True North Asphalt has two processes for filling cracks. Both can be used effectively to prevent cracks from spreading and adding longevity to your paved surface. Each process will be thoroughly explained during your initial job walk-through to decide which option best fits your needs and budget.
- Over-banding: This process begins by using high pressure air to remove all the vegetation and loose debris from existing cracks. The crack is then filled with a DOT approved hot rubber crack fill using the banding method. This process not only fills the existing crack but creates an overlay to prevent that crack from opening during a freeze/thaw cycle.
- Routing: Routing begins by using a routing machine to cut a ½” groove along the existing crack. This gives the hot rubber more surface to adhere to, extending the life of the repair. After routing, the process follows the same steps as over-banding: high pressure air cleaning and then filling with hot rubber using the banding method.
When to Seek a Professional
- A simple crack is relatively easy to correct and occurs naturally as the ground moves and as asphalt ages.
- A straight line or diagonal crack can be easily filled.
- Settling cracks usually start to appear within 1-4 years after new asphalt is installed. If your pavement falls in that timeline, you may need to start a preventive maintenance program. For a no-commitment free consultation, contact us today.
