Concrete tanks are a robust class of infrastructure but they are prone to cracking and leaking over time. This is particularly true of buried concrete septic tanks and wastewater tanks. When this happens it is a huge problem because the cracks can allow sewage or water to leak out of the tank and into the surrounding soil, it can also make the water in the tank unusable. Repairing a cracked water tank isn’t cheap.
One of the best ways to prevent these leaks is with a concrete tank liner. These heavy-duty liners are designed to fit the shape of any tank and they help keep the stored water safe by preventing it from leaking into cracks in the concrete itself. In addition to this, the liners also provide a barrier against erosion which is a common problem with buried concrete tanks over time.
To repair a leaking concrete water tank, Taskers first drain the tank below the point of the crack, clean and dry the surface then drill a hole on either side of the crack and heat the surface of the concrete using a torch or welding iron. This helps to melt the crack edges so they can be fused together. Then they apply a thin layer of Thoroseal to the cracks which fills them and seals them. This is a Portland cement-based coating that resists hydrostatic pressure, is non-toxic in potable water tanks and won’t crack or peel off like concrete. concrete water tank repairs near me
