In 1997, Covac were asked to inspect a large Hornsley Bridge, Sectional, Steel Potable water storage tank, located internally in a roof top plant room within a Hospital in the North West of England. In order to comply with regulations, a Risk Assessment was completed on the tank, where the following problems were identified:
What did we do?
These images show the internal surfaces of the water tank, following draining of the tank.
These images show the tank, having been prepared by means of dry abrasive blasting techniques. In order to gain safe access and egress, we removed one of the steel panels from the bottom of the tank, which was later replaced with a new low level hatch. This meant easy access / egress for future maintenance and cleaning.
These images show the internal surfaces of the tank following the full application of Solvent Free Polyurethane Coating 165PW by means of Hot Applied, Plural Component Spray Equipment.
In summary, the tank was fully relined and protected against any future corrosion and leakage and access and egress was no longer a worry for the Site Engineer.
A Ten Year Warranty was provided with this work, along with an image supported Completion Report.
