THE INSULATED CONCRETE FORM THAT HELPS CORNER YOUR MARKET
Some of Our Industry Leading ICF Block Features
The Stronghold ICF Difference
No More Guesswork. No More Extra Steps. Just Strong, Reliable ICF.
If you’ve worked with ICF before, you know the drill—stacking goes quickly, but then come the hours spent adding extra strapping around corners and T-walls “just in case.” It’s time to stop worrying and start building with confidence.
Stronghold ICF is the first insulated concrete form system intentionally engineered to address blowouts right in the block design. We tackled the industry’s “elephant in the room” head-on—because we know it's been the #1 reason many contractors hesitate to fully embrace ICF.
Our unique design encapsulates the concrete in place, making the pour predictable, smooth, and stress-free. With Stronghold, building high-performance homes to LEED, Passive House, or Net Zero standards isn’t just possible—it’s routine.
Say goodbye to ICF hesitation. Say hello to Stronghold. Build with Confidence.
Engineered for Straight, Trouble-Free Walls—Every Time

- Integrated power strips on all corners provide unmatched strength and stability
