Types of Foundation Underpinning Techniques Used by Contractors
Foundation underpinning techniques are used to stabilize and strengthen existing foundations, preventing structural damage and ensuring the safety of buildings and occupants. There are three main categories of foundation underpinning techniques, each with its own advantages and disadvantages.
Main Categories of Foundation Underpinning Techniques
The three main categories of foundation underpinning techniques are: (1) deep excavation method, (2) soil stabilization method, and (3) foundation reinforcement method.
1. Deep Excavation Method, Foundation underpinning contractors near me
The deep excavation method involves digging a deep hole beneath the existing foundation to create a new foundation system. This method is used for severely damaged or unstable foundations, or when the soil is unstable.
- This method is used when the existing foundation is severely damaged or unstable.
- Deep excavation requires specialized equipment and expertise.
- River excavation may be used under a building and involves the removal of soil under the existing foundation using a process involving excavation underpinning
- Typically costs more to perform than other forms of underpin
A deep excavation project was carried out in Sydney Australia in 2000. Workers excavated beneath an existing three-story residential building. This allowed for deeper piers to be installed, thus providing a more solid and deep foundation for the residence, and giving a new home on top that was completely on an entirely deep solid base.
2. Soil Stabilization Method
The soil stabilization method involves treating the existing soil to increase its stability and prevent settlement. This method is used for lightly damaged or unstable foundations, or when the soil is prone to settlement.
- This method is used when the existing foundation has minor damage or when the soil is prone to settlement.
- Soil stabilization can help prevent costly settlement damage.
- It may not be as effective for severely damaged foundations.
Soil stabilization has been successfully used in various construction projects around the world, including the stabilization of soil for an 80-meter deep mine opening in Chile that utilized stabilization techniques including soil mixing and grouting in 2018. This allowed for a solid stable platform underneath the entrance and exit shafts of the mine.
3. Foundation Reinforcement Method
The foundation reinforcement method involves reinforcing the existing foundation using materials such as steel or concrete. This method is used for lightly damaged or unstable foundations, or when the soil is prone to settlement.
- This method is used when the existing foundation has minor damage or when the soil is prone to settlement.
- Foundation reinforcement can help prevent costly settlement damage.
- It may not be as effective for severely damaged foundations.
A project in New York, USA in 2015 successfully used the foundation reinforcement method to stabilize a damaged foundation. Workers installed steel cages around the damaged foundation to provide additional support and stability. The project involved the renovation of a historic building, and the foundation reinforcement method allowed for the structure to remain safe and secure throughout the renovation process.
