A1 Asphalt Columbia paves commercial parking lots across Columbia and the surrounding Midlands. Churches off Two Notch, apartment communities along Augusta Road, retail strips on Sunset Boulevard, industrial yards in the Broad River corridor — each property gets a lot specced for its traffic, its drainage, and the way it has to function during the install.
Lot Design for Real Commercial Traffic
A commercial lot isn't a bigger driveway — the loads are different, the use patterns are different, and the failure modes are different. Delivery trucks, garbage trucks, and fire apparatus put concentrated loads on drive lanes and the dumpster pad that residential surfaces never see. We size the asphalt section to the actual traffic. Standard parking stalls in Columbia typically get a 6-inch compacted aggregate base with a 2-inch binder and 1.5-inch surface course. Drive aisles for delivery routes step up to an 8-inch base and 3-inch combined asphalt thickness. Dumpster pads, loading docks, and turning movements get the heaviest section — often a thicker asphalt mat or a concrete approach apron — because that's where wheel loads concentrate and where soft pavement breaks down first. Right-sizing the section at design protects the surface investment for the full service life.

Drainage, ADA, and Code
Midlands thunderstorms move serious water across a parking lot fast. We design positive slope into every lot — typically a 1.5 to 2 percent cross-slope or crown — and we tie into existing storm inlets, curb-and-gutter, or detention basins so water moves off the surface before it ponds. Standing water is the fastest way to wreck asphalt; it sits, soaks into joints and cracks, and undermines the base. ADA compliance is non-negotiable on commercial work. We meet current requirements for accessible stall ratios, accessible stall widths (typically 8 feet with a 5-foot or 8-foot access aisle), maximum 2 percent slope in accessible stalls and aisles, and signage placement. Richland County and the City of Columbia permit office both want to see these details called out on the plan, and we handle that paperwork as part of the project.
Phasing to Keep Your Property Open
Most commercial property owners can't shut down for a week while a parking lot is paved. We phase the work. On larger lots, we typically pave half the lot while the other half stays open for customer or tenant access, then swap and finish the second half. For churches we usually pave Monday through Friday so the lot is open for Sunday services. For apartment properties we work through resident parking by section, with notices and signage posted ahead of each phase. The phasing plan gets worked out during the estimate so you know exactly which areas are off-limits and when, and we keep your tenants, customers, or congregation informed throughout the job. Minimizing downtime is part of the design — it's not an afterthought.

Signs Your Lot Needs Replacement
An overlay can buy time on a tired lot, but some surfaces are past the point where resurfacing makes sense. Here's how to tell.
Alligator Cracking Across Drive Aisles
Interconnected cracking in the high-traffic lanes means the base is failing. An overlay will mirror the pattern within a season — full reconstruction in those areas is the right call.
Ponding Water in Multiple Locations
Standing water after rain points to grade problems that resurfacing won't fix. Replacement with corrected slope is the only durable solution.
Heaving or Settled Sections
Bumps where utilities crossed the lot, settled trenches, or rolling sections all indicate base or subgrade failure. These need to be cut out and rebuilt before the surface goes back down.
Lot Older Than 25 Years
A well-maintained commercial lot can run 20 to 25 years. Past that, even good sealcoat and crack-fill maintenance can't keep up with binder oxidation and base fatigue.
Our Parking Lot Paving Process
Every commercial lot we pave follows the same disciplined sequence, scaled to the property's size and use.
Site Evaluation and Quote
We walk the lot, evaluate the existing surface and drainage, review your traffic patterns and any code requirements, and provide a written quote with phasing options.
Demo, Base, and Drainage Work
Old asphalt is milled or removed, subgrade is checked, base aggregate is brought up to spec depth, and any drainage corrections are made before paving.
Asphalt Installation in Phases
Mix is laid in binder and surface lifts as the design calls for, with joints tied in clean. Phasing keeps approved portions of the lot open through the project.
Striping, Signage, and Turnover
Once the surface cures, we stripe stalls, lanes, ADA markings, and any signage curbs to current code. You get a written maintenance schedule for sealcoat and crack-fill cycles.
What Our Clients Say
"Long gravel driveway off Devine Street that had washed out twice in heavy summer storms. Their crew regraded the whole approach, ran a proper compacted base, and laid hot mix that's holding tight against the front porch line. After two seasons of August downpours, no rutting, no soft spots — just a clean black surface that drains the way it should."
