Bund Testing

Bund testing is fundamental because the purpose of a bund is to provide containment for tanks or drums in the case of a leak. It is therefore important that bund testing be carried out before a bund enters service and then assessed for integrity on a regular basis thereafter.

Integrity assessment of newly built bunds
Bund integrity testing by means of a hydrostatic test should always be carried out on new bunds before they enter service.

Integrity assessment of in service bunds
For in-service bunds, the method of bund integrity testing depends on the regulator. In Ireland, the EPA’s preference is for hydrostatic testing unless there are valid safety or practicality issues in which case a visual inspection may be carried out by a Chartered Engineer.

Assessment by Hydrostatic tests
The procedure for hydrostatic bund integrity testing requires the bund to be filled with water and the drop-in water level to be measured over a defined period.

Visual assessments
Bund integrity testing by visual inspection entails the examination of the bund for cracks, holes, and other defects which may cause a loss of integrity. Examples of defects include exposed rebar, unsealed pipes passing through bund walls and unplugged shuttering bolt holes.

Where necessary McBreen Environmental can fill bunds with water and dispose of afterwards.
