How to Repair Concrete Water Tanks A concrete water tank can develop cracks over time. Your tank’s cracks may have been created from soil shifting beneath the tank, or perhaps from the freeze-thaw cycle expanding and contracting the concrete during extreme weather conditions. Regardless of the reason, these cracks can cause your tank to leak. Not only will a leak drain away the water contained in the tank, it may also allow bacteria to build in the crack, making the water unsafe for use. When a crack develops, you can quickly repair it using a patch created of hydraulic cement, or with a combination of cement patch and liner. Repair tanks holding drinking water by first measuring the tank, noting both the circumference of the tank as well as the tank depth. Order a tank liner from a liner manufacturer to the dimensions needed. Make sure you order a liner rated as food-grade level rubber. Drain the tank completely and clean out the crack, removing any dirt or debris with a wire brush.

Remove any loose concrete that may be located around the crack with the chisel. Take care not to chisel directly into the crack though, as this could spread the crack. Brush a layer of concrete bonding agent into and surrounding the crack, making sure to cover the entire inner surface of the crack. Wait about five minutes for the agent to dry to a point where it’s no longer wet but remains tacky to the touch. Mix one part hydraulic cement with three parts water in a bucket using the electric drill with mixer paddle attached.

Scrape over the surface of the cement with the tilted edge of the trowel to make it even with the surrounding concrete. Remove any excess cement and allow the patch to dry for an hour. This is all that is necessary for tanks not used for holding water for consumption. Coat the entire interior of the concrete water tank with epoxy to serve as an adhesive for the liner. Roll the resin onto the concrete using a paint roller. Install the liner in the tank’s interior starting at the center of the tank. Place the center of the liner in the tank’s center, pressing firmly on the liner so it adheres to the concrete. Unfold the liner, spreading it across the bottom of the tank and then extending it up the sides of the vessel. Drill holes into the concrete where the steel reinforced holes on the liner’s edges are located using the hammer drill. Inject epoxy into the concrete holes to help hold the anchors in place and then pass the anchors through the steel reinforced liner holes into the concrete holes to hold the liner in place.

Allow the epoxy to dry completely for the length of time specified by the manufacturer before refilling the tank.

Repair leaks and prevent costly damage with the help of QUIKRETE Hydraulic Water-Stop. When working with cement-based products, always wear eye protection and waterproof gloves. Using a masonry chisel, enlarge the crack to a minimum ¾-inch width and then remove all loose material.

Squarely cut or undercut the edges of the crack. It is important not to create “v” shaped edges as the Hydraulic Water-Stop expands as it hardens. Mix Hydraulic Water-Stop by adding about 4 to 4 1/2 parts Water-Stop cement to 1 part clean water. Use a margin trowel to thoroughly mix the material to a heavy putty consistency, making sure that the mix is uniform and lump free. If the mix is too wet, add additional Water-Stop cement and mix thoroughly; if the mix is too dry, add small amounts of water sparingly. NOTE: Hydraulic Water-Stop sets extremely fast, so do not mix any more material than can be used in 2-3 minutes. Once a putty consistency is achieved, take a handful of Water-Stop in your gloved hand and begin to work the material into a ball. Press the Water-Stop cement into the crack using heavy pressure and hold in place for several seconds. After the material has become “thumbprint” hard, use a margin trowel to trim the patch to match the contour of the surrounding surface.
