Petrochemical (PETR)



Floor Problem Areas (FPA)


Customer Location:

South Carolina


Application Date:

July 2012


Application Situation:

Concrete floor in a Chemical Process Building



Floor, sumps and support pedestals are eroding due to sodium hypochlorate exposure to the concrete. Additionally, the sump drain has PVC which is a fire hazard and must be replaced. Chemicals will seep through the concrete into the ground if not contained.



Belzona 5811 (Immersion Grade)





Application Method:

Power wash and remove any loose concrete, remove the previous epoxy from the sump containment well. Concrete was pH tested prior to application of material. Followed the IFU for Belzona 5811 as to cure and overcoat time. Belzona 5811 was applied in two coats with a roller and brush system.


Belzona Facts:

Adhesion and protection from sodium hypochlorate was the princial reason Belzona 5811 was selected. The customer had a previous coating on the sump well floor and sides that delaminated and failed due to poor adhesion.
