In parts of the world with insufficient water and the threat of drought, water storage is a necessity. Tanks that hold hundreds of gallons of water may be made from concrete. Sealing these tanks prolongs their lives and reduces the danger of leakage. An underground concrete cistern must be sealed earlier than it can be backfilled and buried. Smaller, above-floor concrete water storage programs could be sealed at any time.
Things You’ll Need
Concrete seam tape
Water sealing primer
Concrete water sealant
Clean all mud, dirt, mud, grime, moss and unfastened material off of the exterior surface of the concrete water tank with a wire brush.
Apply concrete seam tape to any cracks which might be seen on the surface of the concrete, in addition to to any joints that you see within the construction of the water tank, for added safety.
Apply water sealer primer to the floor of the tank. Different concrete sealing merchandise are available, so be sure that yours are compatible. Mixing a primer with a sealing coat from a unique producer is not beneficial since they might react in unpredictable methods. Depending on the product that you utilize, it may be either brushed or sprayed onto the floor of the concrete. Allow the primer to dry for 24 hours.
Apply two coats of concrete water sealant to the floor of the water tank using a spray gun. Anticipate to use about 2 gallons of material for each one hundred sq. feet. This product needs to be utilized thickly, as much as about 1/8 inch, to ensure imperviousness to water and leakage.
