Manholes are an important part of a sewer or drainage network, they allow access for inspection and maintenance however their own maintenance is as important as the rest of the network. If manholes are not correctly maintained in a serviceable condition they increase the risk of infiltration, allowing unwanted groundwater in to the network and in extreme neglected situations can collapse and cause disruption to the network and general public.

Therefore maintenance of manholes and chambers is as important as the network of pipes in a drainage system. As well as the traditional solutions of repair, DrainsAid have an innovative solution for the up keep of manholes and chambers.

If you require any manhole rehabilitation or maintenance service, please do not hesitate to get in touch. From our base in Wakefield we can cover the whole of Yorkshire including Leeds, Bradford, York and Sheffield.

Hermes M-Coating System

The innovative Hermes M-Coating System used in conjunction with ERGELIT dry mortars is the perfect technology for manhole coating and has been a proven method of rehabilitating corroded and/or leaking manholes since 1999.

The M-Coating system is a solution that can be used on a wide range of applications including tunnel maintenance, bunds, culverts and any other surface or structure that requires a protective coating.

The process is computer controlled from the surface, allowing operatives to work outside the chamber with minimal entry requirements.

The manholes are cleaned using the integral dual rotating high pressure jets on a computer controlled, automated winch, leaving a firm surface for the M-Coating ERGELIT mortar to bond to.

The M-Coating process is based on an integrated system consisting of a mixer, a pump and a centrifugal spray. Once cleaned the high pressure jetting head is replaced with a centrifugal spray head to apply the M-Coating mortar to the walls of the manhole, again controlled remotely.

The computer controlled centrifugal spray runs at 5000 rotations per minute and operates until the pre-determined coating thickness is reached
