Durability

Pensmore is particularly noteworthy for its exceptional structural integrity. A proprietary TransForm concrete shell is reinforced with a special blend of Helix steel fibers by PolyTorx, making it highly resistant to extreme disaster conditions—including tornados, earthquakes, and even blasts. We believe these structural features will find application in some of the most turbulent regions of the world, where builders face unique challenges.

TransForm: TransForm is the next generation of insulated concrete form (ICF) technology developed by TF Concrete Forming Systems. Its versatility enables a builder to take virtually any architectural design and implement it with superinsulated concrete, optimally placing the insulation to take maximum advantage of the thermal mass effect. While several ICF systems exist on the market, many have steep learning curves, result in warped or out of true walls, and are prone to “blowing out” unpredictably on the job site as the concrete is poured into the forms. TransForm’s patented design is simple for contractors to learn and use, and boasts new features that have virtually eliminated the “blow out” problem. Finally, the system is versatile enough to accommodate the complicated jogs and angles of Pensmore’s French chateau design. TransForm allows even the most sophisticated architectural styles to be molded out of reinforced superinsulated concrete.

Helix: As a building material, concrete is extremely resistant to compressive forces. Still, most concrete structures need to be reinforced with special bars, grids, plates, or fibers for added tensile strength—particularly in high-stress environments. Pensmore accomplishes this with Helix steel fibers by PolyTorx: a reinforcement technology originally developed at the University of Michigan for earthquake and blast resistance in situations where rebar would simply not be enough.

As concrete is stressed or bent, rebar and ordinary fibers begin to fail after frictional pull out. But Helix fibers feature a unique “twist” shape that increases the frictional resistance—much like trying to pull a corkscrew from a cork without untwisting it. More importantly, the “twist” shape changes the failure mechanism from friction to a torsional mode. The additional force required is so large that the result is a performance level never before possible. This makes our structure more resistant to extreme weather and disaster conditions, allowing its concrete walls to absorb shocks and bend with them instead of breaking away from the steel rebar that reinforces it.

Concrete is one of the strongest and most durable known building materials in the world. Many Roman concrete structures built over two thousand years ago are still standing. By applying state-of-the-art technology to an ancient building material, Pensmore takes concrete building to the next level.
