Sod grass should be installed along straight edges such as patio, fence and driveway edges to achieve power leveling. New turf needs time for its roots to connect to soil and establish themselves before any traffic passes over it. Final grade should correspond with existing pavement or sprinkler heads, and be watered frequently so as to prevent drying out too rapidly. Rake, compact and water as soon as soil becomes compacted for best results. Get to know about this sod power leveling in the link.
