“24 Therefore whosoever heareth these sayings of mine, and doeth them, I will liken him unto a wise man, which built his house upon a rock: 25 And the rain descended, and the floods came, and the winds blew, and beat upon the house; and it fell not: for it was founded upon a rock. 26 And every one that heareth these sayings of mine, and doeth them not, shall be likened unto a foolish man, which built his house upon sand: 27 And the rain descended, and the floods came, and the winds blew, and beat upon the house; and it fell: and great was the fall of it.”
It is important to understand that the foundation of the home is one of the most significant aspects of the home. Foundation types vary, but the importance of the foundation should never be over looked.
Concrete contains very interesting characteristics when force is applied. Concrete is able to with stand a lot of compressional force, but when it is pulled (i.e. tension force) it is very weak. However, when you add the steel reinforcement (rebar, wire mesh, steel fibers, etc) it helps protect the concrete by adding tensile strength.
Something to keep in mind about foundations is that cracking does not always mean that your foundation is failing. When concrete is poured, it goes through a chemical process. That chemical process gives off heat. Once the concrete begins to cure (dry), then that heat and extra water particles need a way to get out. Sometimes the drying effect will cause hydration cracks.
Another type of foundation is a pier and beam foundation. Sometimes referred to as a block and beam. Although there may be different materials used between block and beam vs pier and beam, the functionality of the foundation should be the same. This type of foundation typically elevates the structure, typically around 18”, off of the ground. Utilities are often running under the structure through this crawl space. Unlike a slab foundation, a pier and beam foundation substructure does not rest directly on the ground.
In conclusion, regardless of the type of foundation you use, it is important that you choose to build a house upon a solid foundation. Buying or building a house may be one of the most expensive things you do in your life, you want to make sure that it rests on a foundation that will be strong.
