3 Factors that Determine How Thick a Concrete Driveway Should Be

Concrete is a popular material for driveways because it is versatile and can conform to any shape or size a homeowner wants. The appropriate thickness can also be poured to optimize its function and durability. But how thick should a concrete driveway be? Here are some factors that play a huge role in determining that number.

Type of Soil

In Las Vegas, the type of soil varies in different areas. You could hire a soil engineer to check and evaluate the type of soil you wish to build your concrete driveway on and to help design a driveway appropriate for the type of soil you have. For properties with expansive soil, contractors often install a structural base first, about 3 to 6 inches, before pouring concrete. A thickness of 4 to 6 inches of concrete is then poured and leveled. For areas where the soil is more firm and could pass as a structural base, 4 inches of concrete will do.

Function of the Driveway

But if garbage trucks, delivery trucks, or other heavy vehicles often drive and park on your driveway, then the contractor might recommend a thick concrete driveway for extra strength and durability. Although this is a factor that needs to be considered, contractors highly recommend keeping heavy vehicles from driving and parking in your driveway to prevent damage.

Installation Budget

The minimum requirement for most concrete driveway thickness is 4 inches. If you want to enhance the structural capacity of your driveway, then you could add one or two more inches to it. An inch added to 4 inches is enough to boost the capacity of a driveway to accommodate heavy vehicles by 50 percent. However, it is important that you understand that an additional inch will also incur an additional 20 percent to the total cost of the installation project. Make sure that you are willing to invest more for a thicker and stronger driveway.

Thickness is a major factor in installing concrete driveway installation. Before you make a decision, consult a pro and discuss the three factors discussed in this article. They should be able to create a plan or a design that will work best for your property’s soil type, the main purpose of your driveway, and how much your budget will be.
