Hi, I wonder if you can help I have a bit of a problem I have a terrazzo floor in my hallway, it has been covered in bitumen and I think this can be cleaned off easily enough. The problem I have is right through the middle of the floor a channel has been cut in the terrazzo to lay a gas pipe to the lounge, this has then been filled with concrete. I'm really not sure what to do I have been advised by one floor fitter that the floor would cost £15000 to lay now with terrazzo and so I would like to keep it really. Any suggestions!?? I am in Cardiff.
