Kellen CERO paving utilises geopolymer technology to deliver CO2 from just 7.3kg per m2.

By replacing much of the cement with an alternative binding agent, carbon content in CERO is reduced by 50% compared to standard Kellen natural stone topped concrete. Kellen CERO retains its aesthetic beauty whilst reducing its carbon footprint and prioritising sustainability.

Range

A complete palette of sizes, colours and finishes is available, with 60 plan sizes, 4 thicknesses, and over 100 colours across the range.

Low carbon

With a UK average of 30-34kg CO2/m2 for 80mm thick concrete paving, the need to switch to Lavaro CERO, with a range of 9.4-13kg, is clear.

This leading carbon figure, based on 80mm-thick Lavaro products, is achieved by replacing the cement traditionally used in the paving base.

By using geopolymer technology, which replaces cement as the binding agent in production, CERO can reduce CO2 emissions by up to 70% over normal cement products. CERO is also BS EN 1338 and 1339 compliant.
