Foundations are crucial for any structure as they transfer the weight of the building to the ground. However, with time and due to various reasons such as soil erosion, subsidence, water damage or even initial poor construction, foundations may weaken or become unstable. In Lafayette, LA - an area known for its humid subtropical climate – these issues are not uncommon. The high levels of rainfall can lead to excessive moisture in the soil which can cause it to expand or contract dramatically; this process is often referred to as "soil movement" and it can lead to cracking or settling in foundations.
When these types of foundation problems arise, underpinning provides a solution by reinforcing or extending the existing foundation depth or breadth so that it rests on more supportive soil strata or distributes its load across a greater area. Here's how underpinning works and why it's an effective method for solving foundation problems:
### 1. Assessment:
The first step in underpinning is a thorough assessment by structural engineers who will identify the extent of foundation damage and determine the appropriate underpinning method needed based on soil conditions and building requirements.
### 2. Choosing an Underpinning Method:
There are several methods of underpinning including mass concrete underpinning (also known as pit method), beam and base underpinning, mini-piled underpinning among others. The choice depends on factors like load requirements, access constraints, depth needed for stability etc.
#### Mass Concrete Underpinning:
This traditional method involves excavating sections beneath the existing foundation and filling them with concrete in a sequential manner to create a new base. This is generally suitable where shallow excavation is required.
#### Beam and Base Underpinning:
A reinforced concrete beam transfers the load of the wall above onto concrete bases constructed at strategically located points.
#### Mini-Piled Underpinning:
Where ground conditions are variable or access is restricted for larger rigs needed for traditional piling methods; mini-piles might be used which can extend up to 15 meters below ground level providing support deep within stable strata.
