Chemical Bund Linings

Chemical Bund Linings provide a cost-effective solution for sealing and protecting concrete surfaces from chemical attack in the event of a chemical spill.

Chemical resistant epoxy linings are relatively simple to apply and can resist attack from a variety of commonly used industrial Chemicals and are proven to protect against:

  • Diluted Acid Solutions <20%
  • Alcohols such as Ethanol
  • Alkalis such as Sodium Hydroxide and Ammonia
  • Most Food Products
  • Excellent resistance to most Hydrocarbons such as Styrene

Chemical Bunds are generally used around storage tanks or drum storage areas where flammable or toxic liquids are held, alternative measures may be the use of sumps and interceptors.

It is normal to limit the number of tanks in a single bund to 60,000 m3 total capacity. However, incompatible materials should have separate bunds. Tanks often have individual bunds. Bunds should be sized to hold 110% of the maximum capacity of the largest tank or drum. This will allow some latitude for the addition of foam during response to the emergency. Bunds are generally fabricated from brick/mortar or concrete but where liquids are being stored above their boiling point additional insulation, e.g. vermiculite mortar, may be added as cladding to reduce the evaporation rate. 

Maintenance of bunds is an important aspect, often overlooked, particularly in remote locations. A system of inspection should be in place to ensure the integrity of the bund. Also due consideration should be given to drainage to allow the removal of rainwater.  Failure to remove rainwater will reduce the capacity of the bund and may result in overtopping and if the substance to be contained is incompatible with water e.g. oleum, may result in an increased airborne release. Consideration of these scenarios should be included in the Safety Report. for more information: www.hse.gov.co.uk
