Kellen Breccia is an exclusive, architecturally-refined concrete paver featuring a top layer of carefully-selected 100% stone aggregates free from sand and pigments, available in combination with CERO, which utilises geopolymer technology to deliver CO2 from just 7.3kg* per m2. It provides all the environmental benefits of replacing the core cement binding, but with no visible difference to the concrete block.

The top layer is produced in four grain sizes of aggregate, making it extremely durable and less prone to general fading. Its natural, water-etched appearance means Breccia is particularly suited to prestigious projects.

Available in combination with CERO

By replacing much of the cement with an alternative binding agent, carbon content in CERO options is reduced by 50% compared to standard Kellen, already a leading environmentally-friendly natural-stone-topped concrete.
