It is important to ensure that a basement foundation has a solid base in terms of renovations and construction learn more here. It involves strengthening the existing foundation and stabilizing it to ensure the structural integrity of a structure. This technique will be especially useful in older homes and buildings that have foundation issues or are undergoing renovations.
Why Underpinning a Building is Required
There are several factors that can force the foundation of a basement to be underpinned. One of the main reasons for foundation shifting is due to the natural settling or sinking caused by soil. This can result in cracks on walls, uneven floors and other structural issues. Also, soil moisture changes, poor building practices, and nearby excavations can compromise the foundation stability.
The need to increase a foundation’s capacity for bearing loads is another common reason. This is usually required when adding more floors to the building or installing heavy machinery. The homeowner can increase the safety of their home by ensuring that it can safely support any additional weight.
The Underpinnings Process
Underpinning the basement foundation usually involves a few steps. First, an assessment is made of the existing foundation to determine how much damage has occurred and what the best course-of-action should be. This may include soil analysis, structural evaluation, or other diagnostic measures.
As soon as the assessment is completed, the actual work of underpinning begins. This involves excavating the soil under the existing foundation, and replacing it with a more stable material. There are a number of methods to underpin a building, including
1. **Mass Concrete Substrate**: This method, which is traditional, involves digging sections under the foundation and filling it with concrete. It’s a simple, cost-effective solution that works for many types and sizes of building.
2. **Beam & Base Method** This technique involves installing a reinforced beam of concrete below the foundation. The beam is then supported by concrete bases. It gives the structure additional stability and strength.
3. **MiniPiled Underpinning** This method is employed when soil conditions and access are limited. It involves driving small pilings into the soil to support the base, creating a deep and sturdy foundation.
Benefits of Underpinning
Underpinning has many benefits for homeowners. It ensures structural integrity and safety by preventing further damage. The property value will also increase, as a solid foundation is one of the main selling points for potential buyers. Additionally, basement underpinning creates additional usable living space or storage spaces. The process of underpinning basement foundations is essential for maintaining stability and safety in a building. Underpinning can be used to fix foundation issues and prepare for future renovations.
