In general concrete driveways have a life span of about 30-40 years depending on the location and weather conditions. Many factors contribute to your driveway's durability, such as; proper subgrade, adequate reinforcement, correct concrete thickness, and a host of other outside elements.
If you are starting to notice signs that it may be time for a concrete repair or an entirely new installation, this article will explain three signs that your concrete driveway may need to be replaced.
There is no exact science as to what constitutes as a crack that is too deep, too wide, or too long for repair. It is always best to defer to a qualified concrete contractor and get their opinion on how best to repair or replace the damaged concrete. If the contractor finds that the cracks cannot be repaired, then replacing the damaged concrete becomes the only option. In some cases, just the damaged section can be torn out and replaced. In others, it may be best to replace the entire drive if grading is an issue.
Thankfully there are a few different techniques that can be used to fix this. The first method is mudjacking. This is where concrete or another strong material is pumped under the sunken slab to provide support and to level out the piece. This process isn't always the solution in which case a replacement is the only option available.
The upheaval caused by tree roots causes water to pool on the concrete and not drain properly. This can lead to unneeded freezing and thawing in the winter months, which can cause the concrete driveway to deteriorate much faster than an undamaged driveway.
