DTE Materials is the first domestic hempcrete block manufacturer. What’s unique about our process is that our hemp hurd aggregate is sourced entirely from CBD waste. By sourcing CBD waste, we are able to provide the most cost effective hemp hurd in the United States. We pass these savings onto you in our line of hempcrete blocks called Stonefiber. Materials come in prefabricated blocks of varying size for quick and easy installation in commercial and residential buildings. The blocks can be deployed as subfloor, roof, or wall insulation. They can also be used to form nonstructural partition walls.
