As most industries strive to maximise available floor space, it has become essential for Chem Resist to develop the ability to have close proximity integral bunds with their storage tanks.

Where there are no immediate height restrictions, building tall and keeping narrow enables the creation of large ‘tank farms’ with minimised footprint.  This has already allowed numerous clients to grow their business, without the acquisition of additional premises.

A direct benefit of reducing the tank diameters is the reduction in Civils costs by using less concrete.  This in turn has a positive impact on carbon footprint for the organisation.

Chem Resist’s Integrally Bunded Storage Tanks are recognised as ‘Bunded’, using definitions from Ciria ‘Containment systems for the prevention of pollution’.  A bund is ‘a facility (including walls and base) built around an area where potentially polluting materials are handled, processed or stored, for the purposes of containing any unintended escape of material from that area until such time as remedial action can be taken’.  Bunds are structurally independent from the primary containment tank.

During manufacture, both the storage tank and bund are fabricated independently, both comprising of their own cylinder and base.  A welded rainskirt prevents ingress of water if the intended location is external.

In contrast, it must be noted that ‘double skinned’ or ‘double walled’ storage tanks whereby both ‘skins’ or ‘walls’ are sited and welded to the same base, are not considered to provide secondary containment and should not be classed as bunded.

Chem Resist’s Integrally Bunded Storage Tanks range from 1,000 to 100,000 litres, varying in diameter to suit your requirements.  All are bespoke products and designed individually to BS EN 12573.
