Crack Sealing FAQ 1. Q: What are the primary benefits of sealing cracks? A: The primary benefit of sealing cracks is the reduction of cost in future asphalt repairs, as well as increasing the longevity of your existing asphalt pavement. 2. Q: Can all cracks be sealed? A: No, not all cracks can be sealed. When pavement starts to become alligatored, sealing the cracks is no longer a useful repair method. This type of damage is beyond the ability to repair. 3. Q: When should asphalt pavement be crack sealed? A: As soon as cracks are noticed and larger than 3 mm in width they should be sealed.As far as time of the year goes, cracks should be sealed before the rainy weather hits. The idea is to keep water from penetrating into your sub grade layer of your asphalt. 4. Q: Are cracks of all sizes able to be sealed? A: No,not all cracks, but most cracks under 3 cm can be sealed. Cracks under 3 mm can also be ignored, as regular sealcoating material will typically fill these small cracks in. 5. Q: How do I repair cracks over 3 cm in width? A: Cracks over 3 cm in width should be repaired using hot mix material instead of crack sealing materials. What is the optimal temperatures to apply crack seal? The optimal temperatures to apply crack seal are above 7 degree centigrade. 6. Q: How is crack sealing applied? A: Crack sealer material is pre-melted in a large pot called a kettle, and then pumped to a wand with a banding pot at the end. The liquid material fills the small receptacle and creates a 2 - 5 cm band over the crack as it is pulled. 7. Q: What affects the price of crack sealing? A: Factors that can add to the cost of sealing include the overall condition of the pavement. The proximity of your cracks, the amount of preparation work required to apply the sealer, and the width and depth of cracks. 8. Q: How much crack sealing can you do in a day? A: By use ESUN crack sealing machines, most of our customers can install between 2,000 and 6,000 linear meters per day. 9. Q: How soon can I drive on a freshly sealed crack in a asphalt pavement? A: It is recommended to give crack seal material as much time as possible to dry.There are some techniques that can be employed to allow this to happen faster. 10. Q: Will the crack sealer material track into my buildings? A: The answer is yes. Freshly poured crack seal can be tracked into buildings, cars,sidewalks etc. The best way to avoid this is to have crack sealer applied on days when traffic is reduced as much as possible. If this is not possible another solution is to apply sand over freshly poured crack sealer material to greatly reduce the chances of it tracking. 11. Q: Can crack seal be done on the same day as seal coating? A: The longer amount of time you can give between sealing your cracks and applying sealcoating the better. At a minimum we like to see at least 72 Hours between these applications. Crack sealing can be done on the same day,however it will not do as well as the crack sealer that was given the proper amount of time to dry. 12. Q: What is crack routing? A: Crack routing is the act of machine routing cracks to a uniform width and depth before sealant is poured into the cracks. Routing machines cut a 1.5 x 2 cm channel into the crack of the pavement. It is cleaned then sealed. These cuts allow a more uniform application of sealer however they are not always recommended. 13. Q: What if cracks have moisture in them? A: Cracks generally do store moisture and for that reason we use a heat lance to dry those cracks ahead of application to allow proper adhesion of the rubberized materials. 14. Q: Do cracks get completely sealed after a single application of crack sealer? A: Most cracks are completely sealed after a single application of crack sealer,however some may require a second application of sealer should product settling occur. 15. Q: Will cracks that are sealed need to be sealed again? A: Yes, cracks that get sealed will likely need to be sealed again. With time, traffic,and weather cracks in your pavement slowly start to pull apart causing them to open again. Sealing should be considered a part of your routine pavement maintenance plan.
