If you are looking for your own concrete driveway, or if you are looking around for a contractor's offer, you may be confused about the thickness of your driveway. This article will discuss the lane thickness.
weight
The concrete thickness required for the driveway depends on the weight of the vehicle that will use it. Most homes with cars, trucks or SUVs can use four-inch thick concrete slabs. This is based on a vehicle weighing 10,000 pounds. Less in Egypt. As an example, a normal SUV or pickup truck weighs between 4,000 and 6,000 pounds, and even a boat on a trailer does not exceed 8,500.
If you plan to place a heavier vehicle on the driveway, you will see a thicker lane. For the average family, this larger vehicle is usually a motor home. Most RVs start at 10,000 pounds. Up to 30,000 [no need to consider the extra weight loaded into it]. So if you want to find a location for your personal RV, you will need to add 5 or 6 inches of thickness to your concrete driveway.
Better prevent cracks?
The concrete will rupture. period. However, thicker doesn't always mean you get a guarantee of less cracking. Usually, cracks are caused by other factors related to thickness, but not Cause By thickness. For example, as described above, if too much weight is applied to a thin concrete driveway, it will greatly cause cracking. Another major cause of cracks is that the driveway has no solid foundational benefits. Concrete plays an optimum role on solid surfaces that are not moving. In areas where the ground is mainly sand or clay, severe cracking is more likely to occur. Also, in this case, a thinner lane suffers a faster speed than a thicker lane. However, a good contractor will know how to lay the proper foundation for the concrete slab, so no matter whether the driveway is 4 inches or 5 inches, precautions are taken to prevent excessive cracking. Similarly, the use of wire mesh or steel bars [rebars] in laying concrete will make the concrete more durable, regardless of the thickness of the slab.
price gap
Although the pricing of the work itself has many variables and may fluctuate across the country, the specific cost is about 20% from a 4 inch thick slab to a 5 inch thick slab. However, adding extra inches can increase the weight capacity of the lane by 50%.
If you choose a thickness of 4 inches, you will save money because the thickness does not require rebar to strengthen it. Most contractors use the above-mentioned wire mesh, which is obviously cheaper and still very effective.
