Driveway drainage

Question

I’m having driveway installed in front garden there’s been a retaining wall put in and the driveway will be on flat ground after being excavated, it’s approx 4.8mx4.8m and there’s a lot of water gathered in the area now.  Will this area need drainage or will it be ok once the type 1/sand and monoblock is done?

Hi
You need drainage
you need a drainage system because over time due to the rains you will always have water

If there is a problem now it won't go away later ... You should have a soak away that is made for the size of the driveway with a ACO drain along the property wall connected to it 
the drain system has to be as far away from the road as possible hence along the property 
Or you can have a resin driveway on pervious compacted concrete and no more problems with rain water collection as all the surface is permeable as long is done properly 
this is the only driveway that is fully in accordance with Planning 
hope this help

Hello bud I would advise you to install some aco drainage system out it before you do your paving as it’s all you want is water sitting on your pavin as it will wash away the aggregate and all paving starts moving or dropping I’m only being honest bud you want to create more exspence later on when you can resolve the issue now

You would normally put a land drain to the bottom off retaining wall and waterproof membrane behind retaining wall then obviously weep holes to lower section of the wall then  any water should run off the drive way or to surface water drains

I would advise to install an acco drain on the area along the front of retaining wall, with a discharge in to a soak away if there is no main’s drainage. This will relieve any future problems occurring.
