What is a Pier & Beam Foundation?

A pier and beam foundation, also known as a post and beam or crawl space foundation, is elevated above ground level, creating a “crawl space” underneath the house. Here’s how it functions:

  • Piers: Deeply embedded vertical supports, typically concrete or brick, that anchor into the ground for stability and help prevent the house from shifting or settling.
  • Beams: Horizontal supports resting on the piers, spreading the house’s weight evenly across them.
  • Crawl Space: This substantial gap between the ground and the house’s base allows easy access to utilities and acts as a barrier against ground moisture, lessening damage risks.

Advantages of pier and beam foundations include:

  • Adaptability: They’re great for areas with shifting soils as they can be adjusted relatively easily compared to slab foundations.
  • Utility Access: Simplifies maintenance or changes to utilities without extensive digging.
  • Moisture Prevention: The elevated design helps protect against flooding and reduces the chances of mold and rot.

Regular inspections are essential to check for wood rot, pests in the crawl space, and pier alignment.If you’re unsure about your home’s foundation type or its condition, contact Bay Area Underpinning for a free inspection.

Our Approach to Pier & Beam Foundation Repair

Bay Area Underpinning’s approach combines advanced methods, deep expertise, and a commitment to homeowners. We begin each project with a detailed inspection to identify specific issues with your pier & beam foundation. Based on this, we tailor a repair strategy to ensure your home’s stability.

Our solutions for pier and beam foundation repair include:

  • Support Jacks: At Bay Area Underpinning, we use crawl space support jacks for robust foundation support. Our team measures the space under your home to accurately place these jacks, offering long-lasting stability.
  • Sonotubes: Acting as hollow concrete columns, sonotubes are strategically placed around the foundation. Our process involves removing the broken or old pier and beam footing and replacing it with a strong concrete form. This technique not only revitalizes the foundation but also boosts its support capability.
  • Shoring: This method adds extra support to worn foundations by attaching new beams, joists, and piers.

We guarantee precision in every service, ensuring reliable results for homeowners.
