Water tank lining project recently completed in Plymouth on the behalf of a national water hygiene company.
The sectional galvanised steel water tank had been left offline and empty for over six month due to the water storage tanks existing butyl liner completely failing.
Our initial task was to remove the failed tank lining and safely dispose of it via a licensed waste disposal operator.
With the failed tank liner now removed, it became apparent that water ingress had occurred underneath the liner which had caused advanced corrosion in various locations.
After investigating further, our operatives also realised that the bolts used to hold the storage tanks internal supports in place had also suffered from advanced corrosion.
This issue had caused them to break away, which had an adverse effect on the structural integrity of the water storage tank.
Water Tank Lining Process
Upon discovering the failure of the water tanks solid support it was critical that the support was repaired prior to continuing with the tank reline.
Our operatives replaced the failed bolts with stainless steel bolts to secure the solid support in place improving the structural integrity of the storage tank.
With the solid water tank support now in place our operatives extensively prepared all internal surfaces, ensuring all corrosion deposits were completely removed.
All critical areas such as the storage tanks joints and seams were also reinforced and stripe coated with ES 988 DWPU polyurethane.
Our operatives were now in a position to apply the final two full coats of DWPU to all internal surfaces.
The tank reline was now complete and a final tank clean and disinfection was carried out prior to placing the system back online.
