We have had our cellar converted, and the builder put in one of these
Its been concreted in place, and our builder has layed chipboard, and then plyboard, ready for flooring. He has cut a square shape out of the board so you can lift it out to get to the pump etc.
I intend to put 600 x 300 slate tiles down, so my thinking is that I need some form of manhole cover (preferably hinged) so I can get access when needed, but I want to be able to still have the area covered in the slates.
Where should I look?
