When you think about all your driveway endured over the years, it really is amazing you have not had to replace it yet. It suffers through extreme hot and cold, rain, snow and sleet, drought, having stuff dropped or stored on it and almost daily it has multiple tons of weight put on it. There are signs you can do concrete driveway crack repair and signs you need to replace it; here are the signs you need to replace it.
Cracks start appearing on concrete driveways almost as soon as it is poured. They usually have no bearing on the integrity of the drive. Eventually, however, some cracks will appear that are too massive to implement concrete driveway repair.
When massive cracks appear, you can patch them, but eventually that will not be enough. More than likely, a long, wide and deep crack means your slab is settling or it has shattered because of extreme weather exposure. When that happens, you can try to patch them, but usually they expand too quickly for any patch to really do much good.
In this case, replacement is your only option.
Sunken or Dropped Concrete
When there are drainage issues beneath the concrete slab, eventually, the slab will settle and start to buckle. This happens because the concrete foundation beneath has eroded and created a pocket that time and gravity fill with your upper portion of your drive.
If the damage is not too extreme, you can try to inject various products beneath the surface to fill in any erosion gaps and raise the concrete slab. This type of solution, however, is expensive and does not always work. In many cases, the expense of injection makes the expense of redoing the drive a better deal.
When you replace the driveway, you will need to make sure you redo the foundation and drainage correctly to avoid having the same issue again.
Potholes and Pitting
If you drive heavy cars, trucks or machinery over the driveway, you can experience damage to the surface that grows into potholes. You also may experience frost heaves if you live in a cold region that break the concrete as they rise in the spring, leading to a pothole. Pitting is generally caused by a corrosive product, like salt or in some cases, natural deterioration.
Either can cause major problems for your drive. They can both be filled in, but if they are too large or keep coming back, replacement is a cheaper and better alternative.
Your drive takes a beating and in some cases, concrete driveway crack repair will work. In others, replacement is the best way to go.
