Frequently Asked Questions

Does the Hobbs Vertical ICF Wall System meet Canadian and American building codes?

Yes, by providing project engineering by a registered professional engineer, our system complies with building codes.

Do you have a CCMC or ICC Report?

No. Instead our distributors provide professional engineering on a project-by-project basis to comply with local and state/provincial codes. A professional engineer will prepare documents with calculations and important structural data for items, such as rebar size and placement locations, concrete strengths, and specifications. These calculations must be followed precisely during the assembly and installation of the Hobbs Vertical ICF Wall System. And, unlike typical ICF “blocks” which often times are left open to “interpretation” by the installer the Hobbs system is completely engineered on a project by project basis. This engineering provides the building official, contractor, sub-contractor and ultimately the project owner with “piece of mind” that the structure is built to exacting engineering standards.

How does the system work structurally if the form uses 40% less concrete and has a web thickness of only 2”?

The system has been developed using recognized engineering principles. Professional engineers have been involved in all aspects of the structural design from the very beginning of the design stage. Our system is a modified post-and-beam design that optimizes the use of concrete, and uses it only where it is structurally necessary. Flexural Strength Capacity testing by Iowa State University reports that the Hobbs Composite System has nearly 50% more structural value than concrete and rebar alone. The Hobbs VICF system is one of the only ICF products to ever have had such testing to prove strength.

How does the system use half of the labor of typical ICF block systems?

The system’s inherent design of being a vertical panel ICF means laborers work from the ground making it safer, faster, easier, and more user friendly while the system is installed primarily from the ground making it a safer wall system to install. There is no gluing, taping or tying the system unlike traditional ICF blocks.

How does your system achieve it’s R30 insulation value?

Where we don’t need concrete structurally, we use 39% more foam insulation than typical ICF blocks. And, keep in mind that our system doesn’t allow air exchange. No air is passed through the wall!

How is a floor system attached when using the system on all levels of a project?

We recommend either the Simpson-ICFVL connectors or Watkins Hangers that are compatible with the Hobbs Vertical ICF. The connectors are specifically designed for use in ICFs and are easily installed.

Do you recommend using your ICF system above grade?

The ideal application would definitely be above grade. Take full advantage of the excellent insulating properties of the system where the above grade walls are fully exposed to the elements of heat/cold and wind, and the disaster resistant superiority of reinforced concrete is ideal in hurricane and tornado prone areas.

What applications are suitable for use of the Hobbs Wall System?

The wall system is suitable for basements, slab-on-grade and above grade residential and commercial applications.


Is Hobbs ICF competitively priced with other ICF products or other wall systems?

Yes. The Hobbs Vertical ICF Wall System allows the user to save up to half the labor, uses less concrete with out sacrificing strength and expect between 50-70% savings in energy cost due to our high +R-30 insulation value. Our end product is at or less than the competition with all of these factors considered.
