Welcome to Hemp and Block

Established in Colorado in 2018, we are proud to be the first American hempcrete block company!

We strongly believe in supporting the American hemp farmers, processors, builders, all the great people who are doing so much to grow the U.S. hemp building industry. Our founding principle is to source all production materials from within the U.S., such as industrial hemp hurd, hydrated lime and natural pozzolan. Hemp and Block was the first company dedicated to producing MADE IN USA hemp blocks and we remain committed to building the U.S. supply chain!

Mission Statement

Hemp and Block’s mission is to use hemp to create natural, high performance building materials for making healthy, sustainable homes and buildings that last for centuries.



New facility!

We are excited to announce a major facility upgrade for our factory and offices. The new location offers a huge floorspace for indoor block curing racks, fabrication, massive amount of exterior space for material storage and mixing operations, and plenty of infrastructure and power to run block machines and more!

What’s more, this commercial space offers room to grow. We are in the design stages of several big projects that involve pre-fabricating and pre-casting hemp-lime homes at a massive, nationwide scale. Stay tuned!
