Wall System
The Product
An Engineered 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.
POLYMER COMPOSITE FRAME CONNECTORS SITTING IN THE CURED HEMP/LIME MIX
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.
03
POST-TENSIONING ROD SYSTEM
Post-tensioning rods are routed through the blocks in eight-foot spans, connecting the top plate to the foundation. This continuous tensioning system locks the wall assembly together under load, providing exceptional resistance to compression, bending, and lateral forces — including seismic and hurricane-force winds up to 295 mph.
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 — designed for long service life with reduced maintenance requirements.
SOUND
DAMPENING
Reduces sound transmission between interior spaces and from exterior sources for improved occupant comfort.
NON TOXIC &
LOW EMISSIONS
Made from mineral-based and natural materials with zero VOC emissions. Supports clean indoor air quality and vapor-open building design.
STRUCTURAL STRENGTH
Post-tensioned system designed for high structural loads, long spans, and seismic resilience in demanding environments.
BREATHABLE
Vapor-open system regulates moisture without vapor barriers, supporting healthier indoor environments.
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.
CARBON
REDUCING
Hemp-based components sequester carbon during growth, locking it into the structure for the life of the building and reducing embodied carbon.
PERFORMANCE PROPERTIES
EVERYTHING A WALL SHOULD BE And MORE.
This wall system doesn’t just replace conventional wall materials — it makes them obsolete. Every property is independently tested.
FIRE RESISTANT
Built to meet rigorous fire endurance standards, including a 2-hour fire rating under load (ULC S101). Zero flame spread and zero smoke development. Non-combustible per ULC S135-04.
MOLD, MICROBE & PEST RESISTANT
Naturally resistant to pests, mold, mildew, and microbial growth due to a high-pH mineral composition, vapor permeability, and lack of organic food sources.
THERMAL EFFICIENCY
WIND & IMPACT RESISTANCE
Engineered for extreme environmental conditions, including hurricane-level wind loads, seismic activity, and high-impact performance. The post-tensioned system enables tall wall assemblies and long structural spans, with performance tested up to 250 mph wind resistance at 20 ft and 125 mph at 30 ft configurations.
