The Fox Block Interlock
When the Fox Blocks interlock was designed our Engineering staff made the choice not to focus on being within 1÷2” to 1” from the building dimension but to give the strongest interlock possible.
New Training for the Fox Block Interlock
We have found it to be a waste of time and energy to attempt to offset or stagger the block as in the photo to the left. By creating a vertical stacked seam you will be more accurate with the job dimensions and will increase your profit by gaining efficiency.
Remove Costs on your ICF Project
Two proven areas to remove costs are corners and truss wire.
How Strong is the Fox Blocks 90° Corner?
We built a test wall 440 feet long x 9′-4″ tall with 24 turns, with no bracing or strapping, to test the 90 degree blocks with concrete.
Attaching Floor Joists to Your Insulated Concrete Forms
Just one way to attach your floor system to the side of a Fox Blocks wall when building with Insulated Concrete Forms for multiple stories of construction.

Insulated Concrete Form Installation Checklist
Checklists can be an important part of any project. We’ve created a series of installation checklists broken out in phases to help you be the most efficient with your next ICF project.

How to Attach Heavy Stone Veneers to ICF Blocks
Masonry foreman, Carl from Casciani Masonry, explains the process and outcome of attaching heavy stone veneers to insulated concrete forms with Hohman Bernard 2‑Seal Concrete Ties, also referred to as “cow bells”.

5 Net Zero Energy Homes That Will Inspire
We’ve compiled a list of zero-energy homes that incorporate sustainable construction into the building process. The results are 5 facilities that prove zero net energy can be achieved with careful planning and appropriate implementation.
