Seal Coating & Crack Filling

Cracks in pavement should be filled annually to extend your pavement life. Crack filling involves pouring hot melted rubber in to the crack in the pavement. When the rubber cools, the pavement’s integrity is recovered. Seal coating is the application of a specially formulated sealer specifically engineered to protect the asphalt surface from harmful UV radiation and harsh chemicals.

First, we come in and edge your driveway/parking lot. We use a weed trimmer to remove the grass from the pavement cracks. Next, we clean the surface area and fill the cracks with a hot melted rubber crack sealer. We then seal our way out of your property and set up caution tape to block any entrances, so the sealer has a chance to dry completely prior to being driven on. To maintain your property’s cleanliness, we hand brush sealer along sidewalks and areas next to any buildings. This prevents sealer from “splashing” up on your building(s).


Q: What product do you use?

A: Our sealer, “Triton Supreme”, is a steam cracked resin sealer.  This is as close to a coal tar sealer as you can get.  Through years of experience we have found this to be the best sealer for driveways and parking lots for our climate.

Q: When is the best time to seal my new driveway or parking lot?

A: As soon as it cures.  Keeping your driveway crack filled and seal coated will allow you to enjoy it for many years.

Q: Does your sealer go on hot?

A: No, all sealers are now cold applied.  The Minnesota Pollution Control Agency (MPCA) has stopped all hot applied and coal tar sealer use within the last 10 years.

Q: When can we drive on it?

A: After 48 hours, longer, if possible.  The first week requires caution to not mar the sealer with vehicle tires.  During this time it is important not to turn your wheels while at a complete stop.

Q: When can we walk on the driveway (pets included)?

A: Sealer takes approximately 48 hours to dry.  We recommend minimal to no traffic of any kind during the first 48 hours.  When the sealer is dry it will turn from a wet, shiny look to a dry, matte look.

Q: Will this hurt my pet’s feet?

A: No.  It is important to note that it can turn their paws black which can be tracked into your home.  It is best to wait until the sealer is dry before pets are allowed on it.

Q: How long will this sealer last?

A: The average sealer lasts 2 to 3 years.  The less traffic on driveway, the longer it will last. Regular maintenance (sealing and crack sealing) can double a product’s life.

Q: What can I expect after my driveway/parking lot is sealed?

A: With the initial sealcoating your surface will have a shiny, wet look.  Within a week you will notice the color change to a flat, matte black with a slight blue tint.  This is temporary and a part of the curing process.  After approximately 1 month it will lose the blue tint and be a solid black color.
