First post, please be gentle.
Just put in a concrete base for a ground floor room 3.8m x 3.8 m or there abouts.
The plan then is to put 100 mm kingspan then a chipboard floor on top.
Unfortunately the floor I put in tapers from the middle to at worst 30 mm down at one edge (Not all wat round) less mostly.
So it isn't even.
Is this too much of an un even floor to carry out the above plan?
Thanks for any help and advice.
