m coating - M-COATINGThis no-entry coating technique allows circular and rectangular shafts to be cleaned and coated using an automated spin cast method of application. A fully automated centrifugal spray unit coats shaft walls to any required thickness. The system is suitable for concrete access chambers and wet wells. It is a safe method of coating shafts as no personnel are required to enter during the coating process.


A rotating cleaning nozzle is connected to a high pressure water pump delivering 39,000kPa (5600psi) to enable thorough cleaning of the walls prior to coating. Coating is then applied using an integrated, fully automated system consisting of a mixer, pump and a centrifugal spray head. The centrifugal spray is guided up and down inside the shaft using a gantry mounted winch at a constant, controlled rate to enable the design thickness of mortar to be applied in several passes. The number of passes will determine the final coating thickness. Mortar can also be applied overhead to platforms and to benching when required.


The M-Coating system is suitable for concrete structures from 500mm to 3000mm in diameter.


The M-Coating system is suitable for a range of corrosion protection mortars including normal and calcium aluminate cement and aggregate mix.
