According to TechCrunch, Chilean startup Strong by Form has developed an engineered wood product that can replace concrete and steel in structural floors, achieving 10-meter spans while being lighter than conventional materials. The company, presenting at TechCrunch Disrupt 2025, uses a wavy panel design with internal cavities that resembles cross-laminated timber externally but features optimized wood flake alignment internally. This innovation represents a potential breakthrough for reducing construction’s significant carbon footprint, though several challenges remain.

Understanding the Carbon Problem in Construction
The construction industry faces mounting pressure to address its environmental impact, particularly what’s known as “embodied carbon” – the emissions generated during material manufacturing and construction before a building even becomes operational. Traditional building materials like concrete and steel are exceptionally carbon-intensive to produce, with cement production alone accounting for approximately 8% of global CO2 emissions. While engineered wood products like cross-laminated timber have emerged as lower-carbon alternatives, they’ve been limited by structural constraints that prevent wider adoption in larger commercial and residential buildings.
Critical Analysis of the Technology
While Strong by Form’s claims of achieving 10-meter spans are impressive, the technology faces several significant hurdles. The manufacturing process appears to require specialized equipment and proprietary software to achieve the precise wood flake alignment needed for structural integrity. This creates both scalability challenges and potential intellectual property protection issues. Additionally, the fire resistance claims need rigorous third-party verification, as building codes increasingly require demonstrated fire performance for structural materials. The company’s assertion of achieving price parity with concrete through structural optimization seems optimistic given the higher material costs typically associated with advanced wood products and the conservative nature of structural engineering practices.
Industry Impact and Market Potential
If Strong by Form can overcome these challenges, the technology could disrupt the $1 trillion global construction materials market. The ability to create hybrid buildings combining wood floors with steel or concrete frames represents a pragmatic approach to decarbonization that doesn’t require completely rethinking building design. The company’s parallel development of thin panels for train interiors demonstrates smart business strategy – using lower-risk applications to fund development of their core structural product. This approach could help them navigate the notoriously slow adoption cycles of the construction industry while building credibility with manufacturers and engineers.

Outlook and Predictions
The success of Strong by Form will depend heavily on their upcoming $10 million Series A round and subsequent pilot plant development. Even with sufficient funding, they face a 3-5 year timeline for meaningful commercial adoption, given the need for code approvals, engineering validation, and contractor education. The company’s participation in TechCrunch Disrupt suggests they’re pursuing the Silicon Valley playbook of rapid scaling, but construction materials typically require more measured growth. Realistically, we might see limited commercial deployment by 2027-2028, with broader adoption contingent on demonstrating long-term durability and securing partnerships with major construction firms. The technology shows genuine promise for reducing construction emissions, but the path to market will be longer and more capital-intensive than typical tech startups.
