Estimated materials

Enter your wall dimensions above and the material list will appear here.

Planning estimate only (±15–20%), based on typical published hempcrete wall mixes (~100 kg hurd, ~150 kg lime binder, ~300 L water per m³ placed) with a 10% waste factor. Not engineering quantities — confirm with your installer, binder manufacturer, and engineer before ordering.

Before you order

Check the hemp laws and licensing for your state (each state page lists who regulates hemp growers and processors, with the official links), browse the hempcrete, insulation and panel categories the marketplace carries, and find hempcrete builders and developers in the services directory. The hemp education hub has the basics.
