How to make a driveway up 5 percent incline?

The Key is in the base you build. Incline is fairly irrelevant. Make sure you dig a foundation at least 12 inches deep, and fill with hardcore (broken bricks etc) to a depth of 4 inches. Set the hardcore into the earth with a lumphammer then fill to a depth of 8inches with sub base. Run over the whole lot with a compactor (whacker plate) then cover to a blocks depth with sharp sand. Run your compactor over the sand until it is nice and flat. Finally you can add your blockwork.setting it using a rubber mallet.

Be sure to dig trenches around the edges of your drive and fill with concrete to stop it from subsiding to the sides.
