Why Concria
We believe concrete floors should be finished at placement — not treated, coated, and maintained for decades after. Concria makes that possible.
Founded in Finland. Proven Worldwide.
Concria Oy was founded in Finland with a simple question: why does concrete flooring require so many products, so many return trips, and so many compromises?
After 15+ years of R&D, the answer became the patented Optimal Slab dry-shake hardener system — a fundamentally different approach that hardens, densifies, and cures concrete in a single visit during placement.
Today, Concria floors are installed across Europe, Asia, and now the United States. From data centers in Finland to supermarket distribution centers in the Netherlands, the technology is proven at scale.
Sika AG — 30% Strategic Stake
In 2023, Sika AG — the world's largest concrete admixture company — acquired a 30% strategic stake in Concria Oy. Sika evaluated hundreds of concrete technology companies globally and chose Concria.
This partnership provides Concria with access to Sika's global distribution network, R&D resources, and technical expertise. It also validates the Optimal Slab technology at the highest level of industry scrutiny.
When the world's largest concrete company invests in your technology, it says something.
