How Tall Can You Build with ICF?

At Rocktown ICF Supply, we often receive questions about potential limitations on wall heights when building with Insulated Concrete Forms. The simple answer, is that there are no inherent restrictions on how tall you can construct with ICFs! As long as the structure is braced and stabilized during the concrete pour, the sky’s the limit.

When constructing tall ICF walls—especially those exceeding 20 feet—proper bracing and consolidation become critical to maintaining structural integrity. For projects with intermediate flooring every 8 to 10 feet, construction is relatively straightforward: pour the walls, install flooring, and repeat. However, for uninterrupted tall walls, advanced bracing techniques and scaffolding systems such as buck scaffolding, turnbuckle bracing, or crank-up masonry scaffolding are essential to ensure stability. Every serious ICF contractor should know how to handle tall walls, and new technologies, including specialized bracing for walls up to 24 feet, make the process more efficient.
