A finished commercial lot should drain cleanly, carry the traffic it sees every day and look sharp for customers and tenants. That comes from the grading and base work as much as the asphalt on top.
Grading and drainage
The lot is graded so water flows to the catch basins rather than sitting in low spots, where it softens the base and breaks up the surface. Getting the grade right is what keeps a lot flat and dry for years.
Designed for the load
Truck routes and loading areas need a heavier base and thicker asphalt than car parking. Each area is built for what it will actually carry.
