The next thing to take into account is the type of foundation you’re working with. The design considerations of a shallow foundation will be much different than the considerations in a deeper foundation.
Which one are you working with? What do you need to pay attention to? Here’s everything you need to know.
- Shallow Foundation
A shallow foundation is a type of foundation that transfers the structural load to the earth that’s very close to the surface. There are many types of shallow foundations: you may find concrete footings, spread footing and mat-slab foundations regarded as shallow foundations.
Shallow footing design can be a completely acceptable decision for home foundation design. However, design consideration of a shallow foundation needs to take into account the fact that the home will be more prone to settling if not crafted properly.
With a shallow foundation, it’s even more important that you maintain your weight load to the proper amount. Otherwise, you’re certainly going to end up with a home that eventually sinks and settles into the ground.
- Deep Foundation
As opposed to a shallow foundation, a deep foundation transfers the structural load to earth that’s much further into the surface. Typically, this is done to help avoid the design considerations of a shallow foundation that would allow for less weight.
A deep foundation often uses a pier foundation, such as push piers or helical piers. The piers push far underneath the structure and are installed directly into the load-bearing rock far underneath the home. That maintains the structure more fully.
Deep foundations can certainly hold much more weight than shallow foundations. However, they may not be necessary for all homes, especially if the home is relatively light and on a type of soil that can hold a substantial amount of pressure.
- Can You Change a Foundation Type?
What if you run into problems with your shallow foundation and want to change it into a deep foundation? Is it possible for you to cut off issues you’re having with shallow footing design by simply changing the home into a deep foundation?
Although it’s not always simple, it is possible. A JES expert can install a pier system underneath the foundation to essentially “convert” it from a shallow foundation into a deep foundation.
This process can be incredibly effective if you’re dealing with a home that’s trying to bear too much weight. Especially if you notice the home is starting to sink near the end of the building process, you will want to talk to a JES expert to see whether you can use a pier system to push the home back up.
