Apologies if this is a basic (or daft!) question...
I would like to change our current double concrete strip driveway to a gravel layout. I am puzzled about drainage as I have backfall from the road to the house and the downpipe from my garage roof is actually *inside* the garage itself, so I have no exposed drainage gullies on the outside of the house.
Do I need to install a new gully or can I allow surface water to drain through the gravel and sub-base?
Many thanks.
Drainage for a gravel driveway
If you're not having any problems with drainage of surface water with the current layout of the driveway, then changing to an all-gravel construction shouldn't present any new problems.
I'm surprised to hear that the garage roof drain lies inside the garage, and that you think you have no external gullies - I've not seen a house yet (at least, not one built in the last 150 years or so) that doesn't have some form of external drain!

I can't see any drain covers outside the house where the fallback is at its lowest point. However, I am yet to clear the gravel that sits between the concrete driveway strips, so I wonder if there's a covered drain cover there?
We haven't had any problems in the past, but I don't want to create any new ones :-) !
The downpipe that comes through the garage roof goes straight into the garage floor with no exposed grates.
