Bund Lining, Secondary Containment Specialists
A bund is also known as secondary containment. Its sole purpose is to hold 110% of the liquid should the primary containment fail. Most chemicals, all but water is hazardous to the environment should they spill, therefore installing bund linings is essential. Bunds are typically made of either concrete, brick, or metal. For example depending on the corrosivity of the chemical stored in the primary containment or storage tank.
Steel bunds suffer from corrosion issues from water, whilst concrete & brickwork are porous. Installing a Polymer based lining such as Glass reinforced plastic lining (fibreglass lining), Polyurea lining, or an epoxy lining is essential. Thus ensuring that the secondary containment can hold the liquid in the event of the primary containment failing.
3 commonly used bund linings
Fibreglass linings: These are used in aggressive chemical environments with harsh chemicals such as Acids and Alkaline. They are especially used in old bund installations where masonry-based substrates have damaged mortar joints etc.
Polyurea linings: These tend to be installed on new build bunds or those that have severe movement issues. They are also lacking chemical resistance, and do not offer the same chemical resistance as a chemical resistant GRP Lining. A Polyurea bund lining is more suited to an oil storage bund.
Epoxy linings: Typically used on steel bunds, Epoxy bund linings are not good for concrete or brickwork bund lining as the epoxy coating is susceptible to movement stress cracking.
What are the benefits of applying a bund lining?
- Bund lining, especially fibreglass lining and Polyurea lining offers fantastic structural integrity
- A life expectancy in excess of 25 years
- Hardwearing
- Easy to clean
- Visually appealing
Our lining systems can be applied to all types of bunds. These can range from a few square metres in surface area to 5000 square metres +. They also have the benefit of being applied all year round, even in sub-zero temperatures of up to -5 degrees centigrade.
Our team of specialist lining contractors will provide you with an excellent service. Most importantly we guarantee your bund will contain any fluids in the event of a catastrophic spillage or failure to your primary containment
As well as our linings having excellent chemical resistance, we also offer high temperature bund linings. These can tolerate temperatures of up to 120 degrees centigrade!
