Down to Earth Materials

STONEFIBER, INSULATING CONCRETE BLOCKS MADE FROM AGRICULTURE WASTE.

The United States' first scalable ag waste to construction materials company.

What’s unique about our process is that our aggregate is sourced entirely from agriculture and forestry waste. By sourcing waste, we are able to provide the most cost effective bioaggregates 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.
