Remediation of Sagging Crawl Space Foundation with the SmartJack® System – A Case Study from South Mountain

Abstract: This paper details a case study involving the remediation of a significantly sagging crawl space foundation in a residential property located in South Mountain. The challenge presented by a dirt floor crawl space with compromised structural integrity, manifesting as uneven and sagging floors, is discussed. The implemented solution, utilizing the advanced SmartJack® System, is thoroughly described, highlighting its engineering principles for stabilization and elevation correction. The methodology, including the creation of engineered fill bases and precise column adjustment, is presented. The successful outcome, characterized by restored floor elevation, enhanced structural stability, and improved homeowner safety and peace of mind, underscores the efficacy of the SmartJack® System in addressing common crawl space foundation issues.

1. Introduction

Crawl spaces are integral components of many residential foundations, providing a buffer between the ground and the living space.1 However, they are susceptible to various issues that can compromise the structural integrity of the entire home. Common problems include inadequate support, soil settlement, moisture intrusion, and pest infestations, all of which can lead to sagging floors, compromised structural stability, and a reduction in indoor air quality.2 This paper focuses on a specific case where a homeowner in South Mountain experienced significant floor sagging due to issues within their dirt-floor crawl space. The remediation efforts, employing the SmartJack® System, are presented as a successful engineering solution to these challenges.

 
 

 

2. Problem Statement

The subject property in South Mountain exhibited a clear and concerning problem: visible sagging of the interior floors. Investigation revealed that the root cause lay within the crawl space, which featured an exposed dirt floor and evident signs of compromised support. The existing support system, whether inadequate original construction or degraded components, was no longer effectively carrying the load of the superstructure. This structural deficiency manifested as:

  • Uneven and Sagging Floors: Creating an aesthetic issue and posing a tripping hazard.
  • Compromised Structural Integrity: Placing undue stress on the framing and potentially leading to long-term damage to the entire home's framework.
  • Safety Concerns: Directly impacting the safety and livability of the residence.

The urgency for an immediate and effective intervention was paramount to restore the home's structural integrity and ensure the safety of its occupants.

3. Solution Implementation: The SmartJack® System

To comprehensively address the identified structural deficiencies, the SmartJack® System was selected and implemented. This advanced foundation repair system is specifically engineered for stabilizing and lifting sagging floor joists and beams in crawl space environments.3 Its design and installation methodology are rooted in providing robust, adjustable, and long-lasting support.

 

 

The implementation process involved the following key steps:

  • Site Preparation: The crawl space was assessed to identify precise locations for the SmartJack® installations. Any debris or obstructions were removed to facilitate access and ensure proper installation.
  • Base Creation with Engineered Fill: A critical component of the SmartJack® System's effectiveness lies in its stable foundation. At each designated SmartJack® location, a solid, stable base of engineered fill was meticulously created. This involved excavating a small area, compacting the underlying soil, and then introducing and compacting layers of high-strength, engineered aggregate. This engineered fill provides a robust and unyielding foundation for the steel columns, effectively distributing the load and preventing future settlement.
  • SmartJack® Column Installation: Once the engineered fill bases were established, the heavy-duty steel columns of the SmartJack® System were positioned directly atop these prepared foundations. The columns are constructed from galvanized steel, offering excellent corrosion resistance and strength.
  • Precise Adjustment and Elevation Correction: The SmartJack® System incorporates an adjustable threaded rod mechanism. Using specialized tools, each SmartJack® was meticulously adjusted to lift the sagging floor joists and beams back to their original, correct elevation. This process was performed gradually and systematically to avoid over-stressing the structure and to ensure an even lift across the affected area. The precise adjustments were critical in eliminating the floor bounce and achieving a level floor.
  • Secure Fastening: Once the desired elevation was achieved, the SmartJack® components were securely fastened to the floor joists and beams, ensuring a permanent and stable connection.

4. Results and Discussion

The implementation of the SmartJack® System yielded immediate and significant improvements to the South Mountain home. While an "after" photograph is not provided in this context, the observable results were a testament to the system's efficacy:

  • Restored Floor Elevation: The most prominent outcome was the visible leveling of the previously sagging floors. This directly addressed the primary concern of the homeowner, eliminating trip hazards and restoring the aesthetic appeal of the interior.
  • Enhanced Structural Stability: By providing direct, robust support to the floor joists and beams, the SmartJack® System significantly enhanced the overall structural stability of the home. This reduced stress on the framing and mitigated the risk of long-term structural damage.
  • Reduced Floor Bounce: The precise adjustment and solid base of the SmartJack® units effectively minimized and often eliminated the noticeable floor bounce that the homeowner had been experiencing, contributing to a more solid and secure feel within the home.
  • Improved Homeowner Confidence: Beyond the technical improvements, the successful remediation provided the homeowner with significant peace of mind, knowing that their crawl space foundation was now robustly supported and their home's safety was restored.

The SmartJack® System proved to be an effective and durable solution for the specific challenges presented by the sagging crawl space in South Mountain. Its engineered design, coupled with precise installation techniques, ensures long-lasting support and addresses the root cause of structural instability in crawl space environments.

5. Conclusion

This case study demonstrates the successful application of the SmartJack® System in remediating a sagging crawl space foundation in a residential property. The system effectively addressed the challenges of compromised structural integrity and uneven floors by providing robust, adjustable, and stable support. The meticulous installation process, including the creation of engineered fill bases and precise column adjustments, was instrumental in achieving the desired outcome of restored floor elevation and enhanced home stability. The SmartJack® System stands as a proven and reliable solution for homeowners facing similar crawl space foundation issues, offering both structural integrity and long-term peace of mind.
