Hi All,
Really hoping someone can help me out here...
I am in the process of renovating my small patio garden (approx 6m x 5m - terraced house). The main problem is that the garden slopes towards the house not away from it.
I have cleared the existing patio (nightmare) and with some more digging could probably make it slope away. However, the problem for me is drainage. There are two drains feeding into one manhole. The two drains are situated directly against the back of the house. Therefore, if I made the patio slope away from the house it would have nowhere to go - the surface water would just head towards the raised flower bed.
Perhaps this is why the previous patio sloped towards the house? Most sites advise that the patio should always slopw away from the house - but I was thinking of just engineering some drainage to cope with the fact that it slopes towards the house?
One solution I was thinking of would be to install a linear drainage running against the house wall bit like a driveway (between the two drains - please see diagram image). This way all water could collect in the gully and run off into one of the two drains? Is this sensible?
The other issue is that the immediate part near the house is all concrete. Is it safe to cut this - old victorian house - could it affect foundations (sorry! I am new to the outdoors thing!)? Also there distance between the manhole and the house is quite narrow but should be wide enough to accomodate the linear drain.
Anyone have any thoughts - much appreciated. I have attached a link to an image showing a rough plan of my garden.
Cheers,
James
