The primary purpose of a Bund Lining Systems is to prevent groundwater pollution should the primary containment system – usually concrete, brick or steel – fail. They are designed to hold 110% of the capacity of the storage tank and if they are damaged by environmental contamination then this can have serious consequences.

The best way to protect a bund and make it a reliable form of secondary containment is to line it with a suitable Polymer-based lining system. Glass reinforced plastic lining (fibreglass lining) or Polyurea lining can provide this, and the added benefit of these is that they are also very effective in increasing the strength of the bund to resist mechanical damage from vehicles and pedestrians.

Demystifying Bund Lining Systems: Understanding Applications and Benefits

Solvent-free epoxy resin lining and coating systems are ideal for many bund applications. These systems have been developed to be sprayed on and cure rapidly, which is very useful when lining large areas quickly. They have been developed to be chemically resistant for durable performance and they are the most popular type of protective lining for bunds and other primary and secondary containment vessels and areas.

Specialist epoxy, urethane and polyurea-based lining systems have been developed to be very fast curing so that large areas can be lined and re-lined with very little downtime required. These systems are designed for high-level chemical resistance to ensure that they can withstand the most aggressive and toxic of chemicals. These advanced lining systems are often used as high risk cover containment liners for steel and concrete tanks in petrochemical plants.
