Cracks in the pavement allow water and debris to accumulate and cause damage. If you’ve noticed cracks forming in your blacktop driveway, you’re likely searching for ways to fix them. The differences between crack sealing and crack filling are worth understanding to choose the best solution.
While both crack sealing and crack filling address driveway cracks, their purposes vary. Crack filling focuses on repairing the damage by filling in cracks to prevent immediate growth.
On the other hand, crack sealing is a more advanced method to provide all-weather protection by sealing cracks and keeping moisture out permanently. Crack sealing is more effective than crack filling for crevices that expand and contract with temperature fluctuations. Crack filling works better for small cracks.
Another key difference between crack sealing and crack filling is the materials used. Crack filling uses asphalt-based materials that bond quickly to the edges of the crack. They are ideal for short-term fixes and non-dynamic areas of a driveway.
Crack sealing uses specialized rubberized sealants that remain flexible, so they can handle expansion and contraction. The superior quality of sealing materials makes it more durable under varying conditions.
Crack sealing involves heating a rubberized sealant until it melts and applying it directly to the cracks. The material will fully bond with the asphalt surface, creating a watertight seal. In contrast, crack filling uses a simpler approach. You apply the filler manually, and it settles into the cracks without heating. This allows for faster application but reduces durability when used on expanding and contracting cracks.
Crack filling is budget-friendly and offers a straightforward solution for minor imperfections in the pavement. Crack sealing is more expensive, but it delivers better protection over time and can save you from costly repairs in the future. Deciding between the two depends on whether you seek a short-term fix or a long-term investment.
Crack filling provides a temporary solution and may need reapplication within a year or two. Crack sealing, by contrast, can last many years due to its high-quality materials and water-resistant properties. Crack sealing outperforms filling, making it the more economical choice in the long run.
