Prior to 1950, the majority of homes used wood as an exterior finish and for flooring. Poorly draining properties are more likely to have foundation issues and movement regardless of the age of the foundation or the home.Įconomics and architecture were the driving forces to constructing a slab on grade foundation as opposed to a pier and beam foundation. We recently worked on leveling project for a 100 year old home that was supported on cedar posts and just recently had them replaced. The cedar is a naturally preserved wood that is able to resist the decay due to moisture for a much longer period of time than other wood species. Since wood decays with moisture, it is common practice to use cedar posts for the piers. The first is the structural integrity of the wood pier. The performance of the pier and beam foundation is dependent on two major factors. A true pier and beam foundation consists of pedestals (piers) embedded into the ground and spaced at an average of 5 to 6 feet on center with wood beams supporting the floor joists. ![]() To understand how a pier and beam foundation performs it is important to discuss how the foundation is constructed and what level of performance to expect from this foundation. Performance of a Pier and Beam Foundation With the advancements in concrete design, contractors and developers started to construct floating slabs as opposed to pier and beam foundations. Before 1950, the pier and beam foundation was the most economical and practical foundation for homes. ![]() Before the use of the conventional slab on ground or floating slabs, the pier and beam foundation was the typical foundation constructed to support a house.
