Crawl Space Jacks

Crawl Space Jacks - SmartJack® Technical Information

Crawl Space Support in All of Florida

Crawl Space Support in All of Florida

The Foundation Supportworks Smart Jack™ is a supplemental support system for crawl space applications. The SmartJack® effectively supports sagging beams and floor joists caused by:

  • Length of span greater than spanning capability of the members,
  • Floor load added after construction, exceeding design values, and
  • Weakening of members over time due to high moisture and rot.

The SmartJack® may also be used as a supplemental column support where an existing column and pier foundation has settled.

Allowable Capacity

The allowable system capacity of the assembled SmartJack® steel components is 30 kips (30,000 pounds). Axial compression tests completed at an independent laboratory on the assembled SmartJack® system, with and without a pre cast concrete footing, resulted in ultimate values between 56 kips and 90 kips.

While the rigidity and strength of the SmartJack® components benefit installation and overall product stability, the allowable load applied to the SmartJack® system will nearly always be limited by the bearing capacity of the existing soil.

The well-compacted crushed stone or recycled concrete base is a proven method to increase support for the higher bearing pressure condition immediately below the concrete footing, and then to absorb and distribute lower pressures to the existing soils. Except in extreme soft conditions, allowable loads on the order of 10 to 15 kips are typically achievable without future appreciable settlement.

Should settlement of the SmartJack® system occur, adjustments are made easily by extending the all-thread rod.

Crawl Space Jacks

Strong and adjustable. Crawl space jacks provide all the support you need and can be adjusted in the future.

The SmartJack® is designed to support axial compression loads only. The SmartJack® should not be used in applications where the system is intended to resist lateral loads.

Corrosion Protection

The tube steel used for the SmartJack® is manufactured with a triple-layer, in-line galvanized coating.

This coating process consists of:

(1) A uniform hot-dip zinc galvanizing layer

(2) An intermediate conversion coating to inhibit the formation of white rust and enhance corrosion resistance;

(3) A clear organic top coating to further enhance appearance and durability. The inside of the pier tube also has a zinc-rich coating.

The remaining steel components of the SmartJack® come standard as zinc-plated in accordance with ASTM B633, "Standard Specification for Electrode-posited Coatings of Zinc on Iron and Steel".
