Hempcrete

A carbon-negative, breathable, fire-resistant bio-composite for healthy, high-performance walls.

Hempcrete is a bio-composite made from the woody core of the hemp plant (the "hurd"), a lime-based binder, and water. Cast or sprayed around a structural frame, it forms walls that insulate, regulate humidity, and resist fire — while storing carbon.

How it works

Hempcrete is an infill, not a load-bearing material. A frame carries the structure; the hempcrete does the work of insulation, air-sealing, and thermal mass. That pairing — regenerative infill plus a recyclable frame — is the foundation of our system.

Why it matters

  • Carbon-negative: hemp absorbs CO₂ as it grows; lime reabsorbs carbon as it cures.
  • Healthy & breathable: vapor-open walls manage moisture and improve indoor air quality.
  • Fire & pest resistant: the lime binder naturally resists fire, mold, and rodents.
  • Quiet & comfortable: excellent acoustics and stable interior temperatures.

The honest trade-offs

Hempcrete has lower compressive strength than concrete, so it needs a frame, and it depends on skilled labor and a mature supply of construction-grade hurd. Building that domestic supply chain and trained workforce is exactly where our venture focuses.
