5 Differences Between Slab And Slab On Grade Foundations
There are many different types of foundation systems that can be used for a home or business. Two of the most common are slab and slab on grade foundations. In this blog post, we will discuss the five main differences between these two types of foundations. Keep reading to learn more!
What Is A Slab Foundation?
A slab foundation is a type of foundation that is built by pouring concrete onto a level surface. This concrete is then left to cure, or harden. Once it has cured, the slab will be one continuous piece that supports the weight of the structure above it.
What Is A Slab On Grade Foundation?
A slab on grade foundation is similar to a slab foundation, but there is an additional layer of concrete that is poured on top of the ground before the main slab is poured. This layer of concrete is called a grade beam. The grade beam helps to distribute the weight of the structure more evenly and prevents the slab from cracking.
Now that we have covered the basics, let’s get into the differences. Here are the five differences between the two foundations:
Difference #1: Cost
There are several reasons why slab foundation is less expensive than slab on grade foundation. First, slab foundation does not require as much concrete. Additionally, slab foundation does not require a vapor barrier or insulation, which can further reduce costs. Finally, since slab foundation is typically thinner than slab on grade foundation, it requires less labor to install. These cost savings can add up, making slab foundation a more affordable option for many homeowners.
Difference #2: Thickness
Slab on grade foundations are typically thicker than slab foundations. There are a few reasons for this. First, slab on grade foundations are typically used in areas with higher soil loads, such as those near bodies of water or in highly marshy areas. The extra thickness helps to distribute the weight of the structure more evenly and prevents the foundation from settling unevenly. Additionally, slab on grade foundations are often used in areas with higher temperatures, as the extra thickness helps to insulate the structure from the heat. Finally, slab on grade foundations are typically used in structures that are subject to high levels of vibration, such as factories or warehouses. The extra thickness helps to absorb some of the vibration and prevent it from damaging the structure.
Difference #3: Strength
Slab on grade foundations are typically stronger than slab foundations. First reason is that the soil underneath a slab on grade foundation is less likely to settle over time than the soil underneath a slab foundation. Second, the weight of the house is evenly distributed over the entire surface of the slab on grade foundation, whereas with a slab foundation there is often a heavier concentration of weight around the perimeter. Finally, slab on grade foundations typically have more reinforcement than slab foundations, which further increases their strength and stability.
Difference #4: Settlement
Slab on grade foundations are less likely to settle than slab foundations.Slab on grade foundations are typically wider than slab foundations, which gives them a greater area of contact with the ground. This increased contact area helps to distribute the weight of the building more evenly, which reduces the likelihood of settlement.
In addition, slab on grade foundations are usually constructed with a concrete base that is thicker than the concrete used for slab foundations. This increased thickness helps to provide greater support for the weight of the building, which again reduces the likelihood of settlement. Finally, slab on grade foundations are typically constructed with reinforcement bars (rebar) that help to further increase their strength and stability. All of these factors together make slab on grade foundations much less likely to settle than slab foundations.
Difference #5: Waterproofing
Slab on grade foundations are easier to waterproof than slab foundations because they are built on top of a concrete slab. This means that there is less chance for water to seep through the foundation and into the home. Additionally, slab on grade foundations have a smooth surface which makes it easier to apply waterproofing materials. Finally, these types of foundations are less likely to crack, which can also lead to water infiltration.
Now that you know the five differences between slab and slab on grade foundations, you can make an informed decision about which type of foundation is right for your home or business. If you have any questions about these types of foundations, or any other type of foundation, please contact a licensed foundation contractor in your area.
