CarbiCrete is shaking up the construction world with its new way of making concrete. Based in Montreal, the company created a process that removes cement—one of the most significant sources of greenhouse gas emissions—from concrete production. Instead, they use leftover materials from steel factories, like steel slag, and mix it with captured carbon dioxide to make strong, long-lasting concrete. This method cuts emissions by reducing the amount of CO2 produced in production, making their products better for the environment.
What CarbiCrete offers
CarbiCrete specializes in producing concrete masonry units (CMUs) that rival traditional cement-based blocks in strength and durability. Compared to standard cement-based CMUs, CarbiCrete’s products have up to 30% higher compressive strength and superior freeze/thaw resistance while maintaining the same water absorption properties. This means builders and developers can achieve the same, if not better, performance without the environmental impact of cement production.
CarbiCrete partners with concrete manufacturers to retrofit existing production lines, enabling them to produce CarbiCrete blocks using industrial waste and CO2. This setup makes it easier for companies to switch to greener building materials.
CarbiCrete product lineup

CarbiCrete offers different types of concrete products that are tough, reliable, and better for the environment. These products include:
- Concrete masonry units (CMUs): Strong blocks for both structural and non-structural building projects, performing better than cement-based blocks.
- Paving stones: Durable and attractive stones for outdoor spaces like walkways, patios, and driveways.
- Custom concrete solutions: CarbiCrete partners with manufacturers to design special concrete products for unique construction projects.
Building a greener future for construction
Cement production causes about 8% of the world’s greenhouse gas emissions. CarbiCrete’s new process helps solve this problem by offering a cleaner, reliable alternative. Their carbon-negative products help construction companies lower their environmental impact while still getting top-quality materials.
As demand for green building grows, CarbiCrete is ready to help the industry meet sustainability goals without sacrificing quality or strength. CarbiCrete’s cement-free concrete leads the way to a cleaner, greener future in construction, showing that smart ideas and caring for the planet can work together.
