Bund Lining

Many bunds require specialist linings to protect their structure from the aggressive chemicals and oils they contain. Without proper lining, these materials can degrade the bund walls and floor causing failures.

Bund Lining / Bund Relining

When storing aggressive chemicals, such as acids, within a primary container, it is essential to line the bund with an appropriate, resistant material. The lining serves to protect the bund structure in the event of a leak and enhances the watertight integrity of the bund. For instance, concrete bunds housing tanks containing caustic soda must be coated with a lining resistant to caustic soda. This ensures that, in the event of a leak or catastrophic failure, the bund remains durable and effective in containing the material.

Bunds may require relining if structural defects, such as cracking or leaching, are identified. Selecting the appropriate lining is critical to maintaining a secure and compliant bund. We specialise in the assessment, identification, and application of bund linings to ensure optimal performance and regulatory compliance.

Our experts will conduct a detailed risk assessment to determine whether lining, or stripping and relining, is necessary and select the most suitable materials accordingly. Relining is often a cost-effective alternative to complete bund replacement, especially for bunds built with unsuitable materials such as breeze blocks.

Bund relining extends the lifespan of your critical infrastructure, through the application of specialist protective coatings and linings. Our effective, economical relining solutions are designed to protect assets from the damaging effects of abrasive and corrosive substances within the primary container. By tailoring each application to your operational needs and site-specific risks, we deliver robust, proven protection against asset damage.

Bund Lining Considerations

There is no universal solution when it comes to bund lining systems. Each application requires a tailored approach, with careful evaluation of several critical factors to ensure long-term performance and regulatory compliance, including:

Chemical Compatibility & Storage Conditions: The specific chemicals to be stored - and the manner in which they are stored - must be carefully assessed. Bund lining materials vary in their resistance to different substances, and an otherwise suitable system may become ineffective if exposed to incompatible chemicals or storage methods.
Structural Condition of the Bund: The existing condition of the bund structure is another important consideration. Factors such as previous contamination, substrate integrity, surface cracking, or the potential for structural movement must all be considered to maintain a fluid-tight seal.
Spill Response & Maintenance: Response time and clean-up protocols can also influence the appropriate choice of lining. Some systems offer enhanced resistance at the expense of other properties such as ease of repair or application. Proactive sites with immediate spill response capabilities may have more flexibility in product selection, whereas remote locations may require more robust, chemically resistant systems due to delayed response times.

Our solutions support the repair, maintenance, and extension of asset life by delivering durable protection that restores integrity and enhances longevity. These solutions are always developed to ensure full compliance with regulatory requirements, helping you meet both environmental standards and operational obligations with confidence.
