Questions About Asphalt or Concrete? Start Here.
Whether you’re planning a new driveway, managing a parking lot, or looking to extend the life of an existing surface, this page answers the most frequently asked questions we receive from residential and commercial clients across Alaska.
Residential FAQs
Asphalt Driveways
What is asphalt paving?
Asphalt paving is the installation of a durable surface made from aggregates and asphalt binder, commonly used for driveways, roads, and parking areas.
How long does a new asphalt driveway last?
With proper installation and maintenance, asphalt driveways typically last 15–25 years. Climate, drainage, and traffic conditions all affect lifespan.
How soon can I drive on new asphalt?
You should avoid driving or parking on new asphalt for 3–5 days.
Avoid extended or repeated parking for the first 14 days, and avoid parking during the hottest part of the day for the first year, as asphalt remains pliable during warm weather.
Also avoid:
- Sharp or stationary power steering turns
- Trailer jacks, kickstands, or similar pressure points unless placed on a board or pad
Do I need to sealcoat my driveway?
Yes. Sealcoating protects asphalt from moisture, UV exposure, oil, and chemicals. Most residential asphalt should be sealcoated every 2–3 years once the asphalt has fully cured (typically after the first year).
Why does asphalt crack?
Cracking occurs due to Alaska’s freeze–thaw cycles, moisture intrusion, heavy loading, and natural aging. Early crack sealing helps prevent larger issues and structural damage.
Concrete Driveways & Sidewalks
How long does concrete last?
Properly installed and maintained concrete can last 15–30 years or more, depending on soil conditions, weather exposure, and maintenance
How thick should a concrete driveway or sidewalk be?
Sidewalks are typically 4 inches thick.
Residential driveways are generally 4–5 inches thick, with thicker sections recommended for heavier vehicles or RVs
Will my concrete crack?
Yes. All concrete develops cracks over time due to shrinkage and movement. Proper installation, reinforcement, and control joints help manage where cracks occur.
When can I walk or drive on new concrete?
Concrete requires more curing time than asphalt.
- Foot traffic: Wait 3 days
- Passenger vehicles: Wait 14 days
Additionally, avoid paving asphalt directly next to new concrete for 3–7 days to protect edges from heat transfer.
Is sealing concrete necessary?
Yes. Sealing protects concrete from moisture, staining, and freeze–thaw damage. SLS recommends sealing once a year for standard concrete and twice a year for decorative or stamped concrete.
Avoid all de-icing chemicals during the first year, as they can cause scaling and surface damage.
Commercial & Property Owner FAQs
Commercial Parking Zones
Why is crack sealing important?
Crack sealing prevents water from entering the pavement base, reduces freeze–thaw damage, and extends pavement lifespan.
How often should a parking lot be sealcoated?
Most parking lots benefit from sealcoating every 2–3 years, depending on traffic volume and weather exposure.
Can work be completed without shutting down operations?
Yes. Commercial projects can be completed in phases or during off-hours to minimize disruption to customers and employees.
Does sealcoating fix cracks or potholes?
No. Sealcoating is a protective top layer. Cracks and potholes must be repaired before sealcoating for best results.
Do you provide ADA-compliant striping?
Yes. We provide ADA-compliant layouts, including accessible parking stalls, van-accessible markings, and required crosshatching.
Is repair better than replacement?
Often, yes. If the pavement base is still sound, crack sealing, patching, or overlays can extend the surface’s life. Replacement is recommended when base failure or severe deterioration is present.

How to Protect Your Surface
Proper care after installation plays a major role in how long your asphalt or concrete lasts. These guidelines help protect your surface from Alaska’s weather and seasonal conditions.
Asphalt
- Avoid driving/parking for 3–5 days
- Avoid extended or repeated parking for 14 days
- Avoid sharp turns or stationary steering
- Use boards/pads under kickstands, trailer jacks, and similar pressure points
Concrete
- Avoid foot traffic for 3 days
- Avoid vehicle traffic for 14 days
- Avoid paving asphalt directly next to concrete for 3–7 days
- Do not use de-icing chemicals on new concrete
