Living in the Southwest, we have to protect ourselves from the heat of the sun with sunscreen to avoid skin damage – and pavement is no different. Constant exposure to the sun’s harsh ultraviolet rays, daily traffic levels, and moisture in combination with the normal aging process causes the oils in your new pavement to start drying out, or oxidizing. This in turn causes fading and cracking, and you’ll notice small stones breaking away. So, what’s the best way to combat this process? Sunscreen for your skin, and a sealcoat for your asphalt.

That’s where D&O comes in. Prior to sealcoating, our experienced crews will repair any necessary pavement imperfections and seal cracks, in addition to sweeping away debris to ensure a clean surface. Next, we carefully apply the sealcoat material, using squeegees and shields to protect curbs and sidewalks. Finally, we will restripe back to the original layout, giving you the smooth, black appearance of a new parking lot for the fraction of the price.

By sealcoating your pavement, we will help you:
  • Create an aesthetically pleasing look
  • Prevent oxidation
  • Protect against spill damage
  • Weatherproof the surface
  • Reduce maintenance by shielding the pavement against the elements
  • Preserve your investment by making your property safer, cleaner, more attractive, and longer lasting
Take the steps to protect your investment from the elements – talk to us about developing a long-term maintenance plan that prevents future damage. Call us at 623-463-0555 or
