floating laminate across 2 concrete floors
We removed a stud wall and were suprised that it did not sit on a massive concrete floor. Instead the floor is 2 - one for each room (as it was) now a single room but 2 floors separated by a piece of wood.

I'm worried about expansion - also the level needs some slight work I think. I will bash down the edges and check for level. If it is level can I ignore this 8 inch wide channel filled with wood, just laminate across it as I am looking to make a single floor.

If it isn't fully level will a self leveling compound fill over everything and be able to change the differing expansion rate of the wood and the concrete.

Thanks :no:

If there is wood between the 2 slabs of concrete, the wood needs to be remove. This is a good place for termites to enter your home. If you could load afew pics of the floor we my be able to help.

Here you can see both rooms and then the 2 concrete floors separated by the gap and wood which must serve some purpose ?

Is this a slab home? I don't understand why the wood is there. If there is nothing under the wood I would cut it out and add rebar then concrete.

Apparently it's called a baseplate and is normal under stud Walls in the uk. If I use a self levelling compound with latex milk and not water it will expand with more give. Cracks won't be a major concern due to the floor hiding them.

I am not familiar with this type of building. In my area untreated wood is never placed next to an exterior wall at ground level or below. We have lots of termites that love wood. If you have no concerns with this then floor leveler with a latex additive is the way to go. Good luck with your laminate.

Thanks woodman, if we had any termites they would be welcome to eat this now redundant piece. But yes agree what you say.
