We manufacture a wide range of sustainable building products. We use a range of different hemp sources.

  • We Grow our Own Hemp
  • We Import Chopped Hemp

By using our products for construction you are using a completely renewable crop-based material which absorb carbon dioxide (CO2) as they grow, providing an opportunity to capture and store CO2 in the fabric of buildings. Using the woody core of the hemp plant with a lime binder we make a biocomposite substance called Hempcrete. The Hempcrete can be cast or sprayed into the walls of newly built houses.
