Bunded Storage Units for Drums, IBCs & Chemicals

How do I choose the right bunded storage unit?

The right bunded storage unit depends on the type and volume of liquid being stored, the containers you use and where the unit will be positioned on site. For most organisations, the key considerations are capacity, drum or IBC configuration, indoor or outdoor use, access requirements and the level of secondary containment required.

When comparing bunded storage options, consider:

• the substances being stored
• the number and size of drums or IBCs
• the total storage and containment capacity required
• whether the unit will be used indoors or outdoors
• how frequently containers need to be accessed or moved
• site security and access requirements
• whether a standardised solution is needed across multiple sites or departments

For larger or more complex requirements, Hazchem Safety can help you identify a suitable configuration for your site and storage needs.

Bunded storage for drums and IBCs

Bunded storage units are available in a range of configurations for drums, IBCs and mixed container storage.

For sites that need flexibility, Dual Purpose Bunded Storage Units provide options for storing both drums and IBCs within the same unit. This can be particularly useful where container types vary across departments, sites or operational areas.

When selecting a unit, consider both your current storage requirements and any likely future increase in capacity.

What bund capacity do I need?

The required bund capacity will depend on the substances being stored, the size and number of containers and the relevant environmental or site requirements.

Rather than choosing a unit based on physical dimensions alone, check that the containment capacity is appropriate for the intended use. This is particularly important when storing larger drums or IBCs.

Are bunded storage units suitable for outdoor use?

Many bunded storage units are designed for outdoor industrial environments, but suitability depends on the individual product specification and the substances being stored.

Where a unit will be installed outdoors, consider weather protection, security, access for loading and unloading, drainage risks and the condition of the installation area. Always check the product specification before selecting a unit for outdoor use.

What is the difference between a bunded storage unit and a spill pallet?

A spill pallet provides secondary containment underneath drums or IBCs, while a bunded storage unit usually provides a larger dedicated storage area with integrated containment and, in many cases, additional protection or security.

Spill pallets may be suitable where only localised containment is required, while bunded storage units are generally better suited to larger quantities, multiple containers or more controlled storage arrangements.
