I have recenty embarked on regravelling my work drive. I have had quotes in access of £10000 and cannot afford that so have decided to do it myself. I have started digging, cleaning and basically trying to even out the lumpier bits of the drive. It looks ok but there are some definite soft patches where the water pools when it rains. I am wondering what I should do next. The main part of the drive is very hard but the edges where the cars tend not to park is quite soft. It has boudarys of a brick wall on the front and side, paving slabs on back and a tarmac on the other side.I have a rough idea how much gravel I need (5 tonnes) but also want the prep to be right. Any help would be much appreciated.
