Sealcoating is the most effective way to protect and preserve your asphalt. A new driveway or parking lot should be sealed within the first year after paving, then every 3–5 years to maintain full protection and appearance.


What does Sealcoating do?

  • Forms a protective barrier that shields asphalt from water, ice, chemicals, and UV rays 
  • Helps prevent surface wear and premature aging 
  • Restores a deep, jet-black finish that boosts curb appeal 
  • Keeps asphalt flexible and healthy so it lasts longer and performs better
  • Helps prevent rock and sand separating


Why Our Sealcoat is the Best

  • We use water-based coal tar emulsion, the industry’s most durable and proven asphalt sealer 
  • Coal tar is naturally resistant to oil, gasoline, and automotive fluids, keeping your asphalt from softening or breaking down 
  • Higher solids content creates a thicker, longer-lasting protective layer than oil-based sealers 
  • Fast-drying additives help the coating cure evenly for a smooth, uniform finish
  • Fine silica sand is blended in to improve traction, strengthen the coating, and give your driveway or parking lot a richer, more professional texture

What Causes Deterioration?

Asphalt naturally breaks down over time, but several everyday factors speed up the process and cause the surface to weaken:

  • Oxidation: From the moment asphalt is installed, the sun begins drying out the binder (the “glue” that holds everything together). As it oxidizes, the pavement turns from black to gray, which turns into a dried out state.
  • Weather Exposure: Heat, freezing temps, rain, and snow all stress the pavement. Freeze-thaw cycles push water into small cracks, then expand them as temps drop.
  • Oil, Gas, and Chemical Spills: These liquids soften and dissolve the asphalt binder, creating soft spots, potholes, and premature failure.
  • Traffic Wear: Daily vehicle weight and turning motions grind down the surface, especially in high-use areas.
  • Lack of Routine Maintenance: When cracks aren’t sealed and the surface isn’t protected, water and UV rays break the pavement down much faster.
