How best to edge my patio - Using sandstone cobble/sets??

[Andirockx]

Hi fellow landscapers/DIYers,

I am laying a Indian Sandstone patio with a complimenting border of sandstone square sets 50mm deep. I have laid the patio on MOT with a full bed of mortar 30-50mm think.

Ideally I want the border to lead straight onto a lawn (which ill be laying next).

My question is what is the best method of securing the sets to avoid them being dislodged when moving when trod on? I have haunched the sets near the house as I am back filling with stones but don't want to do this on leading edge as the grass will not grow. Ideally id like to lay the lawn straight up to the patio.

Any advice / ideas gratefully received.

Thanks

Andi

It's usual to haunch on the grass edge as well - the grass still grows as the haunch doesn't go that far under the lawn.

Thanks very much for your reply George.

I had had the thought of using a rope effect edging set into the ground with just the rope top showing. This would also provide a feature and neat edge to lay lawn up to. Are there any negatives of doing this?

I'd assume the soil of the other side would keep the edging in place?

It would be better to use a natural stone edge with natural stone paving - over time as the concrete weathers, the sandstone will show the rope top edge up a bit. Also, the edge will undoubtedly topple over at some point if it's not held in place on both sides. You could use a round top edging in natural stone or a bullnose step tread used vertically if you're looking for a slightly raised border.

You'll also find that using the haunch method that George recommends, you have a perfect mowing strip (if it's needed), and avoid presenting a trip hazard.

Thanks for your advice guys. Haunched it in the end and forgot about the concrete rope edging. Very good point about the difference in materials.

Next job... Pointing/grouting!
