Covac Leaking GRP Water Tank

In GRP water tanks a common problem that you may face is the deterioration of the mastic, which can lead to the leaking of water. This can cause you to lose a significant amount of water and damage the functioning of your tank. Osmotic blistering along with air-filled cavities and fine cracks can also cause a breakdown of your GRP substrate.

This will consequently allow bacteria and micro aquatic organisms to harbour and promote their growth. Corrosion can become a major problem for water tanks which have not been lined properly. Corroded surfaces will provide the nutrients for harmful bacteria like legionella. So, it is crucial that if any of these problems arise in your GRP water tank that you have your structure repaired and relined.

This will ensure that your water retaining structure will be protected to prevent future problems and provide a long term solution.
