HOME FOUNDATIONS AND WHY MATERIALS MATTER

Excerpted from – Source:  Realtytimes.com Staff writers.

“The typical single family home can weigh anywhere from 80,000 to 160,000 pounds.  Foundations provide a solid base for a home’s weight, help to ensure the house stays level and provides a base for construction to take place.  Foundations matter, and so does the material that they’re made of.

Before buying or constructing your home, it’s important to be familiar with foundations to help you better understand how to prevent damage or make necessary repairs.

The most common material used is concrete – by far.  Typically poured or constructed with a series of cinder blocks, concrete is fairly inexpensive, easy to find and produce, and strong.  Although poured concrete is prone to cracking, these repairs are often affordable and easy to have done, especially if it is being done from the interior.  Drawbacks of concrete vary based on the type of foundation.  Cinder blocks may buckle over time and can involve expensive repairs.  Poured concrete requires a mixer on site to perform installation, possibly adding costs if a concrete facility isn’t close by.

Pre-built walls typically consist of of studded wall construction that’s been coated in a concrete layer.  It installs quickly, is always level and makes discovering problems easier.  However, pre-built walls are more expensive than other types of foundations.

Stone and Brick are commonly found in older homes.  Stone foundation usually aren’t equipped with the right type of drainage systems.  Brick foundations, though typically thick and adequate, tend to degrade over time and are also prone to mortar issues.

FOUNDATION TYPES:  Foundations don’t just come in many materials – they take different shapes.

  • BASEMENTS.  Cold weather climates are the most popular location for basement installation because the foundation of the home needs to exist beneath the frost level in order to sufficiently support it.  They’re typically made of poured concrete, and many also serve as a place where home appliances are located.  Occupants often take advantage of the extended headroom to turn the area into additional living space.  BUT…prone to flooding, fully underground basements can be costly if your yard doesn’t quickly absorb or drain rainfall.  Basement walls and floors are also susceptible to cracking, which require repair to keep moisture out and maintain structural integrity.
  • SLABS.  A slab is nothing more than poured concrete that exists on a grade of land.  Slab foundations are popular in warm weather climates, where water tables are higher.  It’s installed about a foot underground and usually reinforced with steel.  Slabs are a cheaper type of foundation and, unlike a basement, reduce flooding risk.  However, slabs are prone to cracking and can also provide difficulties for incorporating heating and cooling ducts into the home.
  • CRAWLSPACES.  Crawlspaces are foundations that exist beneath a home with limited headroom.  Though headroom is at a premium, it’s typically enough to store certain appliances, piping, ductwork, and more.  The majority don’t permit the additional living space of a basement because they’re approximately two to four feet high.  Installation is cheaper than a basement, but more expensive than a slab.  Other big disadvantages include susceptibility to moisture issues and serving as a favorite place for pests and rodents to seek shelter.  (And radon gas may accumulate).  The good news is that you can waterproof your crawlspace.

Worried that your foundation may be in need of repair?  Signs that your foundation may need attention include:  misaligned exterior doors and windows, cracks in stonework, sheetrock and floors, bulges in the floor, or interior doors sticking or jamming.  Consult a professional if you think your foundation is in trouble.
