Liner to suit a tank up to Diameter4500x2240mm deep Volume~35.6KL based on internal dimensions of the tank. Refer to tank supplier for actual and maximum capacities of your tank.

Repair old leaking concrete tanks with 1mm thick BUTYL rubber. Butyl rubber is the ideal material for storing clean, clear, drinking water without the unpleasant taste you will get from a storage methods which use plastics such as PVC or polyethylene. Also, unlike most plastics, butyl will not break down under direct sunlight. These bladders can endure temperatures up to 80 degrees Celcius without causing permanent damage to the material.

Butyl rubber is tough and will stretch up to 300% and still return to its original relaxed state. However, to get the best longevity out of the liner, all care should be taken to ensure the liner rests against a smooth even surface. The inside of the tank should be checked for holes - all holes should be covered or rendered prior to fitting the liner. Remove all sharp objects that could potentially puncture the liner. Refer to Southland's installation instructions for more information. We also recommend you purchase some liner underlay material (available in our store).
