Many concrete water tanks are built to store drinking water or waste products. Because they are exposed to the elements, these structures must be inspected regularly and repaired when necessary. Having a qualified engineer perform the inspections is key to keeping these in-service structures structurally sound and leak free. Often, the problems with these tanks are easy to fix and do not require replacement.
One of the most common issues is cracks, and this can be a sign of serious trouble with the tank. These cracks can be caused by soil shifting under a tank, or the freeze-thaw cycle of extreme weather conditions.
Regardless of the cause, it is important to repair these cracks as quickly as possible. There are a number of different products on the market, but each is best suited for specific situations. For example, if the tank has a continuous leak, it is best to use a hydrophilic product that will expand when it comes into contact with water.
If the crack is dry, it will need to be filled with a cement-based product that will harden. This will prevent the crack from widening and allowing water to escape.
When performing concrete tank repairs, it is always wise to work with a qualified professional who will know the proper procedures for preparing the surface and applying the product. It is also important to follow all local and OSHA safety requirements for working in confined spaces. concrete tank repairs
