Hello,
i'm replacing old flagstones at my fron porch and around the side of the house, including steps.
i was on a great site paving expert but it doesnt give a definiative answer to my query.
I 'm laying 300mm x 300mm precast flags 40mm deep onto of hard cement (previous flags bedding layer) and according to the site i should screed a layer of unbound quarry dust or whin & grit.
But because i have steps to flag, i'm concerned that a loose bed would cause movement and eventually lift. Should I look for a bounded mix with concrete?
thanks
