Types of House Foundation

       There are different types of house foundation. The foundation is the first and most important step in building your new home. The foundation can vary depending on the location, climate, soil conditions and budget.

Basement Foundation

        It is the deepest  and most expensive foundation that begins with a hole of at least 8 feet deep. Structural foundation walls are places on concrete footings that run the perimeter of the basement where they pour beams, erect foundation walls, and pour a cement slab inside the walls. Basement foundations provide the advantage of an extra living space under the house. They are durable and resistant to fire and extreme weather.

 

Understanding the Different Types of Basement Foundations

  • Full basement foundation – the size of the basement is the same as the size of the house. Full basement foundation is also the most expensive foundation you can get.

      A slab foundation is the most common types of house foundation. it is an easy, quick and cheap foundation to build. it is actually a flat concrete slab that rests on the ground and is poured in one single piece. It is not preferred for cold weather place because of the ground getting frozen it may a crack.

     This is not a very popular foundation anymore. Wood foundations are often standard in northern areas. They can have a crawl space underneath, too. It’s also common to find basements that layer pressure-treated wood on top of concrete floors—but technically, such a combination would count as a concrete foundation.

 

 

 

 

Pier and Beam Foundation

 

Pier & Beam Foundations – Pros & Cons | URETEK Gulf Coast     This Foundation consists of concrete piers that are set deep into the ground to bear the weight of the structure. usually elevated about 18 inches, creating a crawlspace beneath the home. They are easily built and less expensive but not suitable for earthquakes and hurricanes. In many parts of Texas, pier and beam foundations are a necessity, especially in areas that receive heavy rainfall, seasonal moisture, and flooding. There us easy access to plumbing and electrical systems underneath the home, protection from flood waters and lower energy costs. The area under the house gathers a lot of moisture. It is recommended that your planting beds slope down, away from the house, which will allow rain and groundwater to drain the opposite direction of your foundation. Tree roots are consistently seeking moisture and can extend very far from the trunk.  In the summer, when Texas weather is usually very dry some types of trees can take up 150 gallons of water daily.  This can be dangerous to your foundation if the tree is too close. This foundation is good for manufactured or mobile homes.

     As the name implies, concrete block foundations are made of concrete or cinder blocks stacked together like bricks.

Brick/ Mortar Foundation

4 Major Problems and Expert Solutions for a Masonry Foundation      It was very common in the early 1900’s to use brick and mortar to build foundation walls. If you have an older home you may notice this is your foundation type. Red brick and mortar were a commonly used building material at the time. The problem with these foundation walls is that over time, they can become weak. Mortar can break down, bricks can start to peel. The soil around these foundations will exert pressure on them, and push them in. This occurs commonly when the brick and mortar breakdown. Sometimes you can just have the mortar or brick repair by a masonry specialist, but sometimes the walls need to have added support.

 

 

Stone Foundation

  Stone basements are no longer common types of house foundation, but you might find them in older houses. These types of house foundations use a mixture of stones and a mixture of cement to form a solid barrier. They can crack and chip, so most builders shy away from such materials in modern homes.

 

 

 

 

 

 

Stilt Foundation

Stilt Houses: 10 Reasons to Get Your House Off the Ground

   

       Stilt supports generally are used in houses on steep hillsides, and involve tall 4 x 4’s holding up the house on the downslope side. These stilts are generally very flexible, which makes the building vulnerable to earthquake damage. Stilts can be strengthened by adding diagonal braces or plywood walls between the stilts. Additional bracing should be added at the corners beneath the main structure.
