Durable Asphalt Repairs – The Importance of Routing Before Sealing Cracks

Years of exposure to rain, snow, humidity, and vehicle traffic can wear down asphalt driveways and cause them to crack. Cracks allow water to seep into the asphalt, which could lead to water damage, extensive cracking, and weakening of the asphalt foundation. Usually, the first instinct in such a case would be to undertake concrete sealing and remedy the situation. However, did you know that crack routing can improve the performance of your asphalt driveway repairs and prolong their life? Read on to find out more about crack routing, how it's carried out, and ways it can help in improving asphalt crack repairs.

What is crack routing?

Crack routing is an asphalt repair procedure that's usually carried out before crack sealing to ensure sufficient coverage of the sealer in the crack and improve its performance. In this technique, a routing machine is used to open up the crack further and widen it. Any equipment that can open up the crack without causing extensive damage to the driveway can also be used. Once it has been widened, the sealant is used to seal it and restore the appearance of the surface.

Why route before sealing?

To many people, it beats logic to expand a crack in your driveway just to seal it up again. However, this technique can help not only in strengthening your repairs, but also in improving the performance of the entire area around the crack. In most cases, when asphalt driveways crack, the crack occurs in a crooked line down the asphalt. Applying a sealant to such a crack will mean that there will be spaces that won't be properly filled, and this could further degrade the driveway. By opening up the crack, you create an even channel on which you can apply the sealant. This will ensure that the entire crack is evenly covered on both sides.

Also, asphalt driveways are bound to expand and contract due to temperature changes. Any spaces that weren't filled correctly during the repairs can begin to open up during expansion and contraction. You may end up dealing with more cracks on your driveway as a result. By routing, you ensure that all the spaces are filled, and this curbs further damage to the driveway.

Should you undertake DIY routing?

DIY crack routine on asphalt driveways may not be recommended unless you have the necessary tools and expertise. You may try to expand the crack and cause further damage to your driveway. Utilizing the services of a professional will ensure that you get quality and durable repairs. The contractor will also recommend the best sealant to use from the numerous brands in the market.
