Collapsible Bund Stands are Tough and Strong 

The Collapsible Bund is manufactured with a strong and durable stand design which can easily be folded and deployed. The stands are made with a durable marine grade batten to provide exceptional flexibility and strength. These battens ensure even if the bund were to fill completely, it would maintain it’s structure and hold the liquid. Stands can be driven over if the wall of the spill bund is collapsed. For added protection simply cover the folded down bund wall with a material such as an extra sheet of PVC. 

Other Features of Collapsible Bunds 

  • Portable Containment Bunds are designed for easy set up and can be stored compactly when not in use (storage bags available) 
  • Collapsible Bunds can be fitted with drain ports to provide pump out access (a solid bund is the safest approach) 
  • Materials are suitable for a wide range of chemicals including most hydrocarbons and many acids 
  • The Collapsible Bund can be easily cleaned in the instance of a chemical spill 
  • Designed as drive over bunding – simply collapse a wall to drive in or out of the bund 

As a permanent or temporary liquid containment bund, some common uses include tank bund, ISO tank bund, IBC bund, drum storage bund, generator bund and 20′ or 40′ container bund. Virtually any type of container or equipment could be stored in the bund when used as a secondary containment option to be compliant with AS 1940. 

To make them even easier to use, the Collapsible Bunds can be supplied with a: 

  • Ground mat to increase their durability in harsh environments. 
  • Liner for added protection against punctures or harsh chemicals. 
  • Repair kit to keep you operating in the case of a puncture or small tear. 
  • Carry bag to make it easy to move and store the bund (carry bags suitable to lift on fork) 

These spill containment bunds and accessories are reusable so long as they are in good repair, properly cleaned and properly stored.

How to Choose the Right Size of Collapsible Bund 

These portable spill containment berms can be manufactured to any size to a maximum of 20m x 15m. Here are some tips to choosing the size: 

  • Increase the spill bund capacity or make a smaller footprint by choosing a higher wall. Options are 300mm or 500mm high. 
  • Think about the footprint. The portable bund will be 1m wider and 1m longer than the internal measurement. A ground mat will require a little more space to the bund footprint. 

Remember to leave space to: 

  • Walk around inside the collapsible bund if necessary. 
  • Fold down a wall for forklift loading the bund. 
  • Give cranes ample clearance to drop in contents. 
  • Open doors (such as a container door which swings out in a semi-circle). 
  • Attach hoses to equipment or vehicles inside the spill bund. 
  • Add a pump for draining the liquid containment bund.
