Hi All
We inherited a raised patio when we bought this property. It's surfaced with those big old 3'x2' concrete flags and has a low point in the middle where water tends to stand after heavy rain. Its not so much of a problem in the spring and summer, but in the winter when the rain is more persistent and the water table rises it can take days rather than hours to drain away.
It strikes me that rather than taking up these very heavy flags and resetting them to create a fall, it would be easier to install channel drainage at this point to take the water away. Something like this:

Couple of questions prior to installation. I intend to cut the channel with the flags in situ rather raising them, due to their significant weight (I have a dodgy back). First, are these things designed to fit together or do you need to buy connectors? Second, do they need to be set in concrete for stability or would it be OK for them to be laid on the clay subsoil?
The plan is to attach 110mm pipe to the end of the channel via an outlet and drain the water onto a lower part of the garden.
The garden is heavy clay, hence over the last few years I've had to address numerous drainage issues, but this is the only part of the garden where I still have a problem, albeit a fairly minor one.
Any advice welcome, thanks.
