Workshop Instructor: Chris Magwood
Come and discover how a simple mix of natural materials can create a remarkable thermal insulation!
Hempcrete (or hemp-lime) construction uses chopped hemp hurd (the woody core of the hemp plant) mixed with hydraulic lime to create an insulation material with excellent thermal, moisture-handling and structural properties.
In this workshop, participants will learn about the components of hempcrete, see a slideshow of various Canadian and international hempcrete building projects, and gain an understanding of how, why and where hempcrete is an appropriate material choice. In the classroom, we will look at the costs, sourcing and building science of using hempcrete on new building projects and renovations.
Test cylinders of mixes using hydraulic lime, hydrated lime, and hydrated lime plus metakaolin
In the hands-on component of the workshop, participants will learn how to assess the necessary materials and create a mix that is appropriate for a desired end use. We will use mixing machinery to create batches of hempcrete, and learn how to place them in a wall, floor and/or roof. Different types of framing and shuttering (or forming) systems will be shown, and every participant will leave with a hempcrete block they cast themselves.
After this workshop, you will be able to undertake a hempcrete project of your own!
