Hempcrete

Hempcrete for what types of applications?

With ProKalk limestone and IsoHemp hemp, the hempcrete allows you to insulate the walls of your house from the inside in two ways :

• poured into a wooden formwork

• applied directly on the wall : no visible joint, smooth finish (recommended only for professionals)

Hempcrete can also be used in addition to IsoHemp hemp blocks in specific applications if, for example, the walls to be insulated are not even. In this case, it is advisable to fill the gap between the existing wall and the new wall of hemp blocks with the correct amount of hempcrete.

How to make hempcrete ?

By combining IsoHemp hemp and ProKalk limestone, making hempcrete has never been easier. Simply mix the hemp and limestone with water in the proportions indicated in the table below depending on the desired application.

We recommend using a pan or a concrete mixer. First pour 80% of the required amount of water and ProKalk limestone into the machine. Wait a few minutes to see milt appear.

Then gradually pour in the necessary amount of hemp needed until a pasty mixture is obtained. Add the remaining 20% water and adjust if necessary.
Be careful not to spin the mixture too long to avoid the formation of small balls. Use hempcrete quickly. Repeat as many times as necessary.
