Custom Bunded Tanks

When liquid containment is an absolute priority, a Promax Custom Bunded Tank is what you need.

Because of its “tank in a tank” design, a bunded tank ensures liquids stay within the confines of the tank, even if a leak occurs. It’s simple: an inner tank holds the liquid, and if there is a leak, it is safely captured within the outer tank. Any liquids with potential contaminants must be contained for compliance and environmental reasons, and a bunded tank will satisfy council requirements when storing such liquids.  

  • A wide range of sizes are available up to 25,000 litres 
  • Multiple liquid weights up to 2.0 SG 
  • Special fittings, inlets and outlets 
  • Removeable roof options 

Protect your industrial workplace, surrounding environment, and waterways by investing in a bunded tank built to your specifications.

Contact the Promax industrial team to discuss your requirements and how to stay compliant.

Seismic restraints add another layer of safety by acting as a set of anchors for large industrial storage tanks. A series of restraints around the tank's base are bolted into a concrete pad to hold the tank in place and prevent movement during an earthquake or other events, including cyclones and floods. A poly tank set solid and immovable at the base, and with flexibility and durability throughout the rest of the structure, appeals as the safest and most robust option for liquid storage.  Click here to learn more about Seismic restraints.
