Preventing Damage: How Sealcoating Shields Your Driveway from the Elements

Goodly Service • Aug 30, 2023

If you've invested in an asphalt driveway, you'll know the aesthetic appeal and value it adds to your property. Like most homeowners, you want to maintain its sleek, dark appearance and structural integrity for as long as possible. However, external elements are continuously conspiring to degrade and damage this asset. Enter sealcoating, a protective barrier designed to fend off the assault from nature and man-made hazards. This article dives deep into how sealcoating works to shield your driveway from damage and why it's an essential maintenance step for every asphalt driveway owner.

1. What is Sealcoating?

Before we explore the protective features of sealcoating, it's crucial to understand what it is. Sealcoating is a protective layer, typically made from coal tar, asphalt cement, or acrylics, that's applied over an asphalt surface. It acts as a barrier against various damaging factors, helping prolong the life of your driveway.

2. Fighting Off the Sun's Harmful UV Rays

Much like how our skin is susceptible to the harmful effects of UV rays, so too is our asphalt driveway. Prolonged exposure to sunlight oxidizes the surface of the driveway, causing it to fade and become brittle. This brittleness leads to cracks and an overall weakened driveway structure. Sealcoating acts as sunscreen for your driveway, reflecting UV rays and preventing oxidation.

3. Shielding Against Water Damage

Water might seem harmless when we drink it or use it for daily tasks, but when it comes to the longevity and health of your asphalt driveway, it can be a formidable adversary. The insidious nature of water damage often means problems are well-advanced by the time they become noticeable. Sealcoating serves as the first line of defense against this silent menace. Here's a deeper dive into how sealcoating shields driveways from water-induced harm:


  • Prevention of Water Penetration: Asphalt, by its nature, is porous. This means it has tiny spaces or voids that can absorb water. Over time, the continuous cycle of water infiltration followed by evaporation can compromise the driveway's structural integrity. Sealcoating fills and seals these pores, creating a waterproof barrier on the surface, preventing moisture from seeping deep into the layers of asphalt.

  • Guarding Against Freeze-Thaw Cycles: In colder climates, the freeze-thaw cycle can wreak havoc on driveways. Water that enters the tiny cracks of a driveway can freeze during colder temperatures. As water turns into ice, it expands, exerting pressure and widening the cracks. When it thaws, the water seeps deeper, only to freeze and expand again in the next cold spell. Sealcoating effectively blocks the water from entering these cracks in the first place, preventing the destructive effects of this cycle.

  • Reduced Surface Erosion: Continuous water runoff, especially during heavy rains, can erode the surface of an untreated driveway. This erosion can lead to the formation of ruts, depressions, and overall surface degradation. The smooth and water-repellent surface of a sealcoated driveway ensures efficient water runoff, reducing the erosive effects of flowing water.

  • Protection Against Spalling: Spalling refers to the flaking or chipping of the surface, often caused by the ingress of water. It's a sign that the water has affected the binding agents within the asphalt, causing it to lose its cohesion. By creating an impermeable layer, sealcoating prevents the water from reaching and interacting with these binding agents, thus averting spalling.

  • Preventing Foundation Erosion: Water that's not efficiently channeled off a driveway can pool around the edges and start to erode the foundation. This not only affects the driveway but also the surrounding landscape. The waterproof nature of sealcoated driveways ensures better water management, directing it away from the foundation and safeguarding the structural base of the driveway.


The presence of water might seem inconsequential, but its cumulative effects can lead to substantial damages and
costly repairs. Sealcoating, with its water-repelling properties, is an invaluable tool in maintaining the beauty, functionality, and longevity of your driveway. It acts as an umbrella, ensuring your driveway remains unscathed regardless of the seasonal showers or winter snow melts it endures.

4. Resisting Oil and Chemical Spills

Cars can, unintentionally, be enemies of driveways. Oil spills, gasoline, and other vehicle-related chemicals can break down the binding agents in asphalt. When sealcoating is applied, it creates a barrier that prevents these harmful chemicals from penetrating the asphalt, ensuring the driveway remains intact and stain-free.

5. Enhancing Aesthetic Appeal

Apart from the protective features, sealcoating rejuvenates the rich, dark color of a new asphalt driveway. This not only boosts curb appeal but also makes line markings more visible in cases of shared driveways or parking lots.

