The Product
A Wall system THAT DOES MORE.
A fully integrated, high-performance structural wall system designed for speed, strength, and long-term performance.
The Renewabuild Wall System is constructed using modular blocks combined with a patented tensioning rod system, providing structural integrity and enhanced seismic resilience—revolutionizing how modern structures are built.
Starter strips ensure precise base alignment, while top-of-wall strips lock the system into a continuous structural assembly. A proprietary mineral-based mortar reduces thermal bridging while delivering strong bonding performance, eliminating the need for chemical adhesives.
Interior and exterior surfaces can be finished with breathable plasters, stuccos, or natural coatings, eliminating the need for traditional insulation or drywall due to the system’s thermal, acoustic, and moisture-regulating properties.
The result is a durable, breathable, and energy-efficient wall system that simplifies construction while exceeding modern performance standards.
HOW IT WORKS
Simplicity by Design: One Integrated Wall System That DOES IT ALL.
01
POLYMER COMPOSITE FRAME
An internal structural frame provides global wall strength, delivering high resistance to tension, compression, bending, and torsion. It serves as the structural backbone of every block.
02
HEMP-LIME SYSTEM
Premium, clean, size-specified hemp hurd and a proprietary mineral-based mortar fill the frame, delivering R40+ insulation, natural fire resistance, zero VOC emissions, and active carbon sequestration from day one.
POLYMER COMPOSITE FRAME CONNECTORS SITTING IN THE CURED HEMP/LIME MIX
Validated through independent testing with Intertek, Exova, SMT Research, and the University of Alberta.

WALL SYSTEM
ENGINEERED TO CONNECT.
The wall system is designed to perform at every junction, including corners, multi-story floor connections, and long-span walls. Cold-pressed steel starter and top plates, along with an integrated floor joist hanging system, enable continuous hempcrete exterior walls across multi-story construction.
CORNER ASSEMBLY
Blocks interlock at corner conditions, with a polymer composite frame ensuring continuous structural load transfer across all wall system junctions.
FLOOR JOIST CONNECTION
An integrated floor joist hanging system supports multi-story construction while preserving a continuous hempcrete exterior wall, eliminating thermal bridges and structural interruptions.
The Performance
Built for Every Condition.
From extreme cold to hurricane-force winds, wildfire, seismic activity, and beyond — our wall systems don’t just meet the standard. They make conventional materials look obsolete.
SOUND DAMPENING
Reduces sound transmission between interior spaces and from exterior sources for improved occupant comfort.
HEALTHY & BREATHABLE
Mineral-based, low-VOC system supports clean indoor air quality and healthy environments while regulating moisture naturally through a vapor-open design, eliminating the need for vapor barriers in most assemblies.
THERMAL EFFICIENCY
High thermal mass and insulating properties stabilize indoor temperatures year-round. Depending on assembly configuration, in-situ R-values range from approximately R25–R40. Eliminates the need for conventional insulation and drywall in many applications.
BULLET RESISTANT
Dense composite structure provides superior impact resistance, including ballistics testing — used in high-security builds.
DURABLE & LOW WASTE
Less than 1% construction site waste and up to 70% less lumber use compared to stick-frame construction. Resistant to rot, freeze-thaw cycling, UV exposure, and water damage—designed for long service life with reduced maintenance requirements.
CARBON REDUCING
Hemp-based components sequester carbon during growth, locking it into the structure for the life of the building and reducing embodied carbon.
