Hempcrete & construction
Where do you source hempcrete materials?
Direct answer
Source graded hemp hurd (or pre-mixed kits/blocks) and compatible lime binders from construction-material suppliers, hemp processors with hurd lines, or importers — verifying moisture, particle size, and license paperwork. Proximity to decortication beats nominally cheaper distant hurd.
What to procure
- Hurd / shiv — construction grade, not bedding fines.
- Lime binder — matched to your system (hydrated, hydraulic, or proprietary).
- Pre-cured blocks — faster walls, higher unit cost, mortar compatibility required.
- Accessories — shuttering, breathable renders, structural connectors per engineer.
Spec questions suppliers should answer in writing
- Moisture content and max allowable at delivery
- Particle size distribution and dust percentage
- State hemp license / chain-of-custody for stalk origin
- Recommended mix ratio and wet density target
- Test data: thermal conductivity, compressive strength, fire class if available
