installing pavers at property line

Pavers have to have edging, even more critical on driveways. The 6" extension of gravel base is correct, but who knows what a neighbor might do in the future with your 6" extension and the edging fastened into his yard (like putting in a fence, digging for a pipe). Have you thought of doing a concrete curb as edging - either exposed or concealed? Details courtesy of Belgard:

Also if you ever want to put a fence keep the driveway back 6" from the prop line anyway.
