Run-off from driveway

    Hi all,
    Will be putting down gravel on the driveway & around the new house early in the new year & was wondering how you control run-off & prevent water gathering in pools.
    I've noticed some standing water in the 4-inch down behind the house following recent heavy rain (its taking a good while to soak away) - I think it might be just where the builders have discarded caked mortar, skimcoat etc but it set me thinking about how this could be avoided with the finished drive?

    I know when tarmacadam is laid, the contractors have to allow for a "fall" - but what is the story when you're just having loose gravel?

    Thanks as ever

    It sounds like the rainwater is not infiltrating the ground as fast as it falls. We had a similar problem a few years ago. We dug up trenchs and ran french drains/land drains surrounded in a coarse gravel. We then linked it up to a surface water AJ at the front of the house. It is easy enough to do yourself, site area pending. The drains and gravel are cheap too.

    yeah the most effective way is by french drain. but i would recommed that you spend a little extra money on creating a filteres french drain. this just involves lining the trench with geotextile (terram 1000) and have a perforated land drain pipe at the bottom of the trench leading to you drainage.

    the ideal material for the backfill is cl 505. its a large round gravel a which will withstand compaction so when you put your driveway in you will not see a sag
