Use Chatoyer’s collapsible bund capacity calculator to work out the minimum bund capacity for stored liquids, choose a suitable bund material, and configure a custom collapsible bund for your site. The tool is designed to help you plan secondary containment for drums, IBCs, totes, and tanks using the AS1940 guidance shown on the page, then send a quote request with your preferred size, material, and project details.
It helps you estimate minimum secondary containment capacity, choose a suitable material, and configure a custom collapsible bund for your site. The tool combines stored volume inputs, AS1940 guidance shown on the page, material selection, SDS upload, and quote request fields.
Use this tool when you need flexible spill containment for drums, IBCs, totes, tanks, refuelling areas, temporary storage, maintenance work, or project-based liquid handling. A collapsible bund is useful when a fixed solution is not practical, and you need a bund sized for your actual site layout, storage volume, and operating conditions. Chatoyer’s page is built for custom fabrication and allows multiple configurations in one quote request.
The calculator is suitable for sites handling liquids across industrial, construction, transport, utilities, manufacturing, mining, defence, agriculture, marine, and other operational environments. It can be used for indoor or outdoor planning, although the page notes that outdoor storage may require additional allowance for rainfall and freeboard depending on site conditions and regulations.
Step 1: Enter the liquid volume in litres and quantity for each container type you need to store. The page calculates minimum containment using the AS1940 rule shown on the site: the greater of 110% of the largest liquid volume stored or 25% of the total liquid volume stored.
Step 2: Select your chemical if known and review the material recommendation. You can also upload one or more SDS documents so Chatoyer can confirm compatibility. The listed material options are PVC 900 GSM, PVC 1370 GSM, and XR-5 1020 GSM.
Step 3: Enter your preferred internal length, internal width, wall height, material, and quantity. The configurator supports internal dimensions from 1.0 m to 20.0 m, height options of 300 mm or 500 mm, and lets you add multiple bund configurations to one quote request.
The page uses the AS1940 containment rule shown on the site: the greater of 110% of the largest liquid volume stored or 25% of the total liquid volume stored. You enter the liquid volume and quantity for each container type to estimate the minimum containment requirement.
Yes. The configurator specifically asks you to enter liquid volume and quantity for each container type, with examples including drums, IBCs, totes, and tanks.
Choose the material based on the chemical stored, the site environment, and the intended use. The page includes a chemical selector, a recommendation field, and SDS upload so Chatoyer can review compatibility. Available options shown on the page are PVC 900 GSM, PVC 1370 GSM, and XR-5 1020 GSM.
Yes. You can enter internal length, internal width, wall height, material, and quantity, then add multiple configurations to the same quote request.
No. It is best used as a planning tool to estimate capacity and prepare a bund configuration. Final compliance depends on site-specific conditions and applicable requirements, and the page notes that outdoor storage may require rainfall and freeboard allowance.
Yes. The page allows you to attach one or more SDS documents so Chatoyer can confirm compatibility for the chemicals you intend to store.
