Secure liquid containment with bund linings systems are needed for the primary and secondary containment of water, chemicals and oils in many industries, such as waste management, power generation, food production and aviation. The failure of these bund liners can result in the release of toxic and dangerous substances into the ground and surrounding environment.
In recent years the Environment Agency and SEPA have passed laws requiring that all oil and chemical storage facilities have a secondary containment vessel, commonly known as a bund, in place. These vessels are required to hold at least 110% of the capacity of the largest tank, or 25% of the overall storage capacity when multiple tanks share a bund.
Guardians of Fluids: The Essential Role of Bund Linings in Achieving Secure Liquid Containment
Traditionally, concrete or masonry structures were used to form the bunds, however these are vulnerable to attack and breakdown over time, causing cracks and leaks. A specialised lining system is therefore needed to prevent such failure and to provide an impermeable coating which can contain any spills or leakage from the tank or container inside the bund.
Fibreglass GRP linings are ideal for bund lining, forming a highly chemically resistant barrier that can protect the underlying surface from all major kinds of attacks and is also non-corrosive. This type of lining is designed to work for decades, even in harsh industrial environments with high chemical attack and exposure. The lining is fully compatible with the most common lining materials such as epoxy, polyurethanes and vinyl esters, and can be applied to concrete, steel, timber and masonry substrates. The linings are also fully compliant with all regulatory inspection requirements including a visual inspection, together with low-level hydrostatic testing.
