Driveway and Parking Lot Asphalt Repair and renewal:

Asphalt Patching and Repair

Asphalt patching is for jobs that are bigger than a few potholes. To perform an asphalt repair that will hold in our northern climate it sometimes involves removing large parts of damaged asphalt paving. The base material may also be removed if it is inadequate. An asphalt bonding agent is sprayed to help the new asphalt stick to the orginal surface. The new asphalt is packed higher than the existing surface and then compacted to become leveled. All projects are different, so please give us a call for a no obligation estimate.HERE is a 2013 project in Superior of a parking lot that had a tough middle area but the rest of the lot was solid. This can save a lot of money for businesses and homeowners.

Blacktop, Overlays & Concrete Repair

Ideally, we like to help our clients maintain their asphalt and concrete investments in the first place. At times a parking lot or driveway are beyond repair and we will tell you. Then the job requires blacktopping or an overlay which means scraping off part of the existing surface and applying a new layer of pavement. We also apply the same care and professionalism to our concrete projects. Blacktop or concrete repair- one thing you can count on is A-1 Asphalt to give you a honest service at an honest price. A-1 will gladly provide free consultation options on the condition and potential solutions for your parking lot or driveway problems.

Asphalt Crack Sealing

Northern Wisconsin and Northern Minnesota Winters demand asphalt cracks need to be filled. We first clean the surface area with compressed air or routed to create a reservoir for more filling. Hot liquid asphalt is applied to fill in the cracks and to allow space for extraction and compression during weather changes. Cold tar patching is also available. Next to regular sealcoating, staying on top of those cracks is the most important way to maintain your asphalt. Letting a crack go until next year is a recipe for disaster. Please give us a call, you be pleasantly surprised how affordable and effective crack filling can be with A-1.

Pothole Repair

Twin Port's area potholes occur when moisture penetrates cracks in the asphalt surface of a road or driveway. Cold weather freezes the water and causes it to expand. A pothole forms when dirt and gravel is forced out leaving a hole. The ice eventually melts and the stressed asphalt becomes a pothole. Our driveway and parking lot maintenance programs can help reduce the likelihood of pothole formation in the first place. To avoid potholes in the spring, call us now for an estimate on how best to maintain your asphalt and avoid potholes in the first place.We clear out all of the debris from the affected area before applying any asphalt. We fill the hole with hot liquid asphalt to make use the mixture fills every craves to prevent moisture sipping in. Then we tamp down the mixture to create a solid and tight seal. Finally we allow 1-2 days for the asphalt to harden. Ideally it's best to stay off the patch for as long as time as possible. 20 years of pothole repair and asphalt patching will be working on your patch and making sure the job is done right
