Concrete Water Tank Repairs

Over time concrete tanks develop cracks and leaks. These leaks are caused by expansion and contraction, freeze-thaw cycles, pinning/stitching of reinforcement, and corrosion. Eventually, these tanks will need to be replaced. Thousands of municipalities have waste, potable and irrigation water tanks that are at the end of their lifespans.

Some people will attempt a DIY patch repair by buying a liquid membrane product and trying to pour it into the tank. This is a dangerous practice and can lead to contaminated water, blocked plumbing and a huge clean up job. It’s best to consult a professional to ensure the concrete tank is safe and dry before beginning a water tank injection repair.

The Allnex chemical company in Connecticut has a circular concrete water tank that was experiencing some signs of deterioration. It was leaking and they were considering replacing it.

It is possible to do concrete water tank repairs while the tank is in use, but it depends on the scope of the work and the specific conditions. In most cases, it is required to drain the tank completely before beginning any water tank injection repairs. This allows for a safer and more thorough repair process.

Water tank injection repair is a specialised process of applying a cement-based material into the cracks, seeps and holes that cause water loss. Once injected the product fills the crack and seals it. This will prevent further water damage, preventing the steel skeleton of the tank from being exposed. concrete water tank repairs
