PetraForm makes an engineered carbon additive that gives concrete the one property it has always lacked: tensile strength. At doses that price like an ordinary admixture.
Talk to the foundersConcrete is the most used material on earth — and it is roughly ten times weaker in tension than in compression. Cracking sets its service life. The workaround has always been steel.
Form-1 is a proprietary carbon material — an engineered metal–carbon composite produced in a single-step synthesis — that acts as internal reinforcement in cementitious materials. It doses like a conventional admixture, at 0.1–1% of cement weight.
Company laboratory results, cement paste, 2026. Gains attenuate in mortar and concrete; independent third-party verification in concrete is the company's current program. We hold every claim to what has been measured.
We start where tensile strength is the entire purchase.
Where a single load test qualifies a product, tensile gains translate to thinner walls from the same molds — or the same wall sold at a higher load class.
Flexural strength sets slab thickness. Real tensile gains mean thinner slabs, displaced mesh and fiber, and less placement labor.
3D-printed concrete has no rebar by design. Tensile strength and early-age crack control decide what printed structures can become.
Our industry qualifies materials through evidence, and we would not have it any other way.
Every claim we make traces to a measurement. What is measured today is stated with its limits. What is not yet measured is the program — independent, third-party, in real concrete.

If you produce pipe, precast, ready-mix, or printed concrete, we would genuinely like to learn how you evaluate new materials — and our 2027 trial program has a limited number of slots.
