How Pin Piles Can Repair Your Foundation

If you’re having issues with your foundation, there are many different options for repair. Depending on your home’s situation and your budget, our team at NSquare, Inc. can inspect your home and provide a solution that’s right for you.  

Pin piles are a quick, affordable solution for foundation repair. They are small-diameter steel piles, or piers, that can be very useful in preventing structural settlement that occurs in weak or compressible soils. 

Benefits of using pin piles include:

  • Cost-effective
  • Little to no excavation needed
  • Does not require heavy machinery
  • Variable pipe length
  • Adaptable to site conditions

When to Use Pin Piles

Structural settlement and weak soils don’t need to derail your construction project or trigger an extensive excavation process. Pin piles are an easy installation that can provide a stable solution for your foundation. 

Pin piles are a very practical solution for many different foundation issues, but it’s best to use pin piles on projects that require lighter load transfers.

The equipment used to install pin piles is also very efficient and portable, which allows for easy installation in smaller, tighter spaces. Depending on your foundation’s situation, our team can inspect the area and determine what the best solution is for your home. 

Foundation Piles vs. Foundation Piers

While both piers and piles are effective solutions for foundation repair, there are instances where one may be more appropriate than the other. 

Depending on the extent of work that needs to be done to your foundation, our team at NSquare, Inc. can diagnose the issue and recommend the best possible solution for your home. 

Foundation Piers

Foundation piers typically have larger diameters compared to foundation piles and are typically used for heavier load requirements. Piers usually require more excavation to install and are also constructed with concrete. 

Foundation Piles

Foundation piles have a smaller diameter and can be quickly and easily installed for lighter load requirements. They can easily be installed in tight, constrictive areas, whereas foundation piers typically require more space for installation. 

Pin Pile Installation Process 

Pin piles consist of hollow, galvanized steel pipe that is typically 3-4 inches in diameter. They can be installed in tight quarters using a compact pneumatic hammer or a mini-excavator equipped with a hydraulic hammer.

The installation process for pin piles involves driving successive pile sections into the soil until the pile can’t be driven any further.

Pile sections can be joined to each other by field welding or using internal sleeved couplings. By driving each pile “to refusal,” the contractor ensures that the bottom of the pile is in contact with bedrock or solid, load-bearing soil.

Brackets or rebar can be used at the top of each pile. In a repair or “retrofit” application, a special foundation bracket can be installed to connect the top of the pile to the foundation, footing, or pool wall.

New Construction Applications

When pin piles are used in new construction applications, steel reinforcement (rebar) can be inserted into holes that are drilled in the top of the pile, or a cap plate can be installed. 

In these applications, the piles are cast into the structural concrete of the new foundation and the weight of the structure is transferred to stable soil at a greater depth.
