Concrete Water Tank Repairs

Concrete water tanks are prone to cracking, and when the cracks begin they can leak, causing water loss and a significant cost burden. The freeze-thaw cycle of extreme weather conditions can also compromise the tank’s structure.

In addition, concrete is porous and susceptible to contamination. As these issues accumulate, a tank may require costly repair or even removal and replacement. Stainless steel tanks are much less prone to these issues and offer the peace of mind that the tank’s contents are safe and sanitary.

The key to keeping a concrete tank in service is frequent inspections, so that issues can be identified and addressed quickly and effectively. In the case of a leak, it is very important to identify the location of the leak and to drain and clean the tank regularly.

Once the source of a leak has been determined, it is necessary to determine the extent of the damage. Often, minor repairs can be made while the tank is still in use. However, major repairs will usually require the tank to be drained and temporarily taken out of service for safety and effectiveness.

If structural cracks are present, various repair solutions include epoxy liquid injection, surface-applied carbon fiber composites, pinning or stitching and hydro-active grout injection for waterproofing fissures. Additionally, coatings and tank liners such as FRP (fiber-reinforced plastic) can be applied to the walls of a tank. These products provide corrosion resistance and thermal insulating properties. concrete water tank repairs
