Before the 1960s, houses were literally installed in the air. In fact, before the refinement of slab technology, many of the houses were lifted by pier and beam structures. Nowadays, pier and beam foundation, also known as post and beam, aren’t so famous. However, they are still the norm in some places, particularly in the areas that are prone to rain and flood. While your home is designing, consider using pier and beam foundations to get the best out of the advantages they have over slab. But, they also carry some of the disadvantages, you should look out for.

The Pros

  • Pier and beam foundation, also known as post and beam foundation help in elevating homes to keep the flooding and moisture at bay.

  • There exists a crawl space between the home and the ground which is high enough, which is where the name was derived. It also lets the utilities like plumbing and electrical wiring or units that can be easily installed and accessed in case of any issues.
  • The biggest advantage of pier and beam foundations is— if there are any plumbing problems in the slab foundation, for instance, there is a need to break open the cement floor to have access to the damaged pipes. But pier and beam foundation, on the other hand, has fewer foundational problems than slab and they are also affordable to repair.
  • Under the home, there is also a teeny bit of insulation from the air, this helps you in saving the energy costs. Many people prefer installing wooden platform over a concrete floor. Yes, it does attract termites, but they are actually easier to detect.

The Cons

  1. Pier and beam foundation make the floors prone to sagging, creaking and bouncing.
  2. Pier and beam foundation accumulates rain and creates moisture problems.
  3. Pier and beam foundation promotes poor ventilation.
  4. Pier and beam foundation makes the wood prone to mildew, mold, and rot.
  5. Pier and beam foundation makes access for bugs and rodents.

Poor design of the structure adds more mayhem to the problem, particularly the inappropriate spacing between the pier and beams and shim failures when inferior materials are used. Luckily, rectifying these issues is often affordable than slab foundation. In fact, slab foundation begins to crack, and sometimes it is also impossible to fix it.
