We also offer sprinkler reservoir cleaning, maintenance and refurbishment services
AtNordicSub, we don’t stop at the inspection – we also offer complete solutions when problems are detected in a sprinkler reservoir. We have experience with everything from underwater cleaning and rust removal to installing sacrificial anodes and renovating tanks, both with and without draining.
We solve problems – not just discover them
When we detect sediment, corrosion or biological growth during inspection, we provide the followingspecializedservices:
Underwater cleaning with divers and suction equipment
Using underwater vacuuming and diving teams, we can effectively remove sludge, leaves, dirt and other deposits from the bottom of the tank – without emptying it. It’s a gentle and quick solution that ensures continued operation.
Rust removal and anode installation
Rust under water can lead to serious damage. Our divers perform manual rust removal and install zinc anodes (sacrificial anodes) that protect the tank structure from future corrosion. This is an effective, preventive solution that extends the life of the tank.
Empty tank cleaning and refurbishment
When it’s necessary to empty the tank completely, we offer full cleaning and surface treatment. We can also help with epoxy coating, welding or sealing cracks in the tank walls and bottom.
Complete renovation and maintenance
Whatever the condition of the tank, we can plan and carry out a complete refurbishment to bring it back to full compliance. This includes both underwater work and work inside empty tanks.
