Is your driveway in need of repair? Many owners neglect this portion of the property until a problem arises. This is a mistake, and exterior contractors in Sun Prairie WI can be of help in rectifying the situation and offer advice on how to prevent future problems. Following are common issues to be aware of.
AlligatorCracking
When a driveway is exposed to a load it is not equipped to handle, alligator cracking may be seen. The surface, sub-grade, or base may not be strong enough to hold the load. It may be that the base or surface isn’t thick enough, or it could be a matter of poor drainage. In many cases, it is a combination of these factors. Homeowners first notice longitudinal cracking and alligator cracking appears when the driveway is severely distressed. As this is the result of a structural failure, a full-depth patch must be carried out to correct the situation.
Cracks Along the Edges of the Driveway
If a property owner notices cracks along the edge of the driveway, this is likely a sign of poor drainage. The cracks typically appear within one to two feet of the asphalt edge due to a lack of support. When this is the case, the base materials under the asphalt settle and become weaker. In addition, heavy traffic or lots of vegetation at the edge of the driveway can bring about the problem. The first step in resolving this issue is to identify the underlying cause. This may involve fixing drainage issues or removing vegetation. Once this has been done, the cracks need to be sealed or filled to prevent additional deterioration. In certain cases, the driveway may need patching to ensure the support issues are addressed.
Upheaval
If one spot of the asphalt is higher than the rest, it is like a sign of upheaval. When the sub-grade swells, this leads to upward movement in the area. Expansive soils often swell when they are extremely wet and can bring about this problem. In addition, when water collects under the pavement and freezes, it may lead to the same issue appearing. This is referred to as frost heave. Regardless of the underlying, a full-depth patch is needed.
