What do you think of, when you think of hemp? Some people think of the nutritious superfood, like hemp seeds (aka hemp hearts) or hemp oil. Some people mistakenly think of Marijuana, a psychoactive relative of hemp. But did you know that the hemp crop has over 50,000 known uses to date? One of the most surprising uses is a building material called Hempcrete!
Hempcrete is a mixture of hemp hurd (the inner woody core of the the hemp crop), lime and water. This process creates a building material that is superior to traditional building materials in nearly every way! It has a surprising number of applications from insulation to wall construction to flooring. Here are some of the surprising features of this new construction technology.
Efficiency Hempcrete is so insulating, self regulating and energy efficient that in many climates it eliminates the need for heating and air conditioning all together! This results in huge energy savings for the homeowner and the planet. These features also result in superior sound proofing both inside and out, giving you extra peace from the noisy world outside.
Durability The lifespan of Hempcrete is said to be measured in centuries rather than years or decades. In fact, humans have used it for most of modern history! Recently, an abutment on a still standing 6th century bridge in France was discovered to contain Hempcrete! It is also highly resistant to cracking when exposed to movement, making it an ideal building material for earthquake prone areas.
Highly Fire, Pest, Water, Rot and Mold Resistant Not only can hemp provide superior protection from fires, pests, rot, mold and water, but it can do it without the use of harsh chemicals. It also accomplishes these amazing feats while remaining breathable, creating a healthier environment for your family.

Sustainability The hemp crop grows to maturity in 90-110 days, and grows nicely in our short Canadian summers. When compared to the amount of time it takes to grow a tree to maturity, it’s easy to see which material is more sustainable. Hemp also removes 4x the CO2 from the atmosphere than trees, and continues to remove this toxin from the air after it is processed and installed! If the Hempcrete needs to be torn down for any reason, it can simply be tilled into the soil as fertilizer.
It’s easy to see the incredible potential of this product. It is more sustainable, durable and efficient than traditional building materials, and provides a safer, cleaner home for its tenants. Hempcrete is just another amazing way that the industrial hemp crop can build a more sustainable future for us all.
