Crack sealing and crack filling are two common maintenance methods for asphalt surfaces, but they serve different purposes. Crack sealing involves using a flexible, rubberized sealant designed to expand and contract with pavement movement, making it ideal for active cracks. Crack filling, on the other hand, uses a more rigid material that works best on non-working cracks. Choosing the correct method can extend the life of your pavement and reduce costly repairs down the road. Professionals use high-quality asphalt crack filler machines and crack seal machines for efficient and long-lasting results.
