Proper grading and base preparation are the most critical steps in any paving project. A driveway is only as good as what is underneath it. Harrison Paving handles all excavation, grading for drainage, and stone base installation to ensure your asphalt surface has a solid foundation that prevents settling, cracking, and water damage for decades.
South Jersey's diverse soil conditions — from dense clay in Gloucester County to sandy loam near the coast — require careful attention to base preparation. Clay soils retain moisture and shift during freeze-thaw cycles, causing driveways to heave and crack. Sandy soils may not compact adequately without proper aggregate. We assess your soil conditions during the free estimate and design the base accordingly, typically installing 6 to 8 inches of NJDOT-specification dense-graded aggregate compacted in lifts.
Grading ensures water flows away from your foundation and garage rather than pooling on the driveway surface. We design a minimum slope that directs water to appropriate drainage areas. Poor drainage is the number one cause of premature driveway failure in South Jersey — and it is entirely preventable with proper grading.
