Concrete water tank reline and refurbishment recently completed in Farringdon, central London.
The existing epoxy coating in both water storage tanks had began to delaminate and severely blister in numerous locations.
These issues had been highlighted in a recently completed legionella risk assessment which deemed both water tanks to be non-compliant with ACOP L8 guidelines.
The water tanks subsequently required a full refurbishment to address these issues.
It was critical that no disturbance was caused to the buildings cold water services while the works were carried out we therefore ensured each tank reline was completed individually.
This process allowed for one water tank to remain online which would continuously supply the buildings cold water services while our tank coating works were being carried out.
Our team initially extensively prepared all internal surfaces.
Ensuring the failed epoxy coating and all surface contaminants were completely removed.
Both water storage tanks were then repaired using a cementitious mortar system and sealed utilising an epoxy sealant.
The first coat of WRAS approved polyurethane was then applied to all surfaces and left to cure.
Once cured, our operatives were in a position to apply the second full coat of blue polyurethane to the same surfaces.
Finally, upon completion of the project our operatives disinfected the water storage tank and placed the system back online.
The entire process was then repeated for the second concrete tank.
