SPRINKLER TANK REPAIR - BELFAST An ROV inspection of this fire sprinkler tank in Belfast was carried out at the instruction of our clients insurance company. The 10 year inspection showed that the mastic jointing at the panel joint seams had perished and that the Z purlins supporting the roof and vortex inhibitor were severely corroded. Our client stored a lot of combustable materials on site, consequently their insurance company insisted that this fire water tank should be in good condition and be ready for action should a demand be made on it. The glass enamelled 'fused' internal wall surfaces were still in excellent condition. So we only needed to make repairs to the vertical and horizontal panel joints. Before any applications were made we keyed the surfaces by abrasive grit blasting. We always want to apply systems that we can guarantee watertight. So it was an easy decision to encapsulate all the vertical and horizontal bolted panel joints with a fibreglass lining system and apply a zinc rich cathodic coating system over the steel work. This picture shows the full encapsulation of the sectional panel joints using our guaranteed watertight fibreglass lining system. It was a bit wet, cold and windy in Belfast when we were there in November. We needed to hire in an indirect diesel heater to keep the temperature inside the tank above 5c. Thanks to HSS for all there help in sourcing and supplying.
