It may not drain at all - if the soil is higher than the paving, and it's poorly drained or clayey, then there's nowhere for the water to go. Try as we might, we've not been able to get water to run uphill! ;)

I'm not familiar with your particular layout, but I would suggest that you need some form of channel to direct the surface water to a collection point, such as a gully or outlet to a soakaway. Simply leaving a gap between adjacent edging units could cause water to drain ONTO the pavement from the garden, rather than t'other road round!

Is the garden particularly well-drained or is it heavy going?

What about putting a dispersal drain at the back of the edging, and then leaving 15-20mm gaps, as you described, between adjacent edgings, which will allow the water to escape to the drain?

Dispersal drains are illustrated on the Land Drains page.

I can't say what the best drainage solution would be as I don't know the layout of your project, but with two existing drainage points adjacent to the house, then a linear drain could well be the best solution.

Just how linear drains are connected to an existing system depends on the type of linear drain and the type of existing system. Some have special fittings, some need a new connection while others can be butted up to an existing gully or rain-water pick-up.

I'd need a photo or an annotated sketch to help you decide the best way to proceed.
