Ultra-low carbon blocks with up to 80% lower eCO2**

At our current rate of material consumption, we’re absorbing 157% of the natural resources on the planet – meaning we’d need an Earth and a half to maintain our ecological footprint. As a building material, cement cannot be matched. But as the worlds third highest source of man-made CO2, something has to change!

Switching to Greenbloc for your build means offsetting the electricity emissions (and a bit more) for an entire year.*

Reduced resource deletion by substituting cement with an industrial by-product. Strengths achieved comparable to conventional concrete**.
