When you are building a home, starting with a solid foundation is huge. If you form this part of your home carefully and accurately, then the rest will follow suit. There are several different types of foundations to consider with your new property such as whether to have a crawl space, a full blown basement, or just the above-ground floors, and these options mainly depend on the style of your home, the location and soil type.
In the following article by Wisely Green, the best foundation choice for your new home is explained further:
What’s the Best Type of House Foundation for Healthy Home Construction? | Wisely Green
A house foundation takes the loads from the roof, walls and flooring and transfers them to the soil for proper support. It’s as important as any other element of construction, especially if you are building a healthy home or using green building techniques.
Not only is there the importance of load bearing and proper construction design, but there is also the issue of how to build a house foundation in order to avoid mold growth and other toxicities that can eventually invade the upper levels of a home.
In general construction, the type of foundation is typically chosen based on local climate conditions and construction conditions of the area. However, when choosing to build a healthy house, there is more to consider such as:
- Moisture control
- Termite avoidance
- Healthy materials
- Soil conditions
- Radon mitigation
- Energy efficiency

There are a few choices when putting in the walls for a basement. You can use concrete block, poured concrete walls, or foam block walls. The latter is very energy efficient and the following video shows a time lapse of the foundation of a home from start to finish. Starting at 4:40, you can see them start to incorporate the foam blocks:
As mentioned above, the location and soil type are critical for you foundation. The most impermeable types of earth aren’t necessarily the best because of the lack of drainage, but sand isn’t a good foundation either. After excavation, the building contractor has to be sure to build up the area with the proper mix of soil to make a solid structure.
This article discusses the importance of using the correct combination of dirt for your property:

Question: What type of soil is good for a foundation for buildings or houses?
Answer: In both cities and the countryside, selection of sites with the best soil is an important engineering decision in the building process. Whether you live in a house, condo, or apartment, your home is connected to the soil. Your school, the building where you work, the stores you shop in—all of them are built on soil, and often with it.
Building foundations need to be on stable and strong soils. Soils range in strength. Some soils are able to support a skyscraper, while other soils are not able to support the weight of a human. If the soil under a building is not stable, the foundation of the building could crack, sink, or worse–the building could fall!
The strength and stability of soil depend on its physical properties. Soil with good structure is more stable. Clay textures are often more stable than sand textures because they have better structure. However, a mix of particle sizes (and pore sizes) is best for engineering (just as it is best for growing crops). It is also important that soil is stable through wetting and drying cycles, so that expanding soil does not crack roads or foundations. Some clay minerals, from a family called smectite, are more likely to shrink and expand during wetting and drying cycles than minerals from other families, such as kaolinite.
Most people aren’t able to excavate the basement for their anticipated building project. It takes special equipment and knowledge, so you are wise to call a local building contractor to manage this initial phase for you. Done right, you will avoid cracks in the foundation that can cause a domino effect for the rest of the home.
