Belzona® Protects Against Acid Attack



Petrochemical (PETR)



Tanks and Chemical Containment Areas (TCC)


Customer Location:

Chemical Plant, Cheshire, UK


Application Date:

March 2003


Application Situation:

Acid waste sump



Hydrochloric acid was seeping into a nearby water course. The problem was tracked down to a sump which had a hole in it, hydrochloric acid was leaking through and eating through the underlying concrete.



Belzona 4311 (Magma CR1)

Belzona 4111 (Magma Quartz)





Application Method:

Application was carried out in accordance with Belzona System Leaflet TCC-9. Damaged concrete was rebuilt and levelled with Belzona 4111 before coating with Belzona 4311.


Belzona Facts:

Belzona was initially chosen because it was a long term solution that could be applied during the available 3 day factory shut down. The client was delighted with Belzona going the extra mile to complete the unscheduled works within the allowed time frame. The sump is still performing as expected preventing any further seeping into the water course.
