Woodflow-core

Reinventing the core of construction

Woodflow-core redefines structural slabs by introducing a lightweight alternative to reinforced concrete for long spans and high-rise buildings. It enables a new generation of highly efficient, cost-competitive structural systems that improve  productivity across the construction process.

structural spans.

The next standard in structural performance

Woodflow-core is a prefabricated structural system designed for long span requirements.

It delivers the same load-bearing capacity as reinforced concrete at a fraction of the weight, time, and CO2 emissions.

Creating value along the entire chain

Woodflow-core combines factory precision with site efficiency, cutting installation time, reducing project risk, and enabling scalable carbon compliance.

High-performance by design

Woodflow-core leverages structural integrity and resource efficiency in one system.

01

Unprecedented value

Woodflow-core is the first ever timber-based structural system that competes at cost with reinforced concrete solutions at scale.

02

Structural timber from low-grade wood

Stranding is the most efficient way to transform a tree into a structural element. Our strand-based formulation enables the use of low-grade wood, reducing material use by up to 75% compared to traditional timber while delivering components at a fraction of the cost of sawn wood.

03

Access an 80x larger market

Mass timber manufacturers can now access a market 80x larger than their current one - for the first time competing with concrete on price while increasing their margins by 50%.

04

Green construction without additional costs

Builders can now move toward prefabrication and green construction without additional costs. For the first time, they get beautiful, sustainable buildings that tenants value more than concrete at a lower cost.

05

Bringing biodiversity to forest plantations

By being largely agnostic to wood species, Woodflow-core creates value from underutilized trees, enabling forest owners to monetize a broader mix of species and reduce the risks associated with monoculture.

06

Decarbonize construction globally

By working with the mass timber industry as a whole, we can scale rapidly at a global level. Whether as a joint-venture or assembly partner, we collaborate to enable meaningful change at scale—empowering the industry to take wood to the next level.

Performance that speaks for itself

Faster projects. Lighter foundations. Lower carbon. Same strength.
