Found 2nd Mar 2010
We are in the process of getting our drive blockpaved. The builder has found what he calls a french drain at the bottom of our drive which slopes down towards the road. At first he thought it was a damaged water pipe and i duly asked the local authority to investigate - he now seems to think its not a problem and plans on block paving directly over it. We are concerned. Is he fobbing us off? Please help if anybody can!

It may depend on which type of french drain is there and on the slope of the drive and drainage facilities outwith the driveway. if there is a decent slope and roadside drainage then any surface water should just run off and be collected on the road. If not you may be liable to ponding and standing water.

What is he putting below the block paving, i.e. is he putting a layer of plastic sheeting below it?

I think you need to make sure once the drain is paved over it that it is still functioning as well as it will most likely be taking surface water to a nearby water course and check with the council that you have their permission. Just in case they need to do maintainence to it and tell you they need to dig it up

never seen plastic sheeting go down before block paving.

probably put down type 1 mot, then sand, then blocks. will need to go down around a foot minimum.

if drain is below this then no problem. if it is within this depth and was previously open, then need to find out if it was actually draining surface water
