Your choice of a house foundation will depend on the type of soil of the building site. Houses which are constructed on poor conditions of the soil may need a deep foundation, while most construction sites only need shallow ones. As a matter of fact, the weather is another big factor to look into when choosing a foundation. In addition to that, some kinds of the foundations do not work well in cold or flooding conditions. Consult with a professional structural engineer or experienced and highly trained Wichita Falls foundation repair service provider when you are constructing a house in order to discuss what kind of foundation suits you best.
Poured Concrete Foundations
The poured concrete foundations are the most common kind of house foundations. Furthermore, the concrete slab foundation is usually formed by pouring some few amounts of concrete with larger edges in order to provide support. The slab basically rests on the bed of crushed gravel in order to improve drainage. Additionally, the slabs are poured all at the same time and are perfect for use in some areas where the grounds do not freeze during winter season.
The name already speaks to itself that the frost-protected foundations protect concrete from further damages due to intense temperature. The T-shaped foundations are the traditional choice for cold places. Hence, this method of creating a foundation gives additional support for the concrete slab foundation with the concrete footings which extend under the frost lines. In addition to that, the frost-protected shallow foundation or the FPSF gives extra protection without having to dig under the frost lines. The frost-protected shallow foundation uses insulated concretes to protect the slab foundation from the frost damages. Aside from that, the frost-protected shallow foundations have already been used for over five thousand buildings in some local areas and over a million houses in Europe.
Permanent Wood Foundation
The permanent wood foundation has been utilized since the year 1960s. This kind of foundation are using treated lumber and plywood as a substitute material for stem wall foundations, basement and crawl spaces. This foundation is consisted of preservative-treated wood which is easy to install, very light in weight and decay-resistant. As a matter of fact, the permanent wood foundations do not need concrete casting or pouring that makes the procedure much more accessible. Aside from that, these foundations are very easy to insulate as well as moisture-resistant. Over 300,000 homes already use this type of foundation.
The raised foundation is very important in some coastal places which receive huge amounts of rain as well as are very vulnerable to flooding. The raised foundation needs careful planning due to the fact that it should be able to both provide protection from the moisture and support the home as well. There are actually two kinds of raised foundations: the stem wall and the pier-and-beam. The pier-and-beam foundation utilizes brick blocks or concrete which are reinforced with footings. On the other hand, the stem wall foundation is quite similar, except that its footings are continuous instead of spaced.
