i've recently had an extension built. Builders being builders have done their job and left the garden in a mess( not complaining as this was expected). However the garden is not flat now and as a result when it rains i have alot of puddles forming around my outside walls. How can i keep this water away from my walls. I was thinking about laying gravel about half a metre wide and 250cm deep around the perimeter of the walls. What do you think. Any other ideas will be appreciated,
thanks in advance
