About Us

With 30 years’ experience in the construction industry, it became evident to founder Johan Tijssen from Hemp Block International  that the performance of building materials needed to improve.  Not only did he see it necessary to reduce the ongoing environmental impact by regulating temperature in a building, but also to reduce the carbon toll for production.

This carbon negative load bearing hempcrete block system is now available from Hemp Block International UK (HBI UK), a company built on the core foundations of innovation, integrity and sustainability.  As leaders in our field, HBI UK is a distributor of BIOSYS and MULTICHANVRE blocks, rebranded as HempBLOCK across the countries in which we operate.

HBI UK has one foot in meeting the construction industry’s immediate needs to minimise costs and increase efficiencies, and the other firmly in a more sustainable future within the construction industry. Together with our network of specialists, we supply a superior building block system and integrated architectural and engineering service to the British market.

Our Vision

The Hemp Block International UK vision is to play our part in a more sustainable construction industry. We do this by using carbon negative building materials to create a sustainable, healthy environment to protect our families and future generations.

This is why we choose hemp. Hemp provides us with seed for food, fibre for fabrics and composites, as well as the woody core (shiv) for building.

We firmly believe that all building projects need access to materials that reduce project time, lessen the impact on the environment, reduce building operation costs and lower ongoing carbon emissions into the future.
