Over 5,000 EverJacks Installed (as of August 9, 2025)
All EverJacks are visually inspected and load tested to their allowable load capacity of 8,400 lb before leaving the warehouse. See manual on Ultimate Load Capacity of 25,000 lb and Factor of Safety = 3.0.
I invented this product after doing hundreds of crawl space assessments. I knew there had to be a better way so I put pen to paper in 2020 to come up with a way to eliminate the footings needed in crawl spaces.
Now the EverJack has the ICC ES Report and is the only ICC evaluated product and only code compliant product that can be placed directly on the crawl space soil without the need for a footing. Typically, installation times are around 5 minutes for the EverJack Original and 1 to 2 minutes for the All-In-1 EverJack.
The ability to fine-tune the height through an intuitively designed cap bolt allows for secure and precise installations, making it an ideal choice for various applications, including deck supports.
To help you every step of the way, we provide comprehensive resources, including an installation manual and the ICC ESR 4900 report.
As you consider the EverJack for your foundation needs, remember that it’s already been embraced by contractors across the country, highlighting its proven track record with thousands of EverJacks already installed.

USES
The Ever-Jack is used for the support of post columns in under-floor spaces, such as crawl spaces, and is compliant with the International Building Code and International Residential Code.
Ever-Jacks are used as individual, isolated footings supporting downward vertical loads only.
Ever-Jacks Uses:
- deck supports
- crawl spaces
- manufactured homes (HUD/HCD approval is forthcoming)
DESCRIPTION
The Ever-Jack is a molded composite footing assembly comprised of components manufactured from a proprietary blend of Advanced aerospace grade composite material.
The base component is a circular, ribbed pad with an internally threaded cylindrical shaft which extends vertically from the center of the base. The cap bolt component has a cylindrical, externally threaded shaft and a circular top cap plate. The cap bolt threads into the Ever-Jack base, allowing for adjustability of the cap bolt height through rotation of the cap bolt. The boot disc component is a circular disc with interior flanges arranged in a square shape. The boot disc fits atop the cap bolt component.
DESIGN AND INSTALLATION
- Design:
The Ever-Jacks are designed as surface rigid footings that transmit, uniformly to the supporting soil or concrete foundation material, the applied downward vertical load imposed by a nominal 4×4 [3.5 by 3.5 inches (89 by 89 mm)] wood post. The base of the post is supported by the top cap of the Ever-Jack cap bolt and is centered on the top cap with the Ever-Jack boot disc. The load is transferred from the post, through the Ever-Jack cap bolt, into the Ever-Jack base, and distributed on the ground surface. Allowable loads are controlled by the type of supporting soil or capacity of foundational materials, as applicable. The Ever-Jack design load must not exceed the allowable downward vertical loads shown in Tables in the Manual (See other webpages of this website)
The Ever-Jack has been evaluated for use at temperatures at or above -20⁰F (-29⁰C).
- Installation:
Installation of the Ever-Jack must be in accordance with this report, the applicable code and the report holder’s published installation instructions.
The Ever-Jacks must be installed at grade level, on soil or concrete, in underfloor spaces, such as crawl spaces. Before placement of the Ever-Jack, the ground surface must be made uniform as described in the report holder’s installation instructions to ensure direct, uniform, level bearing of the Ever-Jack on the supporting soil or foundation material, as applicable.
The Ever-Jack boot disc must be placed in the top cap of the cap bolt. The cap bolt is then raised as described in the report holder’s installation instructions to receive the base of the wood post. The wood post must have a solid base which bears uniformly on the top cap of the Ever-Jack cap bolt. The post base must be centered on the top cap using the boot disc. The final height the cap bolt must be such that the thread engagement between the cap bolt and Ever-Jack base is not less than 1 inch (25.4 mm).
CONDITIONS OF USE:
The Ever-Jack product described in this report complies with, or is a suitable alternative to what is specified in, those codes listed in Section 1.0 of this report, subject to the following conditions:
Installation must be in accordance with this report and the report holder’s published installation instructions. In the case of a conflict between the published installation instructions and this report, the more restrictive requirements govern.
Under the IBC, a report of geotechnical investigation must be submitted to the code official in accordance with IBC Section 1803, unless this requirement is waived by the code official as allowed by the Exception to IBC Section 1803.2. Under the IRC, the applicable soil bearing pressure shall be determined in accordance with IRC Section R401.4.
The Ever-Jacks are used to support wood posts for Type V construction under the IBC or any construction under the IRC.
For installations in under-floor spaces such as crawl spaces in compliance with the IBC and IRC, the bottom of interior footings are permitted to be installed at finished grade unless otherwise required by IBC Section 1809.5 or IRC Section R403.1.4.1 for frost protection or by IBC Section 1805.1.2 or IRC Section R408.6 for surface or ground-water. Installation of the Ever-Jack below finished grade is outside of the scope of this report.
The Ever-Jack may be installed directly on top of concrete foundational materials in crawl spaces provided the following:
- The concrete foundational materials must be designed for the applicable loads, including the load transferred from the Ever-Jack, subject to approval by the building official.
- Where the crawl space is subject to below freezing temperatures, concrete foundational materials must be protected from frost in accordance with IBC Section 1809.5 or IRC Section R403.1.4.1, subject to approval by the building official.
- Design and installation of concrete foundational materials are outside the scope of this report and are subject to approval by the building official.
The Ever-Jack must not be installed where subject to UV exposure.
The Ever-Jack must not be installed where subject to temperatures below -20⁰F (-29⁰C).
The design of the structure (including the wood post) supported by the Ever-Jacks is outside the scope of this report.
Design calculations in accordance with Chapter 18 of the IBC, Chapter 4 of the IRC must be submitted to the code official. The design must take into consideration the spacing of the Ever-Jacks.
