Concrete driveways are built to last, but like other types of driveways, they are bound to show signs of wear and tear from the weather and vehicular traffic. One of the most problematic repair issues you may face with your concrete driveway is sinking.
A sinking driveway typically occurs due to the existence of significant voids between the concrete surface and the sub-grade layer. The voids are created when soil from under your driveway is washed away due to erosion.
Over time, this will result in the formation of cracks on the surface of your concrete, which will expedite the damage to your driveway. Fortunately, there are ways to fix a sunken driveway.
Here's an easy fix you can try.
Keeping water away from your concrete sub-grade
Flooding on your landscape after heavy rain may weaken the foundation of your concrete driveway, eventually washing away sections of the sub-grade section. If not addressed on time, the problem may escalate and become expensive to repair.
Ensuring that the drains that direct rain out of your landscape are working properly will allow you to make repairs without worrying about rain causing further damage to the sub-grade section.
Mudjacking isn't new — it has been the traditional method for fixing sunken concrete slabs. This concrete repair method involves drilling the concrete surface to allow enough space to fill the voids within the concrete sub-grade. It is an easier and less expensive process and will have your concrete driveway back in top shape within no time.
Instead of ripping off the entire sunken section of the driveway, you will only need to mix sand and cement or soil then pump the mixture to fit in the voids using the drilled space. If done well, the mixture will fit perfectly and settle within the spaces and voids, thus preventing further damage to your concrete paving.
Using a good quality caulk for cracks on the concrete surface
Cracks in your concrete driveway are an entry point for water and other debris, which over time, compromise the structural soundness of your concrete sub-grade. This may compromise your concrete sub-grade through weakening its foundation, causing a hollow feeling whenever driving or walking on your driveway surface.
Using a good caulk will ensure the concrete surface of your driveway is impermeable to water, preventing damage to the sub-grade.
As a homeowner, you want your concrete driveway at its top shape. A sinking driveway is a tell-tale sign that your concrete driveway needs repair service. It is imperative that you act fast to avoid major damage to your driveway, which is costly to fix. Also, keep in mind that preventative maintenance is vital to avoid most repair issues.
