Grading & Base Preparation
Build the Right Foundation for Long-Lasting Asphalt
Proper grading and a compacted aggregate base are what keep asphalt driveways and parking lots from settling, cracking, and holding water. Nexus Asphalt Paving & Sealcoat prepares driveways, parking lots, and private roads across Auburn Hills and Oakland County for smooth paving and reliable drainage.
What We Do
Grading & Base Prep Services
We shape, stabilize, and compact the subgrade so your asphalt has the support it needs. Our crew focuses on drainage, load-bearing strength, and clean transitions to concrete, curbs, and existing pavement.
Site Grading & Drainage
We set elevations and slopes to move water away from structures and prevent ponding on the finished asphalt. Proper grading is critical for new asphalt driveway installations and parking lot paving projects.
Subgrade Stabilization
Soft or pumping areas are corrected with undercutting, stabilization, and proper material placement to reduce future settlement.
Aggregate Base Installation
We install MDOT-approved aggregate base stone for the application and thickness.
Compaction & Proof Rolling
Compaction is verified to help prevent ruts and cracks. Proof rolling helps identify weak spots before paving begins.
Why Base Prep Matters
Most asphalt problems start underneath the surface. A properly graded, compacted base improves performance and extends pavement life. Most asphalt driveway failures happen because of poor grading or inadequate base preparation.
Better Drainage
Correct slopes reduce standing water and freeze-thaw damage.
Fewer Cracks & Settlement
A stable base helps prevent dips, alligator cracking, and edge failure.
Smoother Finished Surface
Uniform support means cleaner grades, transitions, and curb lines.
Built for Traffic Loads
Base thickness and compaction are matched to cars, trucks, and commercial use.
Grading & Base Prep FAQs
Common questions from homeowners and commercial property managers planning a paving project.
Do I need grading if I’m repaving an existing driveway or lot?
Often, yes. If there are low spots, drainage issues, or edge failure, regrading and base correction helps the new asphalt perform better and last longer.
How do you prevent water from pooling on asphalt?
We set proper pitch and drainage paths during grading and base shaping. The goal is to move water off the pavement and away from buildings.
What base material do you use under asphalt?
Base materials vary by site and traffic loads, but typically include properly graded MDOT approved aggregate installed in lifts and compacted for stability.
How thick should the base be?
Thickness depends on soil conditions and use (driveways vs. commercial lots). We evaluate the site and recommend a base section designed for the expected traffic.
Can you fix soft spots before paving?
Yes. We identify weak areas and correct them through undercutting, stabilization, and recompaction so the asphalt has a solid foundation.
Do you handle grading for new construction paving?
Yes. We coordinate grades and elevations so the finished asphalt ties in cleanly to garages, sidewalks, curbs, and storm drainage features.
