The foundation of this home is part of the overall design element. The natural terrain dicated the choice of foundation but the way it was built dictated the overall "look" of the home.

Trivia Question: True or False: China poured more concrete between 2011-2013 than the US poured between 1901 - 2000? (See the answer at the end of the newsletter.)

Focus on Foundations: The purpose of a foundation is to transfer the weight or load of the building to the earth and also to resist the load imposed on the building by the earth. In this months Oak Leaf, we will discuss the pros and cons of the most common types of foundations to help you in your decision making process while planning your new home.

The home along the Atlantic coast was built on pilings.

What material and type of foundation is most common? Concrete block or poured in place concrete is the most common residential foundation material. Preservative treated wood, precast concrete and other methods are also available. Concrete slab on grade is the most popular foundation in the Southeast. Basements are most common in the East and Midwest. Crawlspaces are common in the Northwest and Southeast. Pile foundations are commonly used in coastal flood zones to elevate structures above flood levels or eliminate issues caused by sites with steep slopes or weak soil.

According to NAHB (Ntl Assoc of Home Builders) 56% of all new single family homes started in 2014 were on a slab foundation. 28% had a full or partial basement and 15% were on a crawl space.

Here you can see all the various types of foundations.

Type of foundation is closely tied to the climatic conditions where you are building: Foundations have to be built to extend at or below the frost line. So in colder areas, houses are usually built with a basement as the frost depth may be several feet below the ground. Slab foundations are quicker and cheaper to construct if you are building in a warmer climate and have a flat building site.

This shows the geographic distribution of the use of basements in 2014.

Are foundations different for a log home? This is a very common question that we hear from our prospective buyers. No, you do not typically require any bigger or deeper footer or foundation wall for a log home vs a stick frame home. The log home may weigh more than the frame home but that weight is disbursed evenly along the foundation. In contrast, a frame wall has all the weight bearing every 16" or 24" depending on the stud spacing. This creates the need for the foundation to be designed and engineered to withstand a high psi for those stud locations. So a typical foundation wall is "over engineered" in between those studs.

A one story log home built on a slab can be built quickly and at a lower cost per square foot.

What to consider when choosing a foundation for your new home: First is the building site. The slope of the land, the type of soil, the ease of excavation, the potential view and how you will have to allow for storm water run off are all factors determined by your site. A slab is not a good choice if you have a steep slope. If you are building on solid rock, a basement may be very expensive as it will require blasting. If you want to get your home "up high" for a better view, a basement may be a good choice. Many times the site makes your decision very easy!

Second is your personal preference. Some people do not want a basement because they don't want to go down stairs or they think it encourages collections of "junk." Others like the extra storage space or the ability to finish the basement into additional living space. Some people like the solid feel of a concrete slab floor. Other people don't like to walk on concrete all the time.

Third is your preference for the design or type of HVAC system. If you are building in a northern climate and don't need air conditioning, a slab with radiant floor heat may be perfect for you. If you want central forced air heat, a crawlspace or basement would probably be a better choice. Some of the newer split systems are making this less of an issue however.

The basement construction for this home "raised" the home up so that it provided a spectacular view from the main level.

This poured in place basement is the perfect choice for this steep lot. The "walk out" of the back wall allows for natural light and air into the lower level for a more comfortable and inviting environment.

What is the difference between a basement and a crawlspace?

They only have two differences: the height of the wall and a concrete vs a rock floor. As you can see in the photo on the right, a basement wall is typically 8' to 10' tall. A crawlspace wall may be only 3 or 4ft tall. A basement will typically have a solid concrete floor (like a slab.) A crawlspace can have a slab floor also but rock is usually most times. Obviously it would be a poor choice on the lot on the right to build with a crawlspace instead of the basement.

Alternative foundation systems There are various foundation wall systems that are available today. The two photos above and two below show a Superior Wall system being delivered to the job site, installed, and then finished. If you are planning to finish your lower level, these can be an excellent choice and actually save money. A drier basement and less concrete cracking is also given as advantages to these systems. Check locally to find what is available in your area. An experienced installer is very important.

Long Term Considerations: You may also want to consider other factors in making your decision. One is resale. If most houses in your area have a basement, it may not be wise to use a slab as it may lower your appraisal now and in the future. And a basement always gives future buyers the ability to add more square footage by finishing off the space. Another consideration is long term maintenance and repair. Shifting soil and other factors can crack a slab over time. Mechanical systems that break or misfunction can be very expensive to fix in a slab as the concrete is poured around them.

So as you can see, there is not a "Best" Foundation to use for your new home. It is simply the matter of which is "Best" for you and your building site!

This large home under construction in Florida shows the simplicity of slab construction. Lower risks of flooding, leaking gasses and mold are advantages of slabs. A long term consideration however is tree roots. They can grow under the slab and cause major damage to the foundation.

This home was built on a slab on the Missouri State Fair Grounds in Sedalia, MO. If you live in Missouri, go to the Fair this month and check it out! Built in 1987, it serves as a Senior Rest Area and is property of the State of MO.

Answer to Trivia Question: TRUE! China produces and consumes about 60% of the world's cement. In three years, they used 6.6 gigatons. From 1901 to 2000 the US used 4.5 gigatons. Think about everything we built in that 100 years. The skyscrapers, the Interstate highways, the dams like Hoover Dam. And they used all that and more in 3 years.
