A house without a foundation is like a body without a backbone. If this analogy seems logical to you, let me add something else. It is okay not to use proper foundations as long as you do not intend to temporarily keep the structure.
A house needs a foundation to place its considerable weight on the base platform and to provide a flat surface for the rest of the construction. It also helps to lift the wooden floor from the ground, to avoid direct contact, to avoid moisture and termite infestation.
So really, the basis is what makes everything safe and secure. Let's look at why we need it and decide if you can build wooden houses without a foundation.
Why do you need a foundation?
Think of a square without a base. You might think it will be left on the side walls or something. The same thing happens with a house without a foundation. Your loading structure on the ground itself can adjust, but the safety concern is with lateral movement -f or an example - strong wind, tornado, earthquake or other calamities.
In addition, there is a chance that the entire construction will lose its alignment and eventually fall apart. The land contracts and expands based on the season. So there is always the risk of it falling apart, unless you build it on a firm concrete or a stone bottom.
More importantly, your building must maintain a standard code of compliance in each country. For example, under the standard California building code, you cannot build a residential home without a proper foundation.
Is it safe to live in houses without a foundation?
It is an obvious risk to live in a house without a foundation or with a shallow foundation. But these types of places are hard to find, especially when they are rare nowadays. But even if you own such a house, it is possible to extend the current foundation to a more stable level. The process is called substantiation.
What kind of foundation is good for a wooden house?
Whether you are buying a house or not, building a foundation should always be your focal point. These are of two kinds -
- Wooden foundation
- Concrete foundation
Each of these foundations has its own benefits. So let's talk a little about each of their strengths and weaknesses.
A concrete foundation resists moisture and lasts a long time. One of the reasons people go for concrete is that wood and moisture do not fit well together. That's because wooden foundations are not meant to sit directly above the ground. Moisture in the soil rots the wood in the long run.
On the other hand, concrete also has a risk of deterioration to some extent. Concrete, as we know, consists of pores that can suffer fractures if they continue to obtain an unbalanced pressure level. Poured concrete is less prone to cracking and also water resistant.
Wooden foundations offer greater savings than concrete ones, which are good for building low-budget homes. Concrete may also not be available in remote locations, so wood may be more convenient.
Obviously, concrete bases are much more expensive. Most people also add metal rods for extra strength before pouring concrete. This creates a solid and stronger foundation.
And, in addition, my personal opinion is that the wooden floor favors a better heating in winter than the concrete ones.
What kind of foundations can I get?
The usual types of concrete foundations are - a complete basement, accessible space, or slab on the surface.
A complete basement foundation is the deepest of the three and offers the largest floor space. The main advantage of this type of basement is the extra space it offers.
At the basement walls are about six feet high, which easily allows you to turn them into living spaces. It can almost double the living space of any house.
A disadvantage of this type of foundation is that it takes a long time to build and requires a lot of excavation to start building the foundation.
An accessible space foundation consists of short supporting walls that stand on their feet. The walls are shorter than the walls in a complete basement foundation. The good part is that it consists of enough storage space and promotes a sufficient flow of light.
These types of constructions are less expensive than a full basement because they require less digging, less foundation wall material, and obviously less labor time to build. The walls are made of cast concrete.
A concrete basement in the form of a basement is a single solid concrete slab that sits on the ground. It is generally 4 to 6 inches thick and consists of sand beneath it. The sand acts as a pillow and helps separate moisture from the slab.
Concrete slabs are good for a relatively warmer climate, where there is no frost on the ground. It is also inexpensive, easier to build and can protect against termite attacks.
But the most notable disadvantage is that the water inlet and outlet pipes are fixed in the plate. This means that the only way to fix it is to cut it.
Anything is possible when you build something. Ideally, this makes it unlikely and unwise at the same time. Similarly, you can build wooden houses without a foundation, but not for large infrastructure, obviously.
Your building is a safe investment in your life. It is something you invest in in the hope that it will last for a good number of years.
So before you think about building one, please make sure you have the right planning and resources to make it sustainable.
