I had my large driveway block paved 8 months ago and after any substantial rain, large pools of water form in the same two or three areas, around the middle of the driveway. These can take up to four hours to disperse. My installer then fitted two small drains in the vacinity of the pools but these have had no effect as the water does bnot drain towards them. I believe that my installer is becoming a little tired with the problem and I am preparing myself for 'battle'. I would appreciate any advice on what preparations should have been taken to ensure sufficient drainage to the sides of the driveway!
It sounds as if the drive hasn't been set out properly. Normally the paving should be laid to a fall of 1:60 to 1:100 minimum and water would not have a chance to collect in slight irregularities if these overall falls are maintained.
You say that the installer has fitted drains but where do these drains run to ?
Most importantly, if the drive is at the front of the property and was installed 8 months ago then it must comply with new planning regulations introduced in October 2008 which state that rainwater must drain directly to the garden or into drains connected to a soakaway otherwise the construction of the drive should allow it to be permeable. If these conditions are not met then planning approval is required for the drive.
Normal paving is not permeable, due to the fines in the sub base and the laying bed becoming impervious after compaction.
