Home Improvement Ideas From Let Me Build It!

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

The recessed cover showing the main area of the drive now completed

A 3:1 mix of sand and cement to form a bed for the paviors inside the manhole cover

Cover the total area of the manhole cover and lightly compact using a steel trowel

Using a notched piece of wood as a guide screed the total area making sure its perfectly flat

The semi dry cement bed has been screeded to the correct height ready to lay the paviors

Use a straight edge or piece of timber to line up the block with the surrounding laying pattern and start to place the full blocks into position

Mark and cut each of the pieces

The manhole cover with all the cut blocks 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
