
    2. Concrete or masonry surfaces should be fully cured before application
    3. All surface cracks, undulations and voids must be repaired appropriately before application
    4. Correctly grout all construction joints using polymer modified mortar using Dr Fixit Pidicrete URP
    5. Surface to be treated with Dr Fixit Fastflex must be in a saturated surface dry condition before application​
  •  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. For other water tank waterproofing, we suggest Dr Fixit Dampguard. The two-component epoxy waterproof coating can help protect the tank from forming algae and fungus or any additional bacterial growth. 

    Usually, the biggest concern with such water tanks waterproofing products is if they will affect the taste of the water as no one wants to mess with drinking water. Worry not. These products contain constituents that are entirely safe to use with drinking water. The products have been approved by CFTRI, Mysore for its potability and safety. Hence, Dr Fixit Pidifin 2K surely does work as effective water tanks waterproofing solution for new homes

Water Tanks Waterproofing

Water tanks are made up of concrete, which is flexible and prone to crack over time. Water tanks waterproofing servicesare considered as one of the most difficult types of waterproofing services. Water tanks need a cementitious coating to arrest seepage and products which are food-grade. The water tanks waterproofing solutions are dependent on the position of water tank: overhead or below ground. For waterproofing below ground water tanks, two things are required to keep in mind—no leakage from the tank and no ingress of water from the soil. The waterproofing layer must be firmly bonded to the walls of the water tank to withstand the negative pressures when the water tank is emptied or water table of the soil is raised. The overhead water tanks must be effectively waterproofed so as to not cause any leaks. They must be sufficiently elastic to withstand the expansion and contraction of water tank walls and floors with changing temperatures. Repairing an existing water tank is time-consuming and causes inconvenience. Hence, employing the right water tanks waterproofing solutions for new homes is crucial.

Why Dr Fixit Water Tanks Waterproofing Solution

The water tanks waterproofing for below ground tanks is said to be successful when the walls and floor of the water tank are waterproofed to withstand the hydrostatic water pressures. The internal tank surface must be coated to form a continuous, uniform waterproof membrane. The membrane must have high strength and strong bonding to the substrate. Dr Fixit takes care of all the above-mentioned problems while waterproofing water tanks. For overhead water tanks, the walls and floor must be coated with a waterproof membrane that is durable, long-lasting, and firmly bonded. The layer must be highly elastic to take care of the expansion and contraction of the concrete due to change in external temperatures. Dr Fixit offers the best water tanks waterproofing solutions in India.
