Wondering what a pier foundation is? If so, don’t hit that back button because you’ve landed on the right page. This article will cover what a pier foundation is, how pier foundations are built, their pros and cons, and more.
What is a Pier Foundation?
A pier foundation is a foundation that lifts a structure off the ground creating a space underneath. You’ve probably seen houses near bodies of water raised high on piers. They look kind of like they’re sitting on a deck. Those are pier foundations. They protect homes from flooding and the rising tide. However, pier foundations aren’t just for structures near water…
When walls enclose the space underneath a pier foundation, it becomes a crawl space foundation, a type of pier foundation that sits between 18 inches and 3 feet off the ground. Until the 1960s, crawl space foundations were popular in the US. Although they aren’t as popular as they once were, they’re still being built today. Homeowners like pier foundations because they offer easy access to the home’s plumbing and wiring.
Older pier foundations were built with wooden piers. Today, concrete piers are more popular. Pier foundations are well-suited to regions with expansive soil because a structure sitting on a pier foundation is less affected by soil conditions and soil movement.
