Hi everyone,
As part of my refurb project to my 1935 house I've decided to replace the entire ground floor suspended timber floor with a solid floor. I'll have 100mm concrete then 100mm insulation with 50/60mm screed to encase wet UFH pipes. This will of course be on MOT, sand, DPM.
I've built a ground floor extension on the back so overall ground floor area is something like 80m2. Apart from the living room, the dinning room, kitchen and extension are open plan so I was wondering if i'd need to include expansion gaps somewhere in this enormous slab!
I've the same question regards the screed too. I know i need to run thin insulation round the perimeter but will i also need to have expansion gaps in that also? I wanted to go for the free flow self levelling stuff.
Before anyone replies saying this is an expensive solution there are numerous reasons why the timber floor needed to go, first one being it was pretty rotten in places. I've insulated internal walls with 70mm thermo boards so seemed daft having a freezing cold void beneath my feet only separated by 27mm of floor board. The timbers had also distorted over time where the house has settled so seemed like the best (albeit most expensive) solution.
Many thanks
