Our teams are working tirelessly to help secure and maintain drinking water supplies, ensuring clean and safe drinking water is provided without interruption to critical services such as our hospitals as well as the general public. Now more than ever, the safety and wellbeing of our staff is of the utmost importance and we have adapted our safe working practices to ensure social distancing precautions are in place and that the correct hygiene practices are being followed. Making safety is our priority, and we endeavour to make sure everyone at Stonbury goes home safe to their family.
With limited funds available towards the end of this AMP period, we were asked by our client to develop a refurbishment proposal that would cost effectively extend the life of the 2 tanks by a further 5 years.
Whilst the lower levels of the steel tanks were in reasonable condition, the higher levels had such severe corrosion; holes had appeared within the steel plates effectively reducing the operating levels within.
A repair proposal was formulated utilising a 100% solids Urethane hand applied protective coating system, incorporating fibreglass matting embedded in epoxy adhesive, to cover all areas damaged by the corrosion.
All extruded bitumen jointing compound was removed, by hand scrapers, from all panel joints and bolt heads.
The internal faces of the tanks were then grit blasted, using the quill dustless blasting system, to remove surface corrosion and expose further damaged areas.
All prepared damaged areas were then overlaid with fibre glass patches embedded in epoxy adhesive.
All joints, bolt heads and patches then received 2 full ‘ stripe’ coats of the urethane protective coating, after which the full internal area received 2 further coats of the system.
