Who made repairs to tank bunds?​

Answer 1

Answer:

Prior to applying any Bund lining or protective coating in a primary or secondary containment tank or area over an existing structure, it is always necessary to first inspect and where necessary then carry out repairs to any visible damage or cracks in the concrete surface. Otherwise these can be reflected through the newBund Lining and render it useless, as the liquids that are intended to be contained could penetrate and attack the structure, or escape and contaminate the area.

The idea of leaving any unsound or damaged concrete or masonry in place, followed by overlaying this with a build-up of a fibreglass system insitu that has unfortunately managed to become a ‘standard’ approach for many less technically competent contractors, is not normally an optimum solution. Covering up structural damage, che,ical attack and deteriorated concrete base slabs and walls is never a good idea and may be a huge risk and future liability for you and your company (individuals are also now held to account as being liable under the latest legislation on environmental pollution and also Health and Safety requirements. This is because the future structural integrity cannot be ensured and there is the potential for further unseen deterioration and possibly wash-out and void creation beneath the fibreglass layer.
