Hempcrete Binder


Proprietary, Made in USA Hempcrete Binder. Can be mixed with hemp hurd to make hempcrete (hemp-lime) walls, floors, blocks, and more. You can also mix this binder with sand to make mortar that is compatible with hempcrete. Or, cooler still, you can make insulating “hempy mortar” to reduce cold-bridging in mortar joints.

This hempcrete binder is designated for above-grade, non-structural construction, such as described in the Residential Building Code entry for hempcrete (hemp-lime).

Packaged in 50 lb., multi-wall paper bag with stitched closure and easy opening.

These unique hempcrete mixes are based in part on the most magnificent, long-standing structures of human history. Notably, the Roman Pantheon, still standing proud after nearly 2,000 years. The Pantheon is a marvel of engineering, as the worlds largest unreinforced (e.g. no “steel rebar”) concrete dome, at 142 feet in diameter. And the foundation of Roman concrete, was the combination of volcanic ash pozzolan and powdered limestone.

The Roman Pantheon is a magnificent example of “masonry done right.”
