This blog post highlights the technical performance, code compliance, and design flexibility of these two precast solutions. We also address frequently asked questions to streamline your decision-making process and reduce confusion at checkout or on the job site.
ICC-Certified Confidence
EZ-TUBE® Pier Footing System and EZ-PAD® (also known as Endurocrete Wheel) are both certified under ICC-ES Evaluation Report ESR-5035, verifying their compliance with:
- 2021 International Building Code® (IBC)
- 2021 International Residential Code® (IRC)
The certification under ICC-ES Evaluation Report ESR-5035 confirms the products’ adherence to the prescriptive and performance-based requirements of the 2021 International Building Code® (IBC) and the 2021 International Residential Code® (IRC). This third-party validation provides engineers, architects, and contractors with the assurance required for seamless integration into structural designs and successful permitting and inspection processes.
Load Performance and Structural Capacity
The structural integrity of EZ-TUBE and EZ-PAD systems is defined by their engineered capacity to withstand both gravity and uplift loads. Allowable capacities are meticulously quantified based on critical parameters, including soil bearing pressure and system configuration, as detailed in the following tables:
EZ-TUBE® Load Tables (With Base)
- Base bearing capacity up to 30,846 lbs with 4 tubes stacked on 12,000 psf (pounds per square inch) soil.
- Tension/uplift resistance of 340 lbs, consistent across soil types.
EZ-TUBE® Load Tables (Without Base)
- Up to 7,861 lbs bearing capacity with 2 stacked tubes on high-capacity soil.
- Tension/uplift resistance ranges from 60 to 240 lbs depending on configuration.
EZ-PAD® Load Tables
- Engineered to support up to 12,778 lbs in 12,000 psf soil conditions.
- Constant tension/uplift resistance of 60 lbs.
These capacities are derived from engineering analysis and testing as part of the ESR.
System Components and Compatibility
Precast Concrete Precision
- EZ-TUBE® Upper Sections are cast with precision from 5,000 psi (pounds per square inch) concrete, featuring an 11-inch diameter and 12-inch height, with a unit weight of 60 lbs TYP.
- EZ-TUBE® Base Sections are manufactured with 5,000 psi, with a 22″ diameter x 7.5″ tall, weighing 120 lbs TYP
- EZ-PAD®: The EZ-PAD® (Endurocrete Wheel) is manufactured from 5,000 psi high-strength concrete, presenting a 14-inch diameter and 6-inch height, with a nominal weight of 60 lbs.
Included Hardware
Each EZ-TUBE STACK (available in 2-STACK, 3-STACK, 4-STACK, and 5-STACK configurations) is supplied with integral connection hardware, including a galvanized ½-13 threaded rod, a corresponding ½-13 nut, and a 3″x3″x¼” washer. This comprehensive inclusion facilitates direct and expedited top-plate or anchorage point installation, eliminating the need for supplementary hardware procurement.
This allows for fast top-plate or anchor installation without sourcing additional hardware.
Post Base Installation
The EZ-TUBE system is designed for seamless integration with various post base configurations, including those accommodating 8×8 structural posts. Securement is achieved through the integrated threaded rod and washer assembly, ensuring a robust connection.
Flexible Bonding Options
While a 3,000 psi (minimum compressive strength) mortar is the specified bonding agent for stacked sections, a high-quality, below-grade-rated construction adhesive may be utilized as an alternative, contingent upon project specifications and adhesive manufacturer guidelines.
Frequently Asked Technical Questions
- Is it permissible to install pre-assembled EZ-TUBE stacks?
- Yes, however, pre-assembled stacks necessitate mortar bonding between sections and must achieve full cure strength prior to lifting and placement. Proper lifting methodologies, such as the use of a lifting sling, are imperative for safe handling and installation.
- What are the applicability and design considerations for utilizing EZ-TUBE in pier and beam foundation systems for residential or light commercial structures?
- EZ-TUBE is frequently used for pier and beam foundations, but consult a structural engineer to determine the number and placement required based on your soil and structural loads.
- Do EZ-TUBE STACKS include all necessary components for a complete installation?
- Yes. All necessary hardware for internal connection and top anchor interface is included.
- What depth considerations are paramount for EZ-TUBE installation?
- We recommend digging the hole slightly wider than the 22″ EZ-TUBE base to ensure leveling and compaction.
- How deep should I dig?
- Compliance with local frost line depth requirements is critical to mitigate the risk of frost heave. EZ-TUBE bases are engineered for installation below the documented frost level, in accordance with applicable building codes.
- Are customized EZ-TUBE configurations available beyond standard STACK offerings?
- Yes. For tailored configurations (specific numbers of bases or uppers), contact EZ-CRETE directly rather than ordering preconfigured kits online.
Made for Builders. Backed by Code.
EZ-TUBE and EZ-PAD represent meticulously engineered foundation solutions designed to optimize project efficiency without any compromise on structural integrity or regulatory compliance. The provision of pre-engineered capacity data, coupled with rapid installation protocols and robust ICC-ES certification, significantly de-risks the foundation phase, minimizing the common complexities and delays intrinsic to traditional cast-in-place concrete systems. For structural engineers, contractors, and architects, specifying EZ-TUBE or EZ-PAD ensures the deployment of a technically sound and code-compliant foundation, thereby establishing a robust underpinning for any construction project.
