SmartJack® Crawl Space Stabilizers

The stability of a structure is paramount to its longevity and safety. Uneven foundation settlement can cause significant problems, ranging from cosmetic cracks to structural damage. SmartJacks are a prevalent method for stabilizing settling foundations and fixing sagging floors.

Technical Specifications of SmartJacks:

• Weight Capacity: SmartJacks boast a maximum allowable capacity of 30 kips (30,000 pounds) when assembled. However, extensive independent lab testing revealed ultimate capacities ranging from 56 kips to 90 kips, demonstrating exceptional strength reserves.
• Adjustable Height: The jacks feature a threaded steel shaft that allows for precise height adjustments during the lifting process, enabling contractors to level the foundation with high accuracy.
• Material Composition: SmartJacks are constructed from high-strength, triple-layer, in-line galvanized steel for superior durability and corrosion resistance. This coating process includes hot-dip zinc galvanizing, a conversion coating for enhanced protection, and a clear organic topcoat for aesthetics. Additionally, the inner pier tube features a zinc-rich coating, and other steel components receive a standard zinc-plated finish for comprehensive corrosion protection.

Advantages of Professional Installation:

While SmartJacks offer a seemingly straightforward solution, professional installation is crucial for several reasons:

• Structural Assessment and Jack Placement: Improper jack placement can lead to uneven lifting and exacerbate foundation issues. Professional contractors possess the expertise to assess the structure's specific needs and determine the optimal locations for jack placement to ensure balanced lifting and prevent further structural damage.
• Foundation Type Expertise: Different foundation types require specific jacking techniques. Professionals are familiar with various foundation systems and can tailor the installation process accordingly. This ensures the jacks are properly anchored to the foundation for optimal support.

Hydraulic Systems and Safety Considerations:

SmartJacks utilize a hydraulic system for controlled lifting. Professionals understand the intricacies of this system, ensuring proper pressurization for safe and efficient lifting. Furthermore, they prioritize safety measures such as using lifting braces and adhering to procedures to minimize the risk of accidents during the installation process.

Soil Bearing Capacity and Long-Term Stability:

The practical load bearing capacity of the SmartJack® system is predominantly determined by the underlying soil. Professionals understand this and may employ well-compacted crushed stone or steel plates to bolster support, especially under conditions where higher bearing pressure is required. This method also facilitates the absorption and distribution of lower pressures across the existing soils. In most scenarios, except those involving extremely soft conditions, achievable allowable loads typically range between 10 to 15 kips, with minimal anticipation of future settlement. Should settlement occur, the all-thread rod allows for readjustments, ensuring continued stability.

Versatility and Limitations:

SmartJacks excel in crawl space support, offering comprehensive support and future adjustability. It's important to note that SmartJacks are designed for axial compression loads and not recommended for applications requiring lateral load resistance.

Conclusion:

SmartJacks are a valuable tool for foundation stabilization, but their effectiveness hinges on proper installation and an understanding of soil bearing capacity. By partnering with a qualified professional contractor, homeowners can ensure their foundation receives the expert attention it deserves, resulting in a safe, structurally sound, and level home.
