A Bund Wall Lining is a barrier around a primary storage vessel to prevent spills or overflow of hazardous chemicals, oil and fuel. They’re essential in protecting both the environment and workers in the event of a tank failure, but they can also be vulnerable to damage and deterioration. This is especially true if the right lining solution is not selected, installed and maintained to suit the chemical environment. This can lead to expensive site contamination, environmental harm and breach of Environment Agency guidelines that can result in fines.
There are many different types of bund lining available, and the one to choose depends on your requirements, the environment and the type of chemicals you’re storing. Fibreglass and epoxy bund linings are both durable, but the choice of material is important as they can differ in their resistance to chemicals and installation process.
Seal Smartly: A Guide to Choosing the Right Bund Wall Lining System
Maintaining the integrity of bund walls is key, and signs to look out for include a build-up of plant or weed growth, cracks and moisture penetration. In addition, it’s vital to ensure that all pipework penetrations are correctly sealed as a poor quality sealant can introduce corrosion sites at bund penetrations.
If a bund wall lining is damaged, it’s important to repair it as quickly as possible, in order to avoid contamination and leakage. At Prokem, we provide fast and effective repairs using specialist resins that are suitable for the type of chemical stored. These include glass fibre mat and catalysed unsaturated polyester (UVP). This method is applied in sections with a foam roller, and the concrete is then coated with the resin to fill any surface imperfections and create a smooth, solid finish.
