The concrete driveway is composed of a series of concrete slabs that are formed by concrete material being poured into a wire mold. The actual concrete mixture will be poured onto a layer of wire mesh atop a few layers of other materials. One recommendation is to reinforce the sides of the driveway with rebar. Another option that is to use pieces of lumber that are the right width to reinforce the height of the driveway.
The layers of the driveway below the concrete are usually threefold. The first layer is the sub-grade, usually composed of natural soil. The second layer is the sub-base, composed of small stones with a length of up to 1.5 inches. The third layer is the base, composed of gravel.
When you choose a concrete contractor, you can specify the quality of the materials that will be used to build the driveway. The contractor should ensure adequate drainage of the soil, gravel, and stone layers below the concrete surface. Sufficient drainage is essential to the durability of the concrete driveway.
The type of soil that sits on your property will determine how much work is needed to prepare the soil foundation for the driveway. For example, some types of soil will be able to function as the sub-grade, sub-base, and base of the driveway. Other types of soil may require the contractor to dig out so many inches of soil before the sub-layers of the driveway can be laid. Therefore, soil quality is an important consideration when choosing a property on which to build.
There are other paving options besides concrete, including asphalt and custom pavers. Choosing the right driveway construction depends on your budget and your desired look for the entrance to your home. Remember, a quality driveway increases your homes curbside appeal.
