Sealcoating

Our top quality sealcoating is a specially formulated layer of liquid that protects your asphalt overlay from water damage, UV rays from the sun, heavy precipitation, and various forms of vehicular harm. Sealcoating can extend the lifespan of your plot of pavement by about 10 to 20 years.

Asphalt Crack Filling

The “Crack Fill” technique involves removing damaged asphalt and debris, cleaning out the area, then filling the area with Thermoflex hot tar. Thermoflex is a premium, single component, hot applied, asphalt/rubber joint and crack sealant.

Parking Lot Sign Installation

Our team can not only paint your handicap parking spots, but we can install your handicap parking signs, no parking signs, and drive-thru signs as well to keep your parking lot well labeled and easy to navigate.


We also do bollard installations. Bollards are primarily a visual guide, but they also guide traffic and mark boundaries. They may be a helpful addition to your parking lot.

Parking Lot Striping

Parking Lot Striping, or Pavement Marking, is essential for the safety of cars and pedestrians, as well as the overall aesthetic and curb appeal of your business property. It’s suggested that property owners complete parking lot re-striping in Tennessee every 2-3 years, depending on the amount of traffic in your parking lot.

Full Depth Asphalt Repair

Full-depth patching (FDP) is repairing potholes or other damaged areas of pavement by removing the entire depth of asphalt and replacing it with new, fresh asphalt. This type of patching is usually done on driveways, parking lots, and other high-traffic areas where potholes are more likely to form.

Asphalt Cleaning
& Maintenance

While cleaning your parking lot before seal coating is included in our seal coating service, we also offer parking lot cleaning services if you need a cost-effective way to freshen up your parking lot before it’s time for your next seal coating.

Regular pavement maintenance is money well spent protecting your parking lot. Not only are cracked, worn pavement and potholes aesthetically displeasing, but they also pose a safety hazard for drivers and pedestrians.

Driveway Sealcoating

Cracks in your driveway? We can repair damage done to your asphalt driveway by weeds, oils, water, weather, wear & tear. Seal coating increases your home’s curb appeal and get it looking as good as new. Sealcoating can also help extend the life of your driveway and require less maintenance in the long run.

Infared Asphalt Repair

Infrared asphalt repair is the process through which existing, compromised asphalt is heated and replenished before being mixed with new asphalt and compacted. It outlasts all other methods as no seams or joints are created.

Speed Bumps Painting & Installation

Make sure your parking lot curbs and speed bumps are clearly visible for pedestrian and vehicle safety around your business with a paint re-fresh every 2-3 years, depending on traffic and wear and tear in your parking lot.

You can count on us to install asphalt speed bumps or speed humps. Speed bumps and humps are an effective way to slow down traffic, especially in residential areas and parking lots, increasing safety.
