How is Isobloc Zero made?
Isobloc Zero blocks are manufactured at our Canadian facility using Carbicrete concrete. Carbicrete concrete is made with standard aggregates such as sand and gravel, but the cement typically used in conventional concrete blocks is replaced with steel industry by-products, such as steel slag. The mix is then activated using an alkaline binder.
During the manufacturing process, this composition chemically absorbs CO₂, forming solid carbonates. The result is a stronger concrete block made through circular economy principles that captures carbon during its production.
Why was Isobloc Zero created?
Reduced carbon emissions
Cement alone accounts for 7 to 8% of global CO₂ emissions. It is typically produced in centralized plants and delivered to construction sites by concrete mixer trucks, resulting in high fossil fuel consumption and tight pouring schedules.
Isobloc Zero is manufactured in a controlled factory environment and delivered directly to your job site. Using Carbicrete technology, our blocks are stronger and capture carbon during production.
Active contribution to the circular economy
Made from standard aggregates and steel mill by-products, Isobloc Zero gives a second life to industrial by-products.
Each square metre built with Isobloc Zero diverts approximately 43.75 kg of steel slag from landfill.
Reduced energy losses
Our concrete blocks can reduce energy losses by up to 50%, significantly lowering building energy costs.
Thanks to its continuous Type 22 expanded polystyrene core with no thermal bridges, the exterior concrete layer does not come into contact with the interior layer. This creates exceptional thermal mass, allowing stored heat and cooling to be released gradually into the building.
Same installation process
Isobloc Zero is installed the same way as our standard Isobloc blocks. No change in method is required on site.
What does Isobloc Zero change?
Reduces building energy costs by up to 67%
