Hello everyone, we are in need of some sound advice on a dilemma we cant get 100% answers to, we are having a single storey extension and knocking out the back wall and dining room wall to form one large open kitchen/living area.
We intend to fit wet UFH to the new part of the extension but we are concerned about possible expansion/contraction between new slab and old slab leading to the failure of 1000mm x 1000mm x 6mm porcelain tiles which will cover the entire floor space including old and new!
We have been advised to use a reinforced screed and use an uncoupling membrane and flexible tile adhesive so the tiles don't crack or lift, do we need to lay an expansion joint between the old and new slabs too as this would ruin the clean effect we are looking to achieve?
Many thanks in advance,
Paul.
