Hi, I have set a 1200x900x25mm thick natural slate slab as a hearth which is going to be surrounded on 3 sides by 10mm thick x 600x600mm porcelain tiles. These are on a concrete floor and I previously made a 15-20mm recess in the concrete to allow the 25mm thick hearth to sit lower so that it will be flush with the tiles when they are laid. There will be a log burner sitting on the slate. My question is should I just allow for a 3-4mm grout joint around the slate where the tiles will meet it or should there be an expansion joint? Thanks

Should be ok to just grout the joint. What did you fix the slate with? Is the concrete substrate crack free?

I think you have to have a hearth on top of the tiles don't you like this ? I could be wrong

Just needs to be visually different from the tiles I think, not necessarily raised.

Hearth only needs to be inflammable and extend 300mm beyond the stove, doesn't have to be above surrounding flooring.
The HETAS website will have the correct spec if my memory is fading...

Hearth Regulations for Log Burners. SIMPLE and EASY to follow... - http://www.stovefittersmanual.co.uk/articles/hearth-regulations/

As usual you can interpret regulations to suit your needs...

I would say a distinct colour change would denote the hearth edge.

Good man paul
One thing though , one rule which cannot be broken under any circumstances, is when wood burner is fitted and lit, you must sit in front of it with acold beer and admire your handy work

But you must never be close enough to make your beer warm!!

Red wine has different regulations of course!

Thanks for the advice guys. A few weeks away yet before I can have a glass of red and a mince pie in front of the stove but something to look forward to.
