Are there Brit standards for expansion joints in concrete with UFH and zones?There are none, manufacturer only says typically there should be and builder who fitted UFH etc says its screed suppliers fault!
Thanks, yes I thought as much, probably more to appease the customer who asked about them whilst not wanting to nip a pipe! Shouldn’t there be full joints in slab if heating is zoned?
Hi all,
Ive been asked to lay limestone to a new extension, it has a main room 11 x 5m with smaller rooms off.
At present no expansion joints in slab and they say they are going to grind 8mm deep joint in middle of room and in doorways!
In my mind 8mm won't achieve anything ? I am proposing...
