At Rio Bravo Home Inspections, we take inspecting the foundation very seriously. There are usually two different types of foundations that we come across, but with many different ways to construct or repair them. We take true importance in understanding how these different types are constructed and how they have been repaired. Below you will find photos and descriptions of what we’ve found in previous inspections and information that we’ve studied.
What is a pier and beam foundation? A pier and beam foundation is an alternative to a slab foundation. In a pier and beam foundation, a concrete pier is reinforced with steel (rebar), forming a strong cage within the pier. The piers are set atop a concrete pad that also has been reinforced with steel rebar.
What’s a slab foundation?
A slab foundation is made of concrete that is typically 4″–6″ thick in the center. The concrete slab is often placed on a layer of sand for drainage or to act as a cushion. Houses built on a slab lack crawlspaces, and there is no space under the floor.
What’s a post tension foundation?
Post-tension concrete slabs are used to create a monolithic (single pour) slab that is stronger than a traditional slab without reinforcement. This is achieved by laying out high-strength steel cables in a crisscrossed grid pattern throughout the foundation prior to pouring the concrete.
