It is over five
years since Environmental Efficiency published the first edition
of the Good Bunding Guidelines.
These guidelines were published following a survey
which found that many of the bunds in Ireland failed the basic water
retention test. The Good Bunding Guidelines were produced
Efficiency to help IPPC and waste licensed facilities understand
the requirements for effective bunding.
Interest in this document has been considerable with
many enquires from Britain and Northern Ireland. As a result, Environmental
Efficiency have completely rewritten the guidelines, made
reference to the latest legislation and have included new sections
on testing of bunds, identification of construction type - plus
examples of bund failure.
These guidelines are particularly relevant to site
managers in Northern Ireland where the requirement to bund all oil
containers of over 200 litres is mandatory since the start of 2011.
This now brings Northern Ireland legislation into line with that
The most common cause of bunds failing the standard water
retention test is the use of block built bunds rather than
reinforced mass concrete as required by BS8007 and CIRIA 163.
This is because block built bunds have poor water tightness
due to the porous nature of the blocks and leakage between
the blocks (see picture left).
In addition, block built bunds are prone to cracking with
Most site environmental managers accept that block built
bunds perform poorly.
However, their difficulty is to identify which bunds are block
built as often the blocks are hidden by a render of concrete.
This has now been addressed in the revised Good Bunding
Guidelines with a section on identification of the bund
