What’s Involved in Paving a Commercial Parking Lot?

A properly paved parking lot starts well before the first drop of asphalt is poured. At William Stanley & Sons, we follow a proven process to ensure lasting quality:

Site Evaluation & Estimate

We assess your property, usage needs, drainage requirements, and layout for parking spaces.

Excavation & Grading

Proper grading ensures your lot won’t suffer from puddling or structural failure.

Installing the Base Layer

A strong gravel foundation supports the weight of traffic and ensures stability for the asphalt layer above.

Asphalt Paving

We use commercial-grade asphalt mixes and industrial compactors to install a smooth, durable surface.

Line Striping & Signage

From parking stalls to ADA compliance, we’ll make sure your lot is fully marked and ready for use.

Sealcoating (Optional)

We apply a protective layer that guards against water, oil, and UV damage—extending the life of your investment.

Why Choose Asphalt for Commercial Parking Lots?

Asphalt paving is the go-to material for commercial parking lots—and for good reason:

  • Fast installation means less downtime for your business.
  • Cost-effective pricing compared to concrete, especially by square foot.
  • Flexible surface that holds up well to weather changes and traffic stress.
  • Smooth appearance for improved curb appeal and customer safety.
  • Easier repairs when damage does occur—no need to repour the entire lot.

When properly installed and maintained, an asphalt parking lot can last 20+ years with consistent performance.

How Does Proper Drainage Impact Parking Lot Longevity?

Drainage is one of the most overlooked—but most critical—factors in lot paving. Poor drainage leads to:

  • Standing water that weakens the asphalt
  • Premature cracking and potholes
  • Unsafe conditions for pedestrians and vehicles

Our team carefully grades and compacts every parking lot to ensure water drains properly—protecting your investment in the long run.

How Much Does It Cost to Pave a Commercial Parking Lot?

The cost to pave a parking lot depends on multiple factors:

  • Size of the area (typically priced by square foot)
  • Site prep requirements (grading, demolition, drainage fixes)
  • Thickness of the base layer and asphalt
  • Add-ons like curbing, striping, or sealcoating

That said, asphalt remains one of the most cost-effective materials for large-scale paving, especially over time with regular maintenance. We provide clear, detailed estimates up front—no hidden fees, no guesswork.

FAQs About Commercial Parking Lot Paving

How long does it take to pave a parking lot?

Most projects are completed in 1–3 days, depending on the size and complexity of the job. Striping and sealcoating may add a day or two.

How often should I sealcoat my asphalt parking lot?

Every 3–5 years is recommended to protect against water damage, oxidation, and general wear.

Can you pave around curbs, drains, or existing structures?

Yes. We’re skilled in working around site elements and ensuring everything ties in cleanly and functions properly.

Do I need to close my business during paving?

Not necessarily. We can often phase work or pave in sections to minimize disruption to your business operations.

What happens if water pools in my parking lot?

Standing water leads to premature damage. We can assess and correct drainage issues through regrading or installing proper slopes during the paving process.
