Hi all,
I am new to the forum, and it is proving to be both very interesting and a fountain of knowledge, thanks to the regulars for keeping it all going and to the posters for the interesting content.
I am renovating a cottage, and have had a replacement solid floor put in the original part of the house, 100mm of hardcore, 100mm of concrete. The house has been recently extended and the extension has the same floor makeup, however, the level is slightly lower in the new extension.
I plan on using a liquid screed throughout both rooms.
As there will be a new doorway from the original house room into the extension, and I am running flooring straight through I need the finished floors to be eventually level.
The structural engineer has specified 100mm of insulation throughout, which of course I could add too to make up the difference in height. What is the minimum insulation thickness for a concrete floor?
The main problem is that the extension floor is uneven as well. it slopes from 65mm down to 85mm lower than the existing part of the house.
In my head I have a couple of options, however I am inexperienced in this area:
A: Bump the insulation up in the extension to compensate as close as I can, and then have a screed in at a thickness that will make up the difference.
B: Sort out the level of the slab before the insulation goes down.
What would be the best plan of action for remedying this?
Thanks in advance for the replies!
