Portable buildings offer a convenient solution for homeowners and business owners alike. They can be used for storage or as additional space for various purposes. However, before you can install a portable building, you must have a sturdy foundation to support it. In this blog post, we’ll discuss two popular options – concrete vs. skids – to help you make an informed decision on which foundation is best for your needs.
Concrete Foundation
One of the most popular foundation options is concrete. A concrete foundation is always recommended for larger portable buildings as it will provide maximum stability and long-term durability. If your building is being used for commercial purposes, such as a workshop or office, a concrete foundation is almost always required by law.
Concrete foundations require a flat surface to be poured over and must be level to prevent cracking and shifting. Additionally, a concrete foundation requires a significant amount of preparation and may require permits. The cost of a concrete foundation is also higher than other options, making it a more significant investment. However, a concrete foundation is a long-term solution that will require little maintenance over time.
Here are some of the different types of concrete foundations to consider:
Floating Concrete Slab Foundation
A floating concrete slab foundation is a type of foundation where the slab is not attached to the ground or footings with any anchors or bolts. Instead, it is placed and poured over a cushioning layer of sand or gravel. This foundation option is ideal for level or gently sloping ground. Some of the advantages of a floating concrete slab foundation include:
- Easy and quick to install
- Cost-effective compared to other concrete foundation options
- Suitable for DIY installation due to its simplicity
However, the disadvantages of a floating concrete slab foundation include:
- Unsuitable for uneven or sloping ground.
- Not ideal for regions with expansive soil that can exert pressure on the slab and lead to cracks or shifts.
- Lacks the durability and stability that a slab foundation with footers offers.
Concrete Slab Foundation with Footers
A concrete slab foundation with footers is a type of foundation where the slab is supported by a series of footings that penetrate deeper into the ground. The footings provide extra support and stability to the slab, making it ideal for larger buildings and uneven or sloping ground. Some of the advantages of a concrete slab foundation with footers include:
- Durable and long-lasting
- Suitable for large or heavy structures
- Provides better insulation compared to other foundation options
However, the disadvantages of a concrete slab foundation with footers include:
- Expensive compared to other foundation options
- Requires professional installation
- Takes longer to install compared to other types of foundations.
Pier and Beam Foundation
A pier and beam foundation is a type of foundation that consists of a series of small concrete piers (or columns) and wooden beams that support the floor. This foundation option is ideal for regions with expansive soil, as it can quickly adapt to changes in soil conditions. Some of the advantages of a pier and beam foundation include:
- Suitable for uneven or sloping ground
- Better ventilation and insulation
- Allows for easier access to plumbing and electrical wiring
However, the disadvantages of a pier and beam foundation include:
- More costly when compared to other concrete foundation options
- Requires frequent maintenance and inspections due to the risks of pest infestation and moisture damage.
Deck Block Foundation
A deck block foundation is a type of foundation that involves placing concrete blocks with vertical posts on the ground. The posts support the beams that support the floor. This foundation option is ideal for light-duty structures such as tiny homes, sheds, or workshops. Some of the advantages of a deck block foundation include:
- Affordable and easy to install
- Suitable for DIY installation
- Versatile and can be adjusted to different sizes and shapes
However, the disadvantages of a deck block foundation include:
- Lacks the durability and stability of other concrete foundation options
- Unsuitable for large or heavy structures
- May not meet local building codes for permanent structures.
Skid Foundation
Another popular foundation option is the skid foundation. Skids are typically 4×4 or 6×6 pieces of lumber that are used to create a base for the portable building. The skids are placed on a level surface, and the building is anchored to them using bolts and straps. Skids are a great option for those who do not have the budget for a concrete foundation or are not in need of a structure that will last for many years.
One of the main advantages of skids is that they allow for easy transportation of the building. If you need to move your building to a different location, it can easily be done by placing it on a trailer or a truck bed. Skids also require less site preparation, which can save time and money. However, skids may not be suitable for buildings that will be subjected to heavy loads or high winds.
Factors to Consider
When choosing a foundation for your portable building, there are several factors to consider. These include the size and weight of the building, the intended use of the building, the climate in your area, and your budget. It’s important to do your research and consult with a professional when making this decision.
