Just had the garden of our new build turfed. The company who laid it have
worked for my builder for years. I've seen past work they've done and it
looks great. They rotovated the whole area about three times using a
rotovator towed by a small tractor.. Each time removing all the large stones
and builders rubble that came to the surface. Then they leveled it using a
"grading plate" on the back of the tractor and human powered rakes. Then the
surface was rolled using a vibrating roller. Any hollows were filled with a
mixture of sand and topsoil. Then the turf was laid. The problem has been
keeping it wet in this dry weather. Sprinklers going almost continuously.
