Preparing Your Asphalt for Hurricane Season in South Carolina

Hurricane season in South Carolina brings more than just wind and rain—it brings serious risk to your asphalt surfaces. Whether you manage a commercial asphalt parking lot or have a residential asphalt driveway, storm prep isn’t just for roofs and windows. Your asphalt needs attention, too.

At Blackseal, we’ve seen how flooding, standing water, and debris can cause costly damage to driveways and lots that weren’t properly maintained. Here’s how to protect your pavement before the storm hits.

How Hurricanes Damage Asphalt

You might think asphalt is tough—and it is—but hurricanes push it to the limit. Here’s what you’re up against:

• Heavy rainfall and flooding can erode the base layer under your asphalt, causing soft spots, cracking, or full collapse.

• Standing water seeps into unsealed cracks, expanding them over time.

• Falling branches and debris can gouge or puncture older, weakened pavement.

• Chemical runoff and oil stirred up by floodwaters can stain or break down unprotected surfaces.

The takeaway? Your asphalt needs to be in peak condition before hurricane season starts.

7 Steps to Prepare Your Asphalt for Hurricane Season

1. Inspect for Cracks and Damage

Small cracks become big problems when water gets in. Walk your property and look for:

• Surface cracks

• Alligatoring (cracked patterns like reptile skin)

• Low spots where water pools

Pro Tip: Cracks wider than ¼ inch should be filled before storms roll in.

2. Sealcoat for Extra Protection

Sealcoating acts like a raincoat for your asphalt. It prevents water penetration and protects against UV and chemical damage.

• Reduces water infiltration

• Prevents erosion of the surface layer

• Improves visibility for striping and markings

Schedule early! Spring and early summer are ideal for sealcoating in South Carolina, and spots can fill up fast.

3. Clean Your Asphalt Surface

Remove leaves, branches, and oil stains. Not only does this improve safety, but it also:

• Prevents clogs in nearby drains

• Reduces slip hazards when wet

• Helps you spot hidden cracks
  
  

4. Check Drainage and Gutters

Ensure water can flow away from your driveway or lot.

• Clear out nearby storm drains

• Make sure downspouts aren’t dumping directly onto asphalt

• Watch for low areas or depressions where water might collect

Pooled water is one of the biggest causes of asphalt failure after a storm.

5. Secure Loose Signage and Parking Stops

Strong winds can knock over or throw unsecured elements, which may dent or break your surface.

• Tighten bolts on signs and wheel stops

• Temporarily remove anything that could become a projectile

6. Re-stripe Your Parking Lot

Visibility is key during emergency conditions and after a storm when lighting may be poor.

• Fresh striping helps with evacuation, traffic flow, and ADA compliance

• Consider reflective paint for added safety

7. Plan for Post-Storm Maintenance

Even with preparation, hurricanes can still leave damage behind. Know your plan:

• Inspect your pavement once it’s safe to return

• Document any damage for insurance

• Call a professional for assessment and repairs
