Hempcrete or hemp-line will finally ‘officially’ be used as a building material in the construction of homes in the United States after years of unofficial use. Lots of builders favor the material due to its fire, pest, and mold-resisting characteristics and, of course, its sturdiness. That, accompanied by its carbon sequestering properties, make hemp-lime a very useful material to engineers and builders alike. However, it won’t be fully official till the 2024 implementation of appendix BA.
