Welcome to our comprehensive guide on foundation piering. In this article, we will delve into the process involved in foundation piering and explore the numerous advantages it offers. Foundation piering plays a pivotal role in ensuring the structural integrity of buildings, providing stability, and mitigating potential damage caused by foundation issues. Whether you are a homeowner or a construction professional, understanding foundation piering will empower you to make informed decisions when faced with foundation problems. So, let’s get started!

Understanding Foundation Piering

What is Foundation Piering?

Foundation piering, also known as underpinning or stabilization, is a technique used to reinforce and stabilize a building’s foundation. It involves installing sturdy piers beneath the foundation to provide support and prevent further settlement or movement. Foundation piering is commonly employed when a foundation has experienced damage due to soil issues, excessive water, poor construction, or age-related wear and tear.

Types of Foundation Piering

Foundation piering techniques vary depending on factors such as soil conditions, the type of structure, and the severity of the foundation problem. The two main types of foundation piering are:

  1. Steel Push Piers: These are hydraulic-driven steel tubes that are pushed into the ground until they reach load-bearing strata. Steel push piers offer exceptional strength and are suitable for various soil types.
  2. Helical Piers: Helical piers consist of steel shafts with helical plates. They are screwed into the ground, providing stability and support. Helical piers are commonly used in areas with weak soil or when the load needs to be transferred to deeper, more stable layers.

Signs You Need Foundation Piering

Determining whether your property requires foundation piering is crucial. Look out for these common signs that indicate foundation problems:

  • Cracks in walls, floors, or ceilings
  • Doors and windows that stick or won’t close properly
  • Uneven or sloping floors
  • Bulging or leaning walls
  • Gaps between walls and the ceiling or floor
  • Excessive moisture or water intrusion in the basement or crawl space

If you observe any of these signs, it is advisable to consult a professional to assess your foundation and recommend appropriate solutions, which may include foundation piering.

The Foundation Piering Process

Foundation piering involves a systematic process to achieve a stable foundation. Let’s explore the various steps involved:

Site Evaluation and Preparation

Before any work begins, a thorough evaluation of the site is conducted by foundation experts. They assess the severity of the foundation problem, determine the appropriate piering technique required, and draft a plan for the installation process. Site preparation involves marking utility lines, clearing obstacles, and ensuring a safe work environment.

Excavation and Access Points

Excavation is necessary to create access points for installing the piers. The process involves digging pits around the foundation, exposing the footings or slab. Care is taken to avoid damaging the surrounding areas, plants, or structures. The depth and width of the excavation will vary depending on the specific requirements of the project.

Pier Installation

Once the excavation is complete, the piers are installed. For steel push piers, hydraulic equipment is used to drive the sections into the ground until they reach a load-bearing stratum beneath the foundation. Helical piers are screwed into the ground at a predetermined depth and torque to ensure stability and load-bearing capacity.

Lifting and Stabilization

After the piers are in place, hydraulic jacks or similar lifting equipment is used to raise the foundation to its original position or to a predetermined level. This process helps compensate for any settlement that may have occurred over time. The lifting is carefully monitored to maintain the structural integrity of the building.

Filling and Restoration

Once the foundation has been lifted and stabilized, the excavated areas are backfilled. Care is taken to compact the soil properly to avoid future settlement or shifting. The site is then restored, ensuring that landscaping and other features are reinstated to their original condition.

Advantages of Foundation Piering

Foundation piering offers several advantages that make it a preferred choice when dealing with foundation problems. Let’s explore the benefits:
