Renewabuild Great Plains introduces North America's first patented structural hempcrete wall system — engineered for real-world building conditions, combining strength, performance, and sustainability.
Renewabuild Great Plains delivers a fully integrated, high-performance structural wall system designed for speed, strength, and long-term performance.
Each wall is built using patented modular blocks combined with a post-tensioning rod system, providing structural integrity and enhanced seismic resilience — revolutionizing how modern structures are built.
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.
Structural strength & seismic performance
Post-tensioned system designed for high structural loads, long spans, and seismic resilience in demanding environments.
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.
Performance
Built to outlast. Engineered to outperform.
2-Hour
Fire rating
No smoke. No flame spread. No hazardous fumes.
250 mph
Wind & impact
Post-tensioned. Hurricane and derecho winds rated.
R-28–R-40
Thermal performance
High thermal mass and a hemp-lime insulating core. No separate insulation needed, depending on assembly.
100 yr+
Design life
Strengthens with age. Locks carbon for life.
Acoustic
Reduces sound transmission between interior spaces and from exterior sources.
Breathable
Vapor-open walls regulate moisture without vapor barriers.
Durable
Resistant to rot, freeze-thaw cycling, UV exposure, and water damage.
Low waste
Reduced maintenance requirements and minimal construction waste.
R-28 to R-40 insulation. 100-year life. Wildfire and hurricane immunity. Architects who spec hempcrete in 2026 own the category before the competition catches up.
R-40 insulation (w/ lime coating)
100-year design life
Wildfire & hurricane proof

Carbon
Carbon-negative walls.*
Hemp sequesters carbon as it grows. Locked into a Renewabuild wall, that carbon stays put for the life of the building.
8–22 tonsCO₂ per hectare, per season
* Carbon negative based on a 2017 study that will be updated in early 2027 specific to the Rock Valley, IA plant.
