Pier and beam foundations are a popular choice for many homes, especially in areas prone to shifting soil, like much of Texas. These foundations are known for their flexibility and easier access for repairs, plumbing, and electrical work. However, just like any other foundation type, pier and beam systems can develop problems over time. When issues arise, timely repairs are essential to maintain the safety and stability of your home. DuraTech Texas will walk you through the most common pier and beam repair techniques, how they work, and when they are necessary.
What is a Pier & Beam Foundation?
A pier and beam foundation uses vertical piers made from concrete, wood, or steel that are anchored into the ground. Beams are placed horizontally across these piers to support the weight of the house. Beneath the home, there is typically a crawl space that provides access to utilities. Pier and beam foundations are more forgiving to soil movement than slab foundations, but they can still experience issues like:
• Uneven floors
• Cracked walls
• Bouncing or sagging floors
• Moisture problems and wood rot
• Shifting or settling piers
Common Signs Pier & Beam Repairs are Needed
Before diving into the repair techniques, it’s good to recognize the signs of a failing foundation:
• Doors and windows that don’t open or close properly
• Gaps between floors and walls
• Sloping or “bouncy” floors
• Moisture or mold in the crawl space
• Cracks in the drywall or exterior siding
How Do You Fix a Pier & Beam Foundation?
Shimming the Beams: Shimming involves inserting thin pieces of material often steel or composite shims between the pier and the beam to fill in gaps and help relevel the foundation. Shimming is a short-term fix and is often used as part of a broader repair plan. It does not address deeper structural or soil problems.
Replacing or Adding Piers: If existing piers are damaged, decayed, or poorly spaced, they may need to be replaced or supplemented with new ones. This helps redistribute the weight of the home evenly. Proper placement and depth are key. Piers should be installed on stable soil or deeper bedrock when possible.
Beam Replacement or Sistering: If beams are cracked, rotting, or warped, they may need to be replaced entirely or reinforced using a process called “sistering.” Sistering involves bolting a new beam alongside the damaged one to provide additional support. All repairs should use pressure-treated lumber or steel to prevent future decay or infestation.
Re-Leveling the Foundation: Over time, parts of a pier and beam foundation can sink due to shifting soil. Re-leveling involves lifting sections of the foundation back to their original position and securing them. This process should be done slowly and carefully to avoid causing cracks or stress to the structure.
Drainage Correction & Crawl Space Encapsulation: Excess moisture is a common cause of pier and beam foundation issues. Installing proper drainage systems, such as French drains or sump pumps, and encapsulating the crawl space with vapor barriers can prevent future damage. Drainage improvements should always accompany structural repairs to prevent recurring damage.
Concrete Footing Installation: For homes with wooden piers resting directly on soil, upgrading to concrete footings or pads can greatly enhance the stability of the foundation. Footings must be properly sized and set below the frost line or into stable soil to prevent movement.
