Hi there. Thinking about doing my own block paving drive and I know I need to provide drainage for rain water. The driveway slopes from the road to the garage so ideally, a drainage channel along the garage threshold connected to a soakaway would be perfect but my problem is, one side of the driveway is fenced and the other side is a garden wall so I've nowhere to actually put a soakaway. This must be a common problem with driveways and any info would be great. Thanks.
