Useful to have a guide to supersede the venerable APN12!
I'm not sure about the way it deals with uneven ground though, by piling up sharp sand or clean angular aggregate to fill in the dips. (par. 17, p9). A colleague of mine (who has laid acres of the stuff) recommends laying the geocells directly onto slightly uneven land and levelling *above* the cells, and where there are deeper hollows, using thicker or doubling up the geogrid, as in the diagram attached. It seems to make good sense to me to put the additional stone *above* the protective layer, not below it.

A free download of the document is available on the Arboricultural

I hope that you find this guide to be informative and of assistance.

Best regards,
