Bison BIND/R

Bison BIND/R is an innovative proprietary hempcrete binder that hardens within hours to integrate hemp insulation into your construction project efficiently and seamlessly. Crafted from sustainable materials, this product offers a unique combination of constructability and insulation potential, breathability, acoustic performance, and thermal mass, making it ideal for eco-conscious builders and homeowners.

BIND/R can be used much like any other hempcrete binder. To maintain an efficient construction workflow, the following process is recommended:

• Add 50 lbs of hemp hurd to the concrete mixer. We recommend a single-shaft paddle or mortar-type mixer with a capacity of nine (9) cubic feet or more.
• Add 50 lbs of water (six gallons) to the hurd to wet and cut down on dust. Mix for 30 seconds to one minute.
• Add 50 lbs of BIND/R (one bag) to the hurd and water mixture and mix for 30 seconds to one minute.
• Add 25 lbs of water (three gallons) to the BIND/R-hurd mixture and mix for 30 seconds to one minute.
• Place BIND/R hempcrete mix between the studs and tamp to ensure proper consolidation.

For estimating purposes, 50 lbs of builder’s grade hurd mixture will result in eight (8) cubic feet of BIND/R Hempcrete.
