I was recently introduced the the concept of drainage paving accomplished by laying thin stone vertically into bedding over a gravel drain. The pictures I saw were very attractive and while the concept seemed simple enough, I have been looking to be directed to a source of additional information or to those with experience in this area. Can you help? Thanks

I've only ever seen this used in gardens. John, as the labour element is quite high compared to throwing is a perforated land drain and backfilling the lot with a clean gravel.

To be honest, I've never seen a proper construction drawing for this type of drain, but we built one for a client in my village following the instructions from a book on garden design he had been reading. I can't recall the name of the book, but if I see him in the alehouse tonight, I'll ask if he still has it. All I can remember is that it was a 'coffee table' type book on building a Japanese Garden and featured many photos and descriptions, including the ever-popular 'deer-scarer' yoke for water features and a really elegant downspout arrangement for small roofs that consisted solely of a length of chain!

For the drain we built, we used stone roofing tiles bought from a salage yard and filled the interstices with a 6mm local river gravel. The whole affair was about 450-500mm deep with a half-perforated clay pipe at the base which was then linked to the existing SW system of the property. If memory serves me right, we used 6 tiles, each around 30mm thick, and the overall width of the drain was about 250mm. It was used at the edge of a paved patio and was only about 4.5m in length.

As far as I know, it's still working. I'm sure that if there had been any problems with it, I'd have had my ear bent long before now! ;)

thanks for rhe response. I would be most appreciative if you learn something from your your pub friend.

No sign of him last Friday, John. I'll see if he's in this Friday. I know he travels abroad on business quite often, so he might be away.
