What is Underpinning in Construction?
What is underpinning in construction? Well, that’s easy. When the foundation of a building becomes unstable or weakened, it poses significant risks to the entire structure. Underpinning is a vital construction process that reinforces and stabilizes foundations, ensuring that buildings can stand strong for years to come. In this blog, you’ll learn the fundamentals of underpinning, including why it’s necessary, the different types of underpinning methods, and how they address common foundation issues like settlement, water damage, and increased load demands.

Whether you’re dealing with a residential property or a commercial development, our experienced team offers customized solutions to meet the unique challenges of local soil conditions and environmental factors, ensuring your foundation is secure and long-lasting.
Protect Your Foundation and Secure Your Building’s Future with Piers and Piles
What is Underpinning in Construction?
So, what is underpinning in construction? Good question. Underpinning is a construction technique used to strengthen and stabilize the foundations of existing structures. It involves reinforcing or extending the depth of the foundation to support additional loads or to address foundation issues caused by settlement, soil movement, or poor initial construction. Underpinning is often necessary when the foundation’s structural integrity has been compromised, and it plays a key role in preventing further damage or collapse.
At Piers and Piles, we specialize in a range of underpinning techniques tailored to fit the unique needs of each project, ensuring that buildings in Long Island, Brooklyn, and Queens have strong, stable foundations that can withstand the demands of time and environmental factors.
Why Underpinning is Necessary
Underpinning is typically required for several reasons, including:
- Foundation Settlement: When the foundation sinks or shifts, causing cracks and structural instability.
- Increased Load Due to Building Extensions: When additional floors or building expansions increase the weight on the existing foundation.
- Soil Movement or Poor Initial Soil Conditions: Changes in soil conditions, such as shrinking, expansion, or poor compaction, can weaken the foundation.
- Water Damage Undermining Existing Foundations: Erosion caused by excess moisture from poor drainage, leaking pipes, or flooding can weaken the soil beneath the foundation.
Signs Your Foundation Needs Underpinning
If you’re unsure whether your structure needs underpinning, here are some common signs of foundation settlement:
- Cracks in Walls or Foundation: Visible cracking in brickwork, drywall, or the foundation itself.
- Uneven Floors: Floors that sag, slope, or feel uneven when walking across them.
- Doors and Windows That Stick or Don’t Close Properly: When doors and windows no longer fit within their frames, indicating movement in the structure.
- Visible Settling or Movement in the Foundation: Noticeable sinking or movement in the foundation over time.
These are early indicators that your foundation may need strengthening, and prompt action can prevent further damage.
Benefits of Underpinning
Underpinning provides a wide range of advantages for stabilizing and reinforcing foundations. By choosing the right underpinning method, you can safeguard your structure and prevent further damage.
Here are the key benefits of underpinning:
- Prevents Foundation Failure
- Strengthens Load-Bearing Capacity
- Stabilizes Structures Affected by Settlement
- Allows for Building Extensions or Additions
- Minimizes Long-Term Maintenance Costs
- Provides a Customized Solution for Unique Site Conditions
Underpinning ensures that your structure remains stable and secure, protecting your investment for the long term.
Types of Underpinning Methods
There are various underpinning methods used to address different underpinning needs, such as:
- Mass Concrete Underpinning: This traditional approach involves adding concrete beneath the existing foundation to reinforce its strength.
- Mini-Piled Underpinning: Mini-piles are driven deep into the soil to transfer the building’s load to more stable ground layers, often used in areas with limited access or deep foundations.
- Beam and Base Underpinning: A combination of beams and piles that redistributes the load across a broader foundation area, offering extra support for compromised structures.
Helical Piers for Underpinning
Helical piers are a modern, efficient underpinning solution that Piers and Piles offers for strengthening foundations. These piers are screwed into the ground, reaching stable soil layers to transfer the load of the structure. They are ideal for projects in urban areas or water-sensitive environments because they cause minimal disturbance to the surrounding site.
The benefits of using helical piers for underpinning include:
- Fast Installation: Quick, efficient setup without heavy excavation.
- Minimal Site Disturbance: Ideal for tight spaces or areas where disruption needs to be kept to a minimum.
- Suitability for Water-Sensitive Projects: Effective in areas with high water tables or unstable soil.
