GPT conducts comprehensive bund surveys in line with relevant legislation and guidance, designed to assess the condition, suitability and effectiveness of your secondary containment.
Bund Inspections
Constructing high-quality bunds is only the first step in effective pollution prevention. Ongoing maintenance and inspection are critical to ensuring bunds remain functional, compliant, and capable of providing the necessary secondary containment. As environmental legislation becomes increasingly stringent, regular surveys are essential for maintaining compliance and safeguarding your site.
Our bund surveys are designed to assess the condition, integrity, and suitability of your bunds. Surveys can be conducted as a one-off assessment or scheduled at regular intervals - recommended annually based on seasonal temperature changes.
During each survey, we evaluate the compatibility of your bunds with the types and quantities of liquids stored, ensuring that they continue to meet legal and operational requirements.
Our bund surveys will inspect:
Following each survey, GPT will provide a detailed report outlining the condition of all inspected bunds. This includes the identification of any defects along with recommendations for necessary remedial actions. Should repairs or upgrades be required, we can also provide quotations for our specialist services to bring your bunds back to full compliance.
Our reports can serve as third-party validation to external auditors, including those conducting ISO 14001 audits, demonstrating that an effective bund maintenance and inspection program is in place.
All inspections are conducted in line with applicable regulations and best practice guidance, such as The Control of Pollution (Oil Storage) (England) Regulations and CIRIA C736.
For clients seeking to conclusively verify the watertightness of their bunds, we offer hydrostatic testing. This involves:
Should defects be identified during testing, we will also provide recommendations and, if requested, quotations for necessary repairs.
While hydrostatic testing identifies the tightness of the bund, it can be time-consuming and is unlikely to identify point loading failures or potential catastrophic failures. As an alternative or complement, GPT offers structural analysis conducted by qualified structural engineers. Using both manual calculations and TEDDS software, we can evaluate:
Our structural analysis provides robust evidence that your bunds can maintain containment integrity under expected conditions, without requiring intrusive or disruptive testing.



Bund Maintenance
Following a bund survey, it is essential to carry out any recommended repairs and implement a clear maintenance schedule to ensure long-term performance and compliance. Our secondary containment services take care of this for you, giving you peace of mind that your bunds are functioning effectively and meeting regulatory requirements.
