Re: Sandstone paving on concrete questions 3Mar 05, 2011 8:14 pm THanks for the reply bashworth. I will ensure I have some expoansion foam between the house and the concrete. What about expasion joints though the rest of the concrete? Are they needed? Thanks Luke Re: Sandstone paving on concrete questions 4Mar 05, 2011 8:42 pm No more expansion joints needed unless there are piers for a pergola or something similar, The Harder You Try - the Luckier You Get !

Re: Sandstone paving on concrete questions 7Mar 06, 2011 10:04 am Thanks for all your help bashworth. I have one last question regarding the use of motar to bed down the pavers. I see the motar is a 4:1 sand to cement mix. Do you need to apply anything to the paver it self or can you just put the paver down onto the motar bed? Does the paver need to be wet? Anything else I need to know about putting down sandstone pavers on a concrete base? Thanks again Luke Re: Sandstone paving on concrete questions 8Mar 11, 2011 7:40 am bashworth No more expansion joints needed unless there are piers for a pergola or something similar, Could you please elaborate on this? I understand from your comment that exp joints are only needed if there are piers? How and where should exp joints be placed? And are the piers reinforced and what size? In fact, what would be good design specs for the piers and slab? I suspect there would be some differences in case of a flat land, as opposed to land which slopes away from the house?

Anything else I need to know about putting down sandstone pavers on a concrete base? Thanks again Luke I think I noticed somewhere just yesterday that the bottom of the paver needs to be 'skimmed' with a thin coat of that mortar mix, ie. not just put mortar onto the concrete - but can't rememeber in whose installation instructions. Also read that natural stone tends to soak up moisture a lot, from underneath. So, was thinking - if not using concrete slab - can we still put the black plastic under the road base?? Or, for that matter, under the conrete too? My signature is distracting people from my wise posts ... Re: Sandstone paving on concrete questions 10Mar 11, 2011 11:45 am Basically expansion joints on small ground slabs are to ensure that expansion of the slab does'nt affect the adjacent structures. The joints needs to be against any fixed structure such as house walls and any brick piers. If the slab is just finishing at the edge of the garden you could go over 20m without an expansion joint. Most paving slabs when I was younger (you don't see as much paving these days its all pavers or Bitumen) were laid on 5 dabs of mortar and levelled with a rubber mallet. If the paver is damp it won't take the moisture out of the mortar as fast which can help while 'adjusting it' with the mallet. If you haven't got a mallet (which I would recommend) use a lump hammer hitting a heavy lump of timber placed on the slab. The Harder You Try - the Luckier You Get !
