Slab-On-grade Foundation

A slab-on-grade foundation is one form of structural foundation that transfers construction loads to the ground directly in front of the structure, and not to a series of deeper levels or a super depth. The foundation of a structure is actually formed by the settlement that occurs when a building is built. This settling takes place on the interior side of the structure. Foundation creep can develop when settlement continues beyond the structural framing. In this case, settlement will occur along the exterior of the foundation and can cause damage to the supporting walls of the home or building.

One reason that slab-on-grade foundations are so efficient is that the soil beneath the structure remains relatively constant throughout the life of the structure. On an asphalt slab, for example, the soil density is such that it will settle into a fairly regular pattern. So, when the soil around the structure begins to settle and then bulge, the weight of the settlement will push the soil outward. As the foundation gradually pushes outward, the vertical position of the slab rests directly on the earth.

For many reasons, it is very important to keep the soil around the foundation fairly constant, especially in wet areas. For one thing, constant settling of the soil will mean that slab-on-grade foundations are more apt to slip. When soil moves from beneath the structure, there will be little resistance to the weight of the soil, which can quickly turn an attractive area of your landscape into a potential hazard. Any movement of soil away from the foundation will increase the amount of water that will run off into the drainage system, causing greater problems down the road.

In addition, a slab-on-grade foundation rests directly on the concrete, which is another potential weak point. The amount of force that concrete is able to exert will vary depending on its particular configuration. While straight concrete is usually the weakest link in a slab-on-ground system, curved edges will cause the concrete slab to exert far greater force. Contractors may install a concrete slab that lies directly on a layer of gravel, which serves as a moisture barrier. The gravel serves as a first layer of protection against any groundwater seepage, preventing the water from reaching the base of the structure. The gravel will also make the foundation feel a bit smoother, especially when driving rains begin.

Because it is impossible to have a perfectly level surface when building a new house, engineers typically build their structures at an angle. In order to allow for this aspect, builders often dig out large concreted “shaking zones” where the structure will rest against the terrain. The concept of the shaking zone has actually become quite popular in the construction industry. Typically, the shake zone is located directly underneath the structure and is lined with crushed stone. It functions as a buffer between the concrete slab and the environment, providing a level, smooth surface for walkways and other surfaces.

In most cases, basements are left dry because there is no structural reason that water can’t enter a basement. If basements are located near a plumbing system, the constant water could easily enter the structure through an unsealed gap below the foundation. A properly planned Slab-on-grade foundation will seal off any leaking or other issues that may occur. Additionally, if the site of the foundation is in an area that is susceptible to ice dams, then a slab foundation will keep the water inside and away from the basement. Proper drainage will prevent water from draining into a basement and eventually causing it to collapse.

Another reason why basements should not be considered as just places to cool off and hang out is because of the effect it can have on the value of a home. When a basement has a slab foundation, it’s much more difficult for a homeowner to get a mortgage or sell a house because it shows a mortgage lender that the homeowner is very serious about their location. With basements that are not properly sealed, any leaks or excess moisture will damage the interior. This can affect the overall value of your home and cause a homeowner to consider selling or building a new home.

There are many different types of basement foundations that can be implemented into any building design plan. When choosing the best foundation for your basement, it is important to keep all of these aspects in mind. By learning about the different types of foundation options, you will be able to make an informed decision regarding which one is best suited for your situation. Although slab foundations are the most popular option, there are other building methods that can provide the same amount of durability and longevity. If you’re interested in learning more about any of these building methods, you can contact a professional foundation contractor to discuss your options. They can help you find the right foundation for your home and make sure that you have chosen the perfect building method for your basement.
