The emergency spill pit was contaminated when the pickling tanks failed and released contents into the pit.

Spilt acid attacked the surface of the concrete to a point where all internal surfaces including much of the steel reinforcing had to be renewed/replaced.

 

 

Solution:
The contaminated concrete was removed by high pressure water blasting and new concrete was poured to re-establish the dimensions and restore strength to the pit.

The surface of the pit was then cured for 28 days. Once cured we applied a proprietary FRP coating (approx 3mm thick) to all exposed surfaces (approx 620sq/m) to protect the pit from any future spill.
