A foundation element, typically constructed of concrete, provides a stable and level base upon which a manufactured house rests. These support structures distribute the weight of the dwelling, preventing settling and ensuring structural integrity. For example, concrete pads or piers strategically positioned under the main frame beams are a common method of providing this support.
Adequate foundational support is crucial for several reasons. It protects against potential damage from ground movement, frost heave, and erosion. Properly installed supports also ensure that the home remains level, which is essential for the correct functioning of doors, windows, and plumbing. Furthermore, these supports can play a role in complying with local building codes and insurance requirements, influencing the longevity and resale value of the house.
The subsequent sections will detail the different types of support systems available, discuss installation best practices, address common problems encountered with existing supports, and provide guidance on inspection and maintenance procedures to ensure the long-term stability of the manufactured house.
1. Proper soil bearing capacity
Soil bearing capacity is a fundamental consideration when designing foundational support systems for manufactured homes. The ability of the soil to support the imposed load directly influences the design and implementation of the footers, impacting the overall stability and longevity of the structure.
-
Soil Composition and Load Distribution
The type of soil significantly affects its bearing capacity. Clay, sand, and loam exhibit different load-bearing characteristics. Consequently, the design of the footers must account for the specific soil composition at the site. In situations with low bearing capacity, larger or specialized footers may be required to distribute the weight over a wider area, preventing soil compression and settlement. For example, a sandy soil might necessitate wider footers than a dense clay soil for the same house.
-
Settlement Prevention
Inadequate soil bearing capacity leads to settlement, the gradual sinking or shifting of the home. Uneven settlement can cause structural damage, including cracks in walls, misaligned doors and windows, and plumbing issues. Footers designed with appropriate bearing capacity distribute the load evenly, minimizing the risk of settlement. Regular monitoring of the supports and surrounding ground is essential to detect any signs of settlement early on, allowing for corrective measures to be taken before significant damage occurs.
-
Drainage and Soil Stability
Soil moisture content significantly affects its bearing capacity. Poor drainage can lead to soil saturation, reducing its ability to support weight. Footers should be designed in conjunction with proper drainage systems to ensure that the soil remains stable. This may involve grading the surrounding land to direct water away from the foundation or installing French drains to manage groundwater. Maintaining stable soil moisture levels is critical for preserving the integrity of the footers and the overall foundation.
-
Building Codes and Regulations
Local building codes often specify minimum soil bearing capacity requirements for manufactured home foundations. These regulations are designed to ensure the safety and stability of structures. Footers must be designed and installed in compliance with these codes. Obtaining a soil test report and consulting with a qualified engineer are essential steps in ensuring compliance and avoiding potential legal issues. Failure to meet these requirements can result in construction delays, fines, or even the need to completely rebuild the foundation.
In summary, proper soil bearing capacity is inextricably linked to the design and performance of footers for manufactured homes. Adequate assessment and appropriate engineering solutions are essential to ensure the long-term stability, safety, and regulatory compliance of the dwelling. Ignoring soil conditions can have significant and costly consequences.
