I'm planning to pave a patio with a drain cover in it. I need to raise the drain cover to the same height as the slab. The drain cover is a Hepworth cover 340mm square, the pipe inside is 300mm dia. Any advice would be appreciated. Thanks

Have the taken it off yet? The cover is simply the square top piece with a cylinder and foam sealing ring on the bottom. This all fits within the risers of the chamber which are a fractionally larger diameter.
Therefore often you have enough extra to simply pull it up a little and as long as the foam is still forming a seal simply rebed the cover on some concrete at your desired height.
If not simply fit a riser ring on top of the existing rings and cut it down to whatever depth you need to add.
