Experts in cost-effective asphalt sealing
Sealcoating asphalt allows pavement to stay flexible for as long as possible by protecting the binder (liquid asphalt) that holds the pavement together. Unfortunately, many sealcoating methods don’t get the job done, or simply look bad.
Over the past 25 years, we’ve worked to find innovative ways to make and apply an asphalt sealcoat that works.
And the results are in: we are the first asphalt sealing company in Northern California to perfect our own spray-on sealcoat machines. This method is the only way to get a uniform appearance and coverage on tight surfaces (which we find on 90% of the lots we seal).
At DRYCO, we’d love to put our innovation to work and be your asphalt sealcoating contractor. We guarantee competitive pricing and offer large sealcoating crews and equipment who can handle large jobs over weekends and holidays resulting in the least amount of disruption to your business.

Sealing Surface Preparation
Preparation is the most critical step of the sealcoating process and is most often the indicator of a poor job. The surface must be perfectly clean and all cracks 1/4″ and larger need to be blown out and filled with a high-quality, hot-applied crack filler such as Craftco or Duraseal. DRYCO sealcoating solutions always include hot-applied crack filling to ensure that the finished product meets our standard of quality. Also, any striping changes need to be covered with black paint so they don’t show through—a phenomenon known as ghosting—as the sealcoat wears off.

Sealcoat Spray-on Application
Most surfaces have been sealcoated more than once in their lifetime. This creates a “tight surface” where all the voids have been filled and the sealer has worn off the rocks, giving the surface a worn-out appearance. The squeegee method of applying sealcoat pulls the sealer off the tight surface and creates streak marks, so DRYCO re-engineered our machines to spray the material instead. You get more sealer on the ground spraying than you do when you squeegee, and this equates to greater value for our customers and a seamless appearance.

Like-new Finished Product
After the job is complete, your pavement will regain a smooth, deep-black surface. We meticulously hand trim the edges of your pavement surface to maintain a clean separation from your concrete borders. And we are so confident in the quality of our work that we offer our “best in the business” three-year warranty on all of our sealcoat applications. We always do things the right way the first time, and the result is quality you can count on.
Pavement Maintenance
If you set up a proper pavement maintenance plan and act proactively to protect your investment by regularly sealcoating on schedule, the life of your parking lots and game courts will be extended significantly—and therefore your costs minimized over the life of the hardscape.
