Crack Filling & Sealing
A solid base is key to supporting the weight of traffic and extending the life of your pavement. Cracks begin to develop when the surface beneath the placement is not strong enough to handle the load placed on it. With newer pavement, you see more flexibility, as this pavement ages it can become fragile and more likely to crack. When cracks are not dealt with, they allow water to enter the surface and soften/erode the subgrade which leads to pavement failure. Water cannot be allowed beneath the surface of your asphalt. Using flexible hot rubber sealant, you can prevent water intrusion and slow further damage.
When it comes to sealing cracks, preparation and a clean surface is critical. Removing all dirt, moss, and debris to a proper depth is a must. For a long lasting seal, the walls of the crack need to be clean in order to provide a good bond to the sealant. To ensure you are receiving a superior job, we take the time to do the job with care, to do it right.
For crack sealing, we use quality HOT Applied rubber sealant. When a hot applied product is used, there is more of and involved process - what this really means is that you are getting a quality job done. With cold applied products, the flexibility only lasts for a short amount of time. Ensuring a longer lasting seal, you need proper prep and a highly flexible product.
Not all cracks are candidates for sealing. There is a sign of subgrade failure called "alligatoring", this is recognized by having a lot of cracks that interconnect. In most cases, these crossed cracks are filled with dirt or moss, acting as the "mortar" and is the only thing keeping the pieces of asphalt from falling apart. When cracks have reached this stage, the pavement has already lost structural integrity and trying to clean the cracks enough to take the sealant is not practical. The areas with the cracks should be removed and patched with hot mix asphalt. For very thin cracks, sealing can be used but there may not be enough material to enter the crack. It is expected to see re-opening of the crack as the pavement moves during temperature changes.
