Thanks Horton, paving expert had a great run through and diagrqms for rigid paving which I followed but it wasn't quite as clear for flexible. I'll have another look...

Hi

Just a little pointer for you regarding the installation of any paving / flagstones, more so the costly natural products.

Apply slightly diluted PVA to the underside of the product to prevent the cement being drawn through the slab causing terrible unremoveable staining, this will be visable if not applied within 3-5years, deeming the product to age prematurly and become dull.

Should you choose to lay on a 5 spot system then the size of the spots will show on the surface of the product, again complete waste of time and more importantly clients money.

I should hope you dont choose to lay on a 5 spot system as it is considered a 'cowboys' way of installing and will only lead to loose and wobbling flags in the near future. The correct way to lay is with a FULL bed so the whole flag is supported to A) spread the weight evenly when trafficed on and B) to stop burrowing insects nesting in crevices and C) to stop water creeping underneath and freezing thus 'popping' the flag off the bed.

50mm full wet bed all day long for me, and the troops. my last comment was based on the fact that some installers choose the 5 spot system, incidently would cost an absolute fortune should they have priced for the brush in and hose down m joint compound.

As i stated a complete waste of time and money

Again thank you, have just handed in hard landscape project and used 50mm of moist sharp sand (consistency should hold a fist of sand which maintains it's form when hand relaxed) with a 150mm sub base. Flags brushed over with fine sand which I believe sets hard within a a few months to stop 'intrusions'. The end paving stones on either side were fixed with a concrete haunch (GEN 1 slump 10). Any other ideas also welcome ...
