Swimming pool - Laying granite copings onto epdm

[mickavalon]

I've asked this before, but thought I'd try again. We are building a Swimming Pool, and we're currently lining it with Firestone EPDM liner(Rubber). Part of the spec involves laying Granite Copings to 4 areas, on top of the liner. The Copings are approx 600x350x50mm, bullnosed and pre-cut to form 4 large Arcs.
My problem is nothing sticks to the Liner, as it's obviously non porous. Spoken to a few tech guys at Keystone(who supplied the Stone) and Ultracrete and they're scratching their Heads. Has anybody got any experience in doing this, i.e maybe a smaller water feature etc.
We have built loads of Smaller features, Carp Pools etc and generally rely on the weight to keep the edgiing in place(usually large Rocks/stones) or if its more formal, a couple of courese of Bricks/blocks.
The copings will, once finished, also form a maintenance "Walkway" around the edge of the Pool!!

Just free thinking but could not cantilever the anchor point so it's off the liner say with like wall plate strap then lay them on something like epoxy resin expensive but effective and then bed the paving rd them on sbr so they can go back and the straps hold them from falling into the pool. epoxy about £7 a mastic tube size so £7 a slab but I bet it would stick but you would need to check there was no chemical reaction.

Does it have to sit on the liner can't the liner be folded/tucker out the way

Does the liner sit onto a block or concrete skin/ formwork?

Our pool is block laid flat with a waterproof render lasted 20 years,

could you not sew in some chicken wire mesh to the edge with stainless steel tie wire, or plastic ties the sparks use?

The Copings sit under water seperating the swim zone from the Planted shallows, so they are permanatley under water. We have to use a liner to allow for the shape of the shallows and Passive solar gain to warm the water. Im thinking of speaking to Instarmac and see if thay do anything, or go down the epoxy resin route, which will chew a big hole in the budget. We need to limit the amount of Cement in the Pool or speed up cure times as well, because the Pool is Fresh water, and doesn't like chemicals.
