Sealcoats And Repaving Asphalt

Do you want to repave or sealcoat your driveway? If you are going to repair your driveway because it is cracked and looking ugly and old, it is usually best to get started as soon as possible, rather than waiting. The truth of the matter is, repaving your asphalt from scratch is the only way to permanently solve problems with shifting soil, warping, or movement of the slab. That is, if there is actually a serious structural problem with your pavement, just adding a new layer of sealcoating is not going to be a permanent fix. Sealcoats do work well for less dramatic cracks.

Repaving Your Surface

If your asphalt is cracked clean through, and the slab is separated, the only real solution is to remove the existing asphalt. If your cracks are growing large, it probably means that your soil is moving. So, you basically need to remove the asphalt and take care of the problem in the soil. This requires some serious work on the soil, including excavation and leveling. When this is done correctly, the new pavement can be applied on top of a sturdier and more reliable surface. Obviously, this project is rather costly, but simply adding a sealcoat to your asphalt when there are such big problems is not a long-term fix.

In order to completely replace your pavement, it can cost several thousand dollars. Of course, you might also need to invest in extensive excavation, and soil preparation before the pavement can't be poured. The most common problem is that there are large tree roots growing underneath the soil, causing the surface above it to move and crack. The size and depth of the roots will largely determine how much the project will cost.

Fixing Smaller Problems with Sealcoat

However, if your surface is just cracked in a few places, and it seems that most of the blemishes are cosmetic, you can fix the problem much cheaper. You can reseal your surface by applying a liquid sealcoat that you buy a home improvement store. This is basically applying a thin coat of liquid asphalt directly on top of the old, cracked surface. The sealcoat will fill in most small cracks and holes and should be enough to fix cracks on the top surface permanently. It works well for cracks that only go down a couple of inches, and don't penetrate through the entire slab of asphalt.
