Google's telling me that polymeric sand stops weeds because it amalgamates into a solid that's impermeable to water, if that's the case, I can't see why that would be exempt from planning permission.It is my understanding that use of polymeric sand eliminates much of the weed problem.
Not for long, mine turned into a nursery for every weed going within a few years. Sweep it with a broom, and you're left with a couple of barrowloads of loose tarmac to dispose of, and don't put ramps, jacks or axle stands on it unless you want holes poked in it.Tarmac is the best maintenance free solution
It amuses me how much aggro people will put up with rather than just use maintenance-free concrete that lasts a lifetime.
