Chemical and Petrochemical Containment
Tank farms can range in size from huge complexes in refinaries to clusters of tanks used to store heating oil or product ingredients in relatively small facilities. They all need to contain a material that is spilled or leaked before it gets into the groundwater supply. The geomembrane liner should be made from material that will resist damage caused by the tanks contents.
Bund lining materials must have a chemical resistence suitable for primary containment of the stored product plus the strength and other required resistences for long term exposure to the atmosphere where the bund is located (as the bunds stand empty all their life). Chemical resistances must include rainwater and other localised contamination.
Aquadam UK Ltd have UK and overseas experience in bund lining and have carried out retro-fitted below tank linings when a liner is fitted below a tank after it has been jacked up.
