Atlantic Canada’s first hempcrete building to be built in Tatamagouche


The first hempcrete building in Atlantic Canada will be constructed this summer at the DorjeDenma Ling program centre near Tatamagouche, Nova Scotia, reports Daily Business Buzz.

“Hemp-lime masonry, or ‘hempcrete‘, is a cutting-edge natural building material,”DorjeDenma Ling Sustainability Manager Dominic Watson Wall explains. “It is attractive, has great thermal and acoustic insulation properties and is carbon-negative, with no toxic elements, while being affordable and extraordinarily simple to build with.”

Wall says hempcrete”can be used to build walls or as an in-fill for roofs, floors or as a plaster. It uses industrial hemp, a crop already widely grown in Canada and renowned as fiber, food, and biomass.”

Hempcrete is a bio-composite made up of the hemp plant’s woody inner core (shive or shiv) and a lime-based binder.

There is high silica content in the shive, according to American Lime Technology (ALT). Its website says hempcrete is “a lightweight cementitious insulating material weighing about a seventh or an eighth of the weight of concrete.”

ALT’s website also notes that weather conditions at the jobsite can effect drying so the company has a factory that can dry hempcrete panels off-site.
