What is portable bunding

Portable Storage Bunds create permanent or temporary relocatable watertight bunds that can be manufactured to suit your site requirements. Portable bunding is a popular choice for CSG industry temporary site works and storage applications. Portable bunding is durable and easily folds away within minutes. All portable bunding is chemical, oil and fuel resistant.

Our portable bunds are manufactured using reinforced fiberglass battens to create edge stability that can be easily folded down or up. The Construction is HD PVC and has been UV treated and strip welding.

Designed for Australian conditions

Our PSB’s are made in Australia, designed for the Australian conditions

We fusion weld all joins for a 100% seal and test the product for any defect before dispatch. We can provision eyelets around the perimeter for fastening or pegging into place and a PSB can be installed within a few minutes. We can also optimise your bunding requirements by identifying key areas and risks and custom design a bund to suit your storage challenges on site.

Our portable bunding is heavy duty and can be driven into when the walls are collapsed. Alternatively, pallets can be placed inside the bund for forklift options.

We offer spill kits and absorbents to compliment bunds for incidental spills and can package containment and clean-up solution to suit your needs. If your project requires you to create temporary work sites and storage solutions then consider a PSB, you’ll like its durability and simplicity. Be compliant without impacting your time schedule.

+ Can we store fuel and chemicals in the one bund:
Always check the storage classification of the product you want to store. It should nominate how to clean it up if spilled and should also categorize it. The key is not to store two potential reactive liquids together in a bund. Always check with your chemical suppliers if you’re not sure on the products classification.
+ Would a PSB work as a drip tray for refueling machinery and equipment on site?
Yes it would. This is a good use and we recommend an HD construction for prolonged exposure to Hydrocarbon and that a spill kit or absorbent be used to clean up spilled fuel/diesel immediately before it creates a safety hazard on site.

+ How fast can I get a custom solution made?
Lead times are usually less than 7 days. We do keep some standard sizes in stock and its worth checking if you’re in a hurry.
+ Can you freight it to my site?
Yes, we offer full delivery to site, let us know where you are.
+ How do I clean a chemical spill?
Chemical spills can be dangerous and it’s important for you as an operator to understand exactly the type and classification of the chemical being stored at your facility prior to receiving them. Safety always comes first, contact your chemical supplier or study the product’s safety data sheets for a guide on the correct way to clean up a spill and ensure you’re prepared with the correct PPE. Trade Enviro supply HAZCHEM spill kits and absorbents, including hazardous waste bags for disposal. If you’re looking for PPE, we can help that too.

+ Is there a rule for capacity requirements with bunds?
Are you storing indoors or outdoors? Outside Bunds are subject to rain and you may need a bund closure system. You will definitely need a procedure including regular checks, spill prevention and response to manage the bunds. Calculations are usually worked on 110% of the maximum most likely spill that needs to be allowed in capacity. I.E. a 200L drum requires 220L capacity. Our PSB’s because of the unique design usually cater well over for most applications.
+ How do I manage a larger outdoor permanent bund in rain events?
We specialize in automated bund closure systems for permanent outdoor bunds. The FOX bund closure valve is designed to allow a bund to remain open so rain doesn’t flood the bund causing hazards on site. The system detects hydrocarbon and automatically shuts down, isolating the bund securing the spill within the bund. Best suited for concrete and fixed bunds, large-scale transfers and holding facilities. For automated spill control systems check out our spill response products.
