Hemp: The Building Material For The Future?
The growth of cannabis and the surge of its products have been mind-blowing the past couple of
years. CBD product sales are skyrocketing and analysts say the sales racked up to $6.5 billion in
2020. Large-scale production of hemp which is legal is also increasing and more investors are
coming into the industry. This growth has allowed most manufacturers to focus mostly on the use
of hemp for cannabinoids while sidelining other uses. One of the uses that have been sidelined is
the use of hemp as a building material known as hempcrete.
This article will help you know all there is to know about hempcrete and why it is widely believed to
be the building material of the future.
A detailed analysis
Hemp is generally known by all because of the cannabinoids it produces. Sadly this has taken the
spotlight away from the other bene ts of hemp. The ber plant has di erent types of industrial
uses such as textiles, bio-plastics, a wood alternative, and a building material called hempcrete.
These uses of hemp see the ber plant in di erent industries aside from the medical and
recreational industries where the use of hemp is familiar.
The name “hempcrete” contrary to what you probably thought doesn’t have much to do with
concrete. It is a special material used for walls and insulation in buildings. The material is made by
mixing the inner woody core of the stalk known as hemp hurd with a natural lime-based binder
and water. Due to the nature of the material, it needs a proper structural framework before it can
be tted into buildings. It cannot also be used in situations where there is constant contact with
groundwater.
Hempcrete is by no means a new building material altogether. It has been used in Europe for
decades, however, it is just slowly making its way into the US market. In order to promote its
growth in the US, there is a need to harness the vast farmlands of cannabis already available.
Steps to promoting hempcrete

Education
For the growth of hempcrete particularly in the US, there is a need for proper education and
information. The building material is not one that most are conversant with which means they will
need to learn how to work with it. This will require more than books as considerable hands-on
experience will also be needed to foster quick understanding. There is also a need to facilitate the
training through state and local channels to ensure that all hands are on deck.
Infrastructure
The growth of cannabis has ensured that there is the availability of vast cannabis farmlands. Much
of the produce of these farmlands are directed towards the medicinal and recreational use of
cannabis. The hurd used to make hempcrete is 65 to 85% of the cannabis plant. The hurd is not
useful for extracting cannabinoids which is why it is mostly discarded or used for compost. With
the right type of processors on these farmlands, the farmers can easily convert this wasted hurd to
make hempcrete
Increased demand
One of the reasons why the growth of hempcrete has stalled is because there is no assurance of
demand by end-users. This is why it seems like most farmers are holding back on the opportunity
to maximize the product. With the assurance of more demand, farmers can direct more resources
into the processing of the materials needed for hempcrete.
Hempcrete is dubbed the building material of the future for a number of reasons.
Bene ts of hempcrete (https://cannabis.net/blog/news/hempcrete-mother-natures-way-of-
building-stronger-nontoxic-homes)
Resistant to pests and rot
One of the added advantages of hempcrete that makes it perfect for the future is its resistance.
Many building materials su er attract from di erent pests, mold, or mildew. In no time they lose
integrity and a ect the overall standard of the building. This advantage gives hempcrete an
advantage over other building materials tted into walls and insulations of buildings.
It is an excellent thermal insulator
Hempcrete is a good choice for walls in homes because it is an excellent thermal insulator. Houses
with hempcrete insulations spend less on cooling costs. This also depends on the type of climate
available in such places and building design. Hempcrete acts as a thermal envelope in the room
and covers all leakages that may pass through seams and layers. Hempcrete has all available
organic materials encapsulated which makes it hard to ignite making it resistant to re.
It is more bene cial to the environment

https://cannabis.net/blog/b2b/hemp-the-building-material-of-the-future 5/11
One of the major reasons why hempcrete has been identi ed as a bene cial material for the
future is its bene t to the environment. Climate change is a major topic on everyone’s mouths
right now and a building material that works well in di erent climates is bound to get attention.
Hempcrete is good for a wet climate and it handles humidity very well. It saturates easily and dries
out without molding.
Drawbacks of hempcrete
Expensive
One of the major reasons holding back the growth of hempcrete in the building industry is the fact
that it is expensive. This is primarily because very few people are actively involved in this aspect of
the industry in the US making production and supply channels harder. This is bound to change in
the nearest future as more people are seeing the bene ts of hempcrete.
It takes time
This is one of the reasons why education on how to handle hempcrete is important. With more
knowledge, the issue of time can easily be sorted. However, presently wet hempcrete takes a
considerable amount of time to cure which a ects productivity. The process is also very labor-
intensive. In the hands of inexperienced hands, the issue of time is not the only problem as the
integrity of the nal product cannot be assured.
Bottom line
The early signs for the use of hempcrete as the building material of the future are very good. With
the necessary steps being put in place, most of the present drawbacks can be solved. Once that is
done, hempcrete will be used for more buildings in the US and beyond.

Can You Get High from Cannabis Topicals and Lotions?
The level of psychoactivity possessed by a transdermal preparation is highly dependent on the level of THC present in it, unlike
cannabis topicals. Transdermal preparations get absorbed into the body and as such when taken it's possible to experience
