Installing a block paved manhole cover

Hot dipped galvanised recessed manhole covers can be used to hide existing manholes, block paving is fitted inside to continue the pattern of the surrounding paving.

The cover is bedded into place using a 3:1 mixture of sand and cement making sure its at the correct height and fall, this can be acheved by using a tight string line from one side of the drive to the other and adjust the height to suite, haunch both the inside and outside of the manhole to hold it in place

Brush kiln dried sand over the blocks and tap lightly on the top of the blocks using a block of timber and lump hammer to vibrate the sand into position, the manhole lid was removed from the frame to put the sand in place as extreme care should be taken to avoid any sand getting in between the cover and the frame

The finished manhole cover is now placed in position, once its completed all you see in the 4 corners are the heavy gauge lifting eyes to accept standard profile lifting keys which are used to lift out the cover

    I’m wanting to replace a manhole in my outhouse with a recessed covered one. I’m just a bit unsure what you mean when you say “haunch both the inside and outside of the manhole to hold it in place”. What’s haunching?
