We provide sealcoating and pavement repair services primarily in the Northfield area, but we also service much of Rice, Dakota and Scott counties.

Regular maintenance is key to extending the lifespan of your asphalt. Our maintenance services include crack sealing, pothole repair and sealcoating to ensure that your pavement stays in top condition year-round.

Sealcoating is a part of regular asphalt maintenance that should be applied every 2-3 years depending on weather and other conditions. The application of sealant protects the asphalt from oils, weathering and water damage.

Crack filling or crack sealing is done to prevent water from entering the asphalt and damaging it as it freezes in the winter months or to prevent the water from deteriorating the sub-base(foundation). Typically a hot rubberized sealant is used to seal the cracks. This can be done by itself or in conjunction with sealcoating.

"Alligator Cracks" are a series of cracks that form which looks like alligator skin. A special filler/sealant is used for these types of cracks. This repair is done for the same purpose as crack filling, to prevent water penetration which causes more damage over time.

Pothole repair fixes holes in asphalt by applying a cold patch, hot patch or Infra-Red application.  Pothole repair is necessary to prevent further erosion of the asphalt, prevent damage to vehicles or injuries to pedestrians. Blackwolf Asphalt currently offers cold patch repair and infrared patching.
