Installation
Fixed covers are set/placed directly on the manhole/fitment. The coating is applied around the entire cover and then packed well. When the installation is complete, the cover must “lie” 5-lOmm below the other existing road.

Tips/Advice
Fixed coverings are only recommended to be installed in low traffic areas as fixed coverings cannot absorb settlements.

To increase the life of the cover/frame
Ensure that there is no gravel/stone between the cover and frame. Gravel/stone damages the cover and can cause the cover to start “wobbling” in the frame, which creates noise when the cover is operated. Any rubber seals/damper rings on the cover are checked to ensure that they are whole and clean and can then be lubricated with lubricant/grease for easier installation in the frame.
