KrunerRoc’s unique manufacturing process uses 60% less energy and emits 80%–90% less CO2 than cement concrete production.

100% recyclable.

100% of used KrunerRoc material can be granulated and fused for reuse, supporting a circular economy.

Expanded, widely available sand resources
Besides coarse-grained sand, all grades of sand can be used as aggregates for KrunerRoc. This includes desert sand and mining waste sand, considered too rounded or too fine for concrete use. These sands are untapped and available in vast quantities in every continent.
