My partner and I are about to hire a contractor to pour new asphalt on our driveway and parking lot. My question has to do with edging. I have read up on Permalock which is an aluminum edging that requires 10" spikes nailed into compacted ground. It will be more expensive and we'd have to wait for it to arrive from out of state to our home. I was wondering if I could use 2x4 or 2x6 pressure treated lumber instead. I know it won't last as long as aluminum but will it at least give me ten years or so? Or is this just a bad idea?
I have a neighbor who installed landscape pressure treated timbers along the edge of his paved (brick pavers) driveway. His are holding up very well. I was wondering if I could do the same with an asphalt driveway.