6. Cost Savings in the Long Run

While sealcoating might seem like an added expense, it's a preventive measure that can save you money in the long run. By shielding your driveway from potential damage, you extend its lifespan and delay costly repairs or replacements. Over the years, this can amount to significant savings.

7. Easier Cleaning and Maintenance

Sealcoating your driveway is like applying a fresh, protective topcoat on a wooden table. The smooth, non-porous layer it creates not only offers protection but also makes cleaning a significantly easier task. Here's how sealcoating simplifies the cleaning and maintenance process:


  • Smooth Surface for Sweeping: Over time, an unsealed driveway can become rough and uneven due to wear and erosion. Sealcoating smooths out these imperfections, making it easier to sweep away leaves, dirt, and other debris. No more getting your broom caught in tiny crevices or struggling with stubborn patches of dirt that cling to rough spots.

  • Stain Resistance: Spills are inevitable. Whether it's oil from a parked car, a dropped drink, or any other fluid, they can often leave unsightly stains on an untreated driveway. The sealcoat acts as a barrier, preventing these substances from seeping deep into the asphalt. This makes it much simpler to wash away spills before they can set and become permanent stains.

  • Reduced Weed and Moss Growth: The small cracks and crevices in an untreated driveway can be breeding grounds for weeds and moss. Sealcoating fills these spaces, preventing plants from taking root. This means less time spent on weeding and more time enjoying a pristine driveway.

  • Improved Water Runoff: One of the key attributes of a well-sealed driveway is its ability to effectively repel water. Instead of water pooling or seeping into the substrate, it rolls off the smooth sealcoated surface. This not only reduces water damage but also makes it easier to wash the driveway, as the water carries away dirt and debris.

  • Resistance to Color Fading: Asphalt, when exposed to the sun and elements, can gradually lose its deep black hue and start to appear gray and faded. A sealcoated driveway retains its rich color for longer, reducing the need for frequent reapplications or other treatments to maintain its appearance.

  • Enhanced Durability Against Wear and Tear: Daily activities, such as driving, parking, or even kids playing, contribute to the wear and tear of the driveway surface. A sealcoated driveway is better equipped to handle this daily traffic, ensuring less frequent touch-ups and repairs.


Sealcoating not only prolongs the life of your driveway but also cuts down on the time, effort, and money spent on cleaning and maintenance. It's a win-win for homeowners seeking both functionality and aesthetics.

8. Protecting Against Temperature Variations

Asphalt driveways are subjected to the whims of changing weather patterns, and this means dealing with varying temperature ranges. These temperature shifts can be drastic, leading from blazing hot summers to frigid winters.


Every time the temperature rises, asphalt can expand. Conversely, it contracts when temperatures drop. This continuous cycle of expansion and contraction causes the material to lose its flexibility over time, leading to surface cracks. These cracks can develop into potholes if left unattended.


Sealcoating aids in this situation by providing a flexible protective layer that can adjust with these temperature variations. This adaptability prevents the asphalt underneath from direct exposure to temperature changes, thereby reducing the risk of cracking. Moreover, sealcoated driveways have an enhanced ability to repel water, which is crucial during freeze-thaw cycles in colder climates. Water that enters cracks can freeze, and as it expands, exacerbates the cracks. By preventing water infiltration, sealcoating indirectly reduces the damage caused by these freeze-thaw cycles.

9. Reducing Surface Wear from Traffic

Every time a vehicle moves over the asphalt, it applies pressure and causes friction. Over time, this constant wear and tear can degrade the surface, leading to ruts, depressions, or even the aggregate in the asphalt becoming exposed. Sealcoating offers an additional layer of protection, distributing the weight and pressure of vehicles more evenly and preventing premature wear. This layer is also resistant to the abrasive effects of traffic, ensuring that the driveway remains smooth and intact for longer.

10. Improving Resistance to Plant Growth

In some cases, especially if there are tiny cracks or gaps in the asphalt, weeds or grass might begin to grow through the driveway. Not only does this affect the appearance of your driveway, but the roots of these plants can also cause further damage by pushing the asphalt apart. Sealcoating fills these small cracks and pores, denying plants a place to take root and ensuring your driveway remains pristine and free from unwanted green guests..

Conclusion
