Tarmac is terrible stuff. It looks pretty for a short while when it's new, but i's not long before it starts disintegrating and sprouting weeds. Things like jacks, axle stands and car ramps sink into it too. Once it's crumbling you can't even sweep dirt off the drive without having to find somewhere to dispose of a couple of barrowloads of tarmac.Alternative is red or black tarmac with option of various types and colours of chippings rolled into the surface
If the driveway is more than 5 square metres in area you need planning permission to re lay it with an impermeable material. If it's already an impermeable material and you're just replacing like for like then you're cool, but i'd take lots of photos of the old one to CYA in case its questioned. A woman at t'other end of the village had to dig up her new embossed driveway which she'd had laid without permission to replace her gravel one.
No, very quite.
As I mentioned in my previous post, that applies to impermeable material, ie, concrete, resin, etc. Last time I checked gravel was not impermeable.
