New formulation of PROTECTA-Mag coating proves successful at North East Water

Protecting Ageing Infrastructure

Justin Roth \ February 19, 2019

With a constant flow from 2 other pump stations, a sewer pump station at North East Water had suffered a significant amount of acid damage, with its concrete surface visibly pitted.

Calix coated the asset with the new formulation of PROTECTA-Mag, which allows better control of hardening time and improves adherence to the concrete walls. The new formulation proved very resistant to wear in flowing / splashingconditions. The application of PROTECTA-Mag involved no confined space entry and no network shutdown. PROTECTA-Mag prevents corrosion by raising surface pH, which neutralises acids and inhibits the formation of acid-producing bacteria.


Before and after application, the new PROTECTA-Mag  adhering well to the walls.

PROTECTA-Mag – treat the cause, not the symptom

With an emphasis on creating a sustainable future for existing infrastructure, Calix has developed a cost-effective, reliable and innovative solution to corrosion in ageing sewer
