Portable Containment Bunds.

For temporary activities where the risk moves — refuelling plant, maintenance and servicing, deliveries, decanting, and equipment standing on unmade ground.

They are also used as emergency containment, deployed around a leaking container or under a damaged tank while a permanent solution is arranged.

Foam-wall bunds that collapse under vehicle wheels and spring back, drive-over models for plant, rigid frame bunds for static use, and inflatable or self-rising wall types for larger footprints.

Choice depends mainly on whether vehicles need to drive in and out, and how quickly it must deploy.

Capacity is stated per model and varies widely. Size it to the realistic release — for refuelling that is typically hose contents plus a margin; for a standing IBC it should be 110% of the container.

Note that a bund used outdoors accumulates rainwater, which reduces the available volume over time.

Modern PVC and polyurethane bunds are robust, but they are consumables rather than permanent infrastructure. Grit, sharp swarf and repeated folding all shorten life.

Inspect for punctures and seam separation before each use — a bund with an unnoticed tear provides false confidence, which is worse than no bund at all.

Rinse off fuel and chemical residue, dry fully, and store folded loosely rather than tightly creased. Damp storage promotes degradation and mould at the seams.

Contaminated rinse water must be treated as hazardous waste, not tipped onto the ground.

They can, but they were not designed for it. Sustained UV exposure degrades the material, and standing rainwater accelerates wear and reduces capacity.

For permanent containment, a rigid bund or bunded store is the more economical answer over any reasonable timeframe.
