Bund are described as liquid containment facilities that prevent leaks and spillage from tanks and pipes, though sometimes any barrier is referred to as bunding. Frequently, the liquids in tanks and pipes are toxic, but bund lining is used to prevent the liquid from causing damage (either by force or its chemistry). If a large tank has a catastrophic failure, the liquid alone can cause extensive damage.
In many schools and factories there are bunds that range from holding chemicals to drinking water. Particular examples which receive specific attention in the UK, the rest of Europe and the USA are oil and fuel storage tanks and transformers at electricity sub-stations which are filled with oil for cooling and insulation purposes.
Properly built bunds have to be large enough and strong enough to contain the contents of an entire tank, though regulations require it to contain 110% of the content of the tank or container. When multiple tanks share a bund, the capacity is based on the largest tank.
One of the most common bund designs for large tanks is a concrete or masonry wall built off of a concrete slab. Concrete and masonry works very well for many liquids, but bund liners should be used to decrease permeability. They can lose their ability to contain fluids due to poor detailing of joins, cracking, chemical erosion, accidental damage.
MacLennan-LSE have a range of systems for repairing the structure of the bund and providing a lining which is resistant to most fluids including fuels, acids, solvents. One of these systems is the Polyprufe system.
MacLennan-LSE's system is durable, very elastic, will accommodate movement in the substrate and it does not become brittle in sunlight. The system is also used extensively for Tank lining, Silos, Reservoirs, Flat roof waterproofing, Basement Tanking and Pond Liners.
Upon completion of the installation of Polyprufe lining system, we provide a 20 year guarantee - we are that confident in our systems. Our reputation is for customer service. Our commitment is aimed at customer satisfaction. Contact MacLennan-LSE now.
