Daewoo Construction and Engineering (DCE) engaged ICC to supply the products specified and the required plural component equipment directly to the project site.

Treatments were applied in various locations within the project which included;

• Primary Containment of Process Basins,
• Secondary Containment of Chemical Storage Bunds and
• Waste Water Process Tanks.

The largest application area was the chemical treatment and neutralization demi pits, which were completed in ten working days.

All three pits were fitted with a series of brackets to support process pipe structures. This was recognized as a critical area for the application works. A site specific detail (pipe termination wrap) was designed and utilized to ensure that the coating was properly terminated at pipe brackets and other penetrations.

Two secondary containment bund areas were also coated, to ensure that Sulphuric Acid and Caustic Soda were properly contained should spills of leaks occur. This consisted of one bund area for caustic soda tanks and one bund area for sulphuric acid tanks.

Chemical attack and differential thermal expansion rates can cause failure of jointing systems allowing corrosive vapor or liquid to ingress under the tank. Corrosion can then progress rapidly, leading to perforation and leakage with associated environmental damage, tank repairs costs and lost production.

ICC was involved from the specification phase to implementation and completion phases, which included the following; full specification and detail design, product and application equipment supply, project management, quality assurance and inspection program development and management, and specialist coating application teams.

ICC completed the project within the desired timeline and exceeded all expectations of the client. On completion of the project the client and contractor engaged ICC again for another scope of work that entailed 2800 m2 of primary containment coating for effluent pits.
