In a groundbreaking move this August, a Euro-based hemp block company began its first US construction project in Wildwood, GA.<\/p>\n

HempBLOCK USA marked dual milestones by commencing its first build and hosting the first HempBLOCK Master Builder training program in the United States.<\/p>\n

As a fervent advocate for hemp in construction, I am proud to say I helped build the first wall of HempBLOCK USA\u2019s first project in the United States.<\/p>\n

The demand for HempBLOCK International\u2019s product has surged throughout the USA, founder Johan Tijssen told HempBuild Mag. Developers, hemp processors, Native American tribes, and affordable housing organizations have reached out to the company, Tijssen said.\u00a0<\/p>\n

The blocks are currently only manufactured in France. However, this should change soon.\u00a0<\/p>\n

Tijssen plans to meet with investors to set up three new manufacturing facilities in the USA. They aim to open the first factory within two years, contingent upon raising $8 million. They are considering potential factory locations in prominent hemp-cultivation states such as North Dakota, South Dakota, and Texas.\u00a0<\/p>\n

The Project: Keith and Katie Bien\u2019s Sustainable Dream<\/strong><\/h2>\n

Keith and Katie Bien<\/span><\/a> have developed a passion for sustainable building over the course of their marriage. They even took a permaculture design course during their honeymoon. As caretakers of Katie\u2019s multigenerational family farm, they were thrilled to acquire an adjacent lot for their sustainable hempcrete dream home.\u00a0<\/p>\n

After years of research, their decision was final: They would build with HempBLOCK USA\u2019s interlocking blocks.\u00a0<\/p>\n

Their determination compelled them to import the blocks, which took three weeks to ship, rather than await local availability. They even secured a conventional loan from a local bank, <\/span><\/a>setting a notable precedent.<\/p>\n

The Bien\u2019s two-story, 2600 square-foot home is nestled into a mountainside, featuring a walk-out basement that opens to a lush forest and a creek. All above-grade exterior walls and most of the interior walls are hemp blocks. The project only uses concrete for retaining walls and footings.\u00a0<\/p>\n

Steel fabricated locally by OS Fabrications, timber beams and lintels above doors\/windows, and bond beams around the top of the walls create the structure that HempBLOCK International engineers designed. The blocks come in four shapes, two of which feature holes for steel posts. A U-shape block accommodates lintels and the bond beams.\u00a0<\/p>\n

The Master Builder Class<\/strong><\/h2>\n

The students had to study the manual and pass a test before arriving at the site ready to work. The two-day training included floor preparation, block laying, and structural considerations, including the incorporation of a doorway. We installed steel posts and filled post holes and lintels with a perlite\/cement mixture.\u00a0<\/p>\n

While some noted that window installation was missing from the training, the two-day session was comprehensive.<\/p>\n

The Potential of HempBLOCK<\/h2>\n

These interlocking hemp blocks, crafted from hemp wood and a natural clay-rich lime binder, require no mortar.\u00a0<\/p>\n

They serve as formwork for the structure and adapt around steel frames and plumbing by cutting them in half with a chainsaw and rejoining using glue and screws. Simple scrapers allow for sculpting, and leftover scraps easily fill gaps.\u00a0<\/p>\n

Both interior and exterior sides receive a lime plaster render with embedded fiber mesh for cohesion, protection, and added insulation.\u00a0<\/p>\n

Though shipping costs from France to the USA can multiply the hemp block\u2019s price, the Biens have found that the overall expense remains competitive with traditional construction methods while offering a range of exceptional benefits, they said.<\/p>\n

The Block is 100% natural, sustainable, highly insulating, toxin-free, water permeable, fireproof, mold-proof, and pest-proof. Its durability increases over time as it petrifies, lasting centuries compared to the 50-100 years of conventional construction. Opting for lime over cement also reduces CO2 emissions by 80%, achieving a carbon-negative status through carbon sequestration.<\/p>\n

The block system replaces siding, vapor barriers, sheathing, studs, insulation, drywall, and paint. It is also a perfect alternative to concrete blocks.<\/p>\n

As Katie Bien noted, local production in the United States could shift HempBLOCK blocks from \u201ccomparable to conventional building\u201d to \u201cmore cost-effective than conventional building,\u201d thereby creating opportunities for affordable housing.<\/p>\n

HempBLOCK USA is leading the way to make this innovative product more accessible and affordable for everyone who wants to build a better future with hemp.\u00a0<\/p>\n
