Crumbly channel across concrete floor before recarpeting


Postby Zacccc » Sat Jul 16, 2016 9:19 pm

I've just taken a carpet up prior to putting a new one down. The floor is concrete but a channel has been chipped out at some point to lay a gas pipe. The problem now is that where the channel has been concreted after laying the pipe some of the concrete is now crumbly and has come out, leaving the channel 1 to 2cm. deep in places. Has anyone any suggestions as to how to remedy this? It's not deep enough for a bit of concrete mix, and plaster would just come out when walked on. Thanks.

Do you know whether self leveling compound will take damp proof paint over it? At the sides of the room the concrete floor has become crumbly through a bit of rising damp. So where I've raked out the loose pieces I want to use self leveling compound to make the floor level to the wall and then paint over it with damp proof paint. Or would it be better to paint the concrete first and then put down the self leveling compound?
