Building blocks: 13 visionary companies making new construction materials

As the construction industry faces mounting pressure to reduce its environmental impact, a wave of Canadian manufacturers is stepping up with innovative, sustainable building materials. From carbon-negative concrete alternatives to hemp-based insulation and self-healing infrastructure, these companies are reshaping how we build—and what we build with. Here are some of the trailblazers leading the charge toward greener, smarter construction solutions.

Hemp Block Canada

Hemp Block Canada offers the nation’s only interlocking, load-bearing hempcrete block system. Made from hemp, lime, and water, these blocks are carbon-negative, fire-resistant, and provide excellent thermal and acoustic insulation. They can reduce construction time by up to 60% and are suitable for various building types, including homes, schools, and offices.

AtlantisFiber

Developed in collaboration with the University of British Columbia, AtlantisFiber’s self-healing concrete incorporates specialized fibers that intercept cracks, acting like internal band-aids. This technology enhances durability, reduces maintenance costs, and is being piloted in projects like the Chawathil First Nation’s parking lot and approach road.

CarbonCure

Halifax-based CarbonCure Technologies has pioneered a method to inject captured CO₂ into concrete during mixing, where it becomes permanently embedded. This process not only strengthens the concrete but also significantly reduces its carbon footprint. Their technology has been utilized in major projects, including Amazon’s HQ2 and General Motors’ manufacturing plant. Wikipedia

NForce-Fiber

NForce-Fiber is the world’s only ASTM/CSA-compliant hemp reinforcement fiber for concrete. It chemically bonds with the concrete matrix, enhancing strength and reducing plastic shrinkage cracking. Used in over 100 commercial projects, including the 2022 Beijing Olympics, it’s a sustainable alternative to synthetic fibers.

Hempcrete

Hempcrete specializes in hempcrete construction, offering services from consultation to contracting. They have developed hempcrete blocks compatible with standard North American framing and have been instrumental in projects like Alberta’s first code-inspected commercial hempcrete building.

Giatec Scientific

Ottawa-based Giatec Scientific Inc. is a technology leader in smart concrete solutions, with a strong focus on self-healing technologies. Their flagship product, Smart Concrete, incorporates advanced sensors and healing agents that activate when cracks appear, enabling both real-time structural monitoring and automatic self-repair. This approach significantly improves the durability and lifespan of concrete structures while delivering valuable data for proactive maintenance. Giatec’s commitment to innovation and sustainability positions its self-healing concrete solutions at the forefront of addressing the demands of modern construction.

Pultrall

Pultrall Inc., based in Thetford Mines, Quebec, is a leading manufacturer of composite materials for the construction industry, specializing in fiberglass and carbon-fibre reinforced polymer (CFRP) rebar under the V-ROD brand. In collaboration with Canadian researchers, Pultrall has played a key role in advancing corrosion-resistant, high-strength reinforcement for concrete structures, including bridges and parking garages. Their partnership with the University of Waterloo led to the integration of the FiberLoc anchoring system, enabling wider use of CFRP tendons in pre-stressed concrete.

Battle Lake Design Group

Battle Lake Design Group is an Edmonton-based design firm renowned in Western Canada for its expertise in straw bale building design and construction, alongside other sustainable materials. The firm has modernized straw bale techniques for both rural and urban applications, adapting them to the region’s challenging climate and integrating them with conventional building systems. Their approach emphasizes energy efficiency, durability, and moisture protection, earning recognition for advancing sustainable, climate-appropriate architecture in Alberta and British Columbia.

HempWorks Canada

Located in Kelowna, BC, HempWorks Canada supplies construction-grade hemp hurd, binders, hemp batts, flooring, and lumber. They also offer rental equipment and consulting services, supporting projects from conception to completion.

Northstar Clean Technologies

Northstar Clean Technologies Inc. is a Canadian clean technology company specializing in the sustainable recovery and reprocessing of asphalt shingles, with headquarters in Vancouver and commercial operations in Calgary. Founded in 2015, Northstar has developed a proprietary process that extracts liquid asphalt, aggregate, and fiber from discarded or defective asphalt shingles-materials that would otherwise end up in landfills-and repurposes them for use in new hot mix asphalt, construction products, and other industrial applications. 

Asinikahtamwak

Asinikahtamwak is an Indigenous-owned company based in Elk Point, Alberta, producing environmentally sustainable bio-fibre concrete blocks made from cement, water, and natural fibres such as hemp. Their blocks are lightweight, mold- and fire-resistant, and designed to provide durable, affordable housing solutions that support the vision of “seven-generation homes.” Operating from a 13,000-square-foot facility, Asinikahtamwak aims to scale production from 250 blocks per day to 1,000, using locally sourced natural fibres and waste materials.

University of Manitoba

A research team at the University of Manitoba, led by Professor Mercedes Garcia-Holguera, is pioneering the use of mycelium-the root-like structures of fungi-as a sustainable alternative to traditional building materials. By growing mycelium in agricultural waste substrates, the team produces biodegradable bricks and insulation panels, aiming to address supply challenges in remote and Indigenous communities. Their research focuses on testing mycelium’s resilience to harsh Canadian winters and scaling the technology for practical, environmentally responsible construction applications.
