Lock-Block Ltd. annually processes 150,000 tonnes of concrete rubble from construction sites into high-quality aggregates suitable for making fresh concrete. That's thousands of tonnes diverted annually from landfill sites, and made into usable products that we sell under the Green-Stone™ brand.

Our mortar dust residuals are perfect for growing grass.
