McBreen Environmental specialise in Bund Testing nationwide. Bund testing is fundamental because a bund provides containment for tanks or drums in the case of a leak. It is therefore important that bund testing is completed before it enters service, then assessed for integrity regularly thereafter.

Integrity assessment of newly built bunds
We carry out Hydrostatic Bund integrity testing 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. Where there are valid safety or practicality issues a Chartered Engineer carries out a visual inspection.

Assessment by Hydrostatic tests
We fill the bund with water and measure the drop-in water level 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 could 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.

In addition to bund integrity assessment, McBreen Environmental also offer advice on Tank and Manhole integrity and firewater integrity assessments.
