[Barning]

Hi There,

My first post so be gentle :)

I am converting a barn and the warranty company have said they require a 150mm slab the floor is large at 13m x 11m.

My question is about expansion, what is the best way to accommodate expansion on a floor this size that is 150mm deep please.

Thanks
