Has anyone any experience of permeable paving on a driveway? The sort of thing we've seen online is a sort of plastic grid which grass is supposed to grow through, in the pictures it looks lovely and less harsh than Tarmac/block paving but I don't think I've ever seen any in real life. I also have visions of the grass not growing so basically being left with a driveway made of lumpy plastic.
Our drive slopes quite steeply towards the house so anything which encourages water to sink into the ground rather than swoosh downhill and pool around the front door would be good.
Any thoughts welcome!
