3 Reasons You Should Have Your Driveway Sealcoated

As a homeowner, it isn't always easy to know what to do or who to call to care for elements of your home and yard. Although you probably understand the importance of having those trees trimmed by professional pruners, you might not have any clue what to do for that asphalt driveway. Here are three reasons that you should have your driveway professionally sealcoated, and how it can help you in the long run.  

1: Sealcoating Waterproofs the Surface

Have you ever thought about how many different liquids and chemicals your driveway encounters on a daily basis? In addition to water and snow, that pavement might also be forced to deal with oil, gas, ice melt, and anything else that gets dropped onto the surface. Unfortunately, as asphalt ages, the binding agent that holds the aggregates together deteriorates, creating an easy pathway for liquids to penetrate the surface and cause deep-set stains. 

However, you might be able to improve the water and chemical resistance of your driveway by getting the area sealcoated. Sealcoating is a liquid protective barrier that contains bitumen, emulsified asphalt, and mineral fillers. Asphalt contractors can spread sealcoating evenly over the original pavement, filling in tiny voids and protecting the area from liquid.

Because recently sealcoated pavement is smoother than older surfaces, it is easier to keep clean. Instead of dirt, grass clippings, and ice melt collecting in fine crevices, those substances can be swept away easily.

2: Sealcoating Prevents Asphalt Damage

Unfortunately, stains aren't the only threat that liquid can pose to your driveway. During the cold season, rain and melted snow can leak into your pavement, freeze, and cause serious asphalt damage. If you don't protect your driveway by having it sealcoated, you might eventually have to deal with these types of issues.

  • Cracks: How do you feel about dealing with thousands of cracks spread across your entire driveway? In addition to compromising the structural integrity of your asphalt, cracks can also give weeds an easy place to grow, which can make your property look terrible.
  • Potholes: As water continually attacks cracked asphalt and freezes overnight, it can break away large chunks of asphalt, creating dangerous potholes. 
  • Grade Depressions: After pavement has been compromised by water, cracking, and potholes, large areas can start to fail and create grade depressions. When this type of damage forms, sections of asphalt can sink further into the ground, creating an uneven appearance and driving surface.

However, because sealcoating provides a barrier between your driveway and the elements, it can dramatically extend the life of your pavement. In fact, regular asphalt sealcoating can make your driveway last as long as 30 years. Some experts recommend getting your asphalt sealed every 3 years, or whenever it starts to look dry and brittle.

3: Sealcoating Revitalizes Driveway Aesthetics

Have you ever wondered why some asphalt surfaces look rich and black, while others look old and gray? Over time, harsh UV rays and water can cause the surface of your asphalt to oxidize and turn ashy. However, a fresh layer of sealcoating can restore the original dark brilliance to the space, so that your driveway looks brand new.

Believe it or not, sealcoating also makes the surface of your pavement more pliable, so that it is more likely to endure the weight of traffic. Because sealcoating darkens the space, it will attract more sunlight and heat up the tar emulsion, making the entire area more flexible. When the surface has a little extra give and take, it is less susceptible to breaking under the weight of passing cars, which can protect your driveway from ugly damage.

Sealcoating your driveway will save you from dealing with asphalt trouble later on, while keeping your curb appeal intact.
