Fixing The Cracks In Your Asphalt Driveway

by Minnie Larson

The asphalt driveway that you park on each day needs your attention. Asphalt is not a surface you can install and forget about—it needs care. If you have cracks forming on your asphalt driveway, it's important that you take action before the cracks cause even more damage. Here, you'll learn how to prepare and repair the asphalt cracks to prevent further damage.

Preparation for Sealing

The most critical step in fixing those cracks is the preparation of the cracks. If you don't prepare the cracks properly, the seal that you put down later will not fix the problem.

Start by sweeping the entire surface—you can do this with a push broom, or you can use a wet-dry vacuum to suck up all of the debris. The more dirt and debris that you can get out of the crack, the better the new seal will do its job.

Professional asphalt contractors don't stop there—they use an air compressor and wand to blow the dirt out of the cracks. This not only blasts the dirt out of the crack but can help with drying any moisture in the crack to create the best possible bond between the sealant and the asphalt.

Note: If you choose to use an air compressor and wand to blow the dirt out of the cracks, make sure to check the compressor from time to time to make sure that it's not blowing damp air into the crack. If your compressor isn't equipped with oil and moisture filters, you could be introducing more moisture to the crack and will have to wait longer to make the repair.

Choose the Sealant

Now that you've prepped the crack, you need to choose the sealant to get the job done right. There are three families of sealant:

  • Cold-applied
  • Hot-applied
  • Chemically cured

The most commonly used and most effective is the hot-applied sealant. This is because the hot sealant will bond to the asphalt well and seal the crack fully. Cold-applied sealant is nice for fast, small repairs, but if you're looking for a long-term fix for your cracked asphalt, you'd do best to opt for hot-applied sealant.

Talk with an asphalt repair specialist at a company like Sealtech Asphalt Inc. for assistance with making repairs to your asphalt driveway. The sooner you act, the less damage that you'll have to repair. Allowing water to continue to flow into the crack will result in water flowing under the asphalt and causing extensive damage that is much more work to repair.
