Picture below shows an alley way I'm planning to brick off. It'll then be knocked through to effectively enlarge the garage to the right (in the picture).
Red lines indicate where the single skin brick wall will be constructed tieing not toothing into surrounding walls.
At present there is no drainage solutions. Any surface water just runs down the alley and disappears. Very little surface water is ever seen - even after sustained heavy rain.
Bricking off may cause problems so I'm suggesting the following drainage from a small grate by the white door. Sunken gulley through alley, emptying into existing drain just the other side of the white gate.
Questions.
1) Would the channels above be suitable?
2) Would the brickwork be OK on top of the channel? If not, what would be a better solution?
3) Should the existing concrete groundwork be prepared in any way before brick laying commences?
4) What would be best to open up the concrete for laying channels? Angle grinder / pick / both?
5) Any other advice?
