The primary function of a Bund Wall Lining is to provide secondary containment if the tank or vessel within fails. This is a legal requirement to ensure that the environment and anyone within is not contaminated by a major spillage. Correct assessment, installation and maintenance of the lining system used on bund walls, tanks and vessels is essential to achieving this. Failure to do so can lead to costly site damage and breaching of Environment Agency (EA) guidelines resulting in fines and impact to the business.

There are several lining systems available, with each being designed for a specific liquid and chemical environment. The choice of which to use is dependent upon the level of protection required, cost and installation method. The EA require that bunds be inspected on a regular basis and that any damaged or deteriorating bund walls are repaired as soon as possible. Cracked walls are a particular cause for concern – any visual cracks should be inspected immediately as the integrity of the bund is compromised.

Beyond Barriers: Exploring the Diverse Applications of Bund Wall Lining

The lining on the inside of the bund acts as a barrier between the stored liquid and the bund structure, protecting against chemical attack and deterioration over time. However, over time, this lining can also be subject to damage and abrasion. To combat this, a range of lining reinforcements have been developed to improve the strength and durability of the lining. These include fiberglass (GRP) systems that are perfectly suited to harsh chemicals, with good corrosion resistance and excellent chemical resistance. They are also far better able to cope with physical damage than epoxy linings.
