Premeable Granite Sett Paving?

I am working with a garden designer next week and part of the front garden design is a 6m dia granite sett circle (100mm cubes). I would normally lay this on the dtp1 base and mortar bed. I would then add suitable drainage points if necessary to comply with suds.However the designer wants the area to be permeable using a steel edge, mortared in place, a pearmeable base, sharp sand bed and Romex permeable jointing to finish.I can not see the setts staying in place permanently.Any ideas or experience out there?

  • You're right and it has been discussed. I'm sure it's going to be ok though (well 99%) as I posted the same discussion on Paving Expert. The honourable Tony McCormack himself replied and said it should be ok as everything will be held in place by the Everedge and bound together by the Romex. Apparently this is quite a common pratice in Germany.

    I wish I had spelt Permeable correctly!
  • Concrete the steel edge and haunch in a respectable manner, the depth of the concrete will depend on the depth of your dig, the concrete must be seperate and not be laid on mot, geo grid the base and infill with 20mm washed aggregate (200mm max), TWO passes with the compactor, then infill 50mm of 6mm washed aggregate, do not consolidate the 6mm. screed or plastic float finish the surface , install setts about 40 at one time and semi fill the 10-12mm joints with 6mm washed, finish entire proect and top up joints with 6mm. One pass with a rubber matted compactor , brush away excess 6mm.

    You will have no defects as long as your concrete perimeter is solid and does not allow the sub-base stones to "leak"

    Ofer please may I have a sample of your product, contact me for address
