Hi
Recently moved into a 1930's detached. To the rear there are two bay windows and to the side an extension put on in the 80's. All along the rear and extending round one side of the house is a york stone patio in crazy paving slabs.
The pointing is generally in poor condition but more worryingly the paving comes up to the level of the DPC. As far as I can tell the DPC is slate. The DPC on the extension is higher than that of the original house and also of modern bitumen roll type material.
The depth of the patio averages about 2 metres and along the lawn edge of the patio are two walled raised beds. And old step made up of two courses of brick leads up between these raised walls to the lawn. So, the lawn is quite a bit higher than the level of the patio. The garden then follows a gentle slope up away from the house.
The option to remedy the patio proposed by the surveyor was to basically remove it and lay a new patio 150mm below the DPC. Obviously this is a lot of work/money. I will have to rework the patio anyway as it is quite rough but I am keen to reuse the original stone.
There is a single downpipe from the roof to the rear with empties into a standard square hopper. Directly inline with this hopper, and towards the middle of the patio there is a small circular drainage grate. I am not sure if this drain connects to the gully from the downpipe. I would expect the rain water drain to empty into a soakaway somewhere in the back garden. Is it likely that the small drain from the patio empties into a common pipe to this soakaway?
Any suggestions greatly appreciated. Only previous experience was laying a small circular patio in my old garden flat a few years ago now.
Thanks
