I've just laid paving slabs around an existing pond with a 2 - 3inch pond overhang. I've mortared the joints where there is a base but my problem is what to do about the gaps between the unsupported overhang. I realy do want to continue the mortared joint to the slab edge any suggestion ?. My intial thoughts were to attach something under the slab to give a base for the mortar. I thought about gluing plastic for flexibility , metal would be fimer but with flex it might crack slab etc + it would corrode over time and stain..
The other problem I have is because the pond has a complex shape one overhang slab is not as well supported as I would like any suggestions ?

Gaffer tape (or duck tape) is your friend.

Bit late maybe to be useful to you now but what I do is clamp a length of timber under the overhanging edge of the slabs to be pointed. You can pack the mortar down tightly against the timber as it doesn't give. You can remove it as soon as the mortar starts to go off. Always remember to dampen the timber first and, when removing it, don't just pull it downwards, slide it sideways or else you risk pulling the mortar out.
