Relentless How Land Raising Works | Laurence Allen, Terranova
Dec 11, 2025
Laurence Allen, Co-founder and CEO of Terranova, dives into revolutionary underground wood-chip slurry technology aimed at raising land while mitigating flooding. He explains how his background at SpaceX shapes the company's efficiency and innovation. Laurence discusses the political hurdles in securing funding for resilience projects, the remarkable advantages of using wood chips, and how AI helps model geological conditions. With a focus on scalability and real-time construction, he highlights the potential for transforming cities like Miami using waste wood.

Episode notes
Left SpaceX To Bootstrap Long Stealth Phase
- Laurence left a SpaceX return offer to join the startup after his team dispersed, choosing the hard path of a slow, capital-efficient build.
- He reflects that long stealth and bootstrapping yielded patents and tech but sometimes regrets not raising earlier.
Wood Chips Replace Expensive Cement Grouts
- Cement grouting can lift land but is prohibitively expensive at scale; Venice tests proved feasibility but not cost-effectiveness.
- Wood chips solve volumetric material scarcity and cost, enabling scalable underground uplift.
Subsurface Wood Forms Strong, Stable Fill
- Wood-chip slurry compacts anaerobically into an MDF-like mass, offering stable load-bearing behavior and earthquake resilience.
- Subsurface wood can outperform unconsolidated alluvial soils for building support.
