![]() Fixit Coal Tar Epoxy which is an effective solution when it comes to protecting external walls from soil contamination and groundwater. To get rid of this problem, coal tar coating must be applied to the external walls. Poor protective layer on the external walls It is a highly elastic acrylic modified cementitious coating that provides a protective layer of 1mm thickness and works efficiently under varying water pressure. Fixit Pidifin 2K is an ideal choice for dealing with this kind of problem. Inefficient protective layer on the internal wallsĪ polymer modified cement coating that is approved for food-grade coating must be applied on the internal walls, be it underground or overhead concrete water tanks. It is highly effective in minimising honeycombing and pores which help in reducing the problem of water seepage. Solutions for bad practicesĪ waterproofing compound must be mixed during concrete production to reduce water permeability. Poorly sealed openings in the walls of the concrete water tanks are another major reason for probable leakages. Also, the treatment is not effective when it comes to sustaining groundwater pressure. Construction supervisors often leave external walls without any treatment or they use cement polymer slurry which cannot provide the required protection against ground soil and water contamination. Consequently, these contaminate the water and may create health-related problems after consumption.Īnother ignored aspect of water tanks (underground and overhead) are their external walls. The internal walls of concrete tanks are usually finished with tiles which over time are likely to form algae and fungus. As a result, the treatment has no effect and thus fail to perform under constant water onslaught. Taking about the current practice, what they do is they simply apply the coat of neat cement slurry mixed with acrylic polymer or latex which is neither water-resistant nor elastomeric. Since the tank will be storing a good volume of water, it needs special treatment. Many a time, homeowners or even construction supervisors do not give the water tank its due attention. Masons do not add any chemical to the cement which later on, due to constant water pressure, produce excess pores in the whole structure of the tank. Poor workmanship and material are a big concern that gives birth to the problem of leakage. Having said that, let us check out some ongoing practices that lead to the problem of leaking water tanks. Note: One of the logical ways to keep the problem of water leakage at bay is to make sure that the concrete water tank is precisely constructed so that it works efficiently when it comes to enduring varying hydrostatic water pressure. Practices that lead to the problem of leakage Leakage problems are likely to occur in concrete water tanks due to variable water pressure effects on their walls which cause structural movement, resulting in cracks. In most cases, after a few years of construction, the problem of water leakage is likely to occur due to the poor treatments of joints and excess porosity which fail to endure water pressure. Doing so can help prevent water contamination and seepage. Note: Being a critical structure of any building, concrete water tanks must be given special attention during the construction phase itself. ![]()
