Secondary containment areas are designed to capture spills of oils, chemicals, or pollutants from primary containment tanks or vessels, helping to protect soil, vegetation, and groundwater from contamination.

Government and local authorities have a strong focus on the enforcement and protection of our environment therefore it is important you consider the correct solution in this process.

There are two main requirements for protective coatings in contained bunds.

Waterproofing the bund is critical for the protection of the environment, it is essential contaminants are contained. Secondly is protecting the substrate from chemical attack which is aggressive to concrete and steel the core components of the structure.
