RocBloc is a natural stone building block that creates a distinctive finished appearance as it is installed.
Its larger, consistent dimensions allow walls to be built faster, while the natural variation of the stone gives every project its own unique character.
Low carbon, durable and ready to be seen, RocBloc brings the structure and the finish together in one product.
RocBloc combines the natural strength and durability of limestone with a significantly lower-carbon way to build.
Precision-cut for modern construction, it delivers dependable structural performance without the energy-intensive manufacturing and chemical processing associated with materials such as concrete and clay brick.
Lower carbon by nature
RocBloc has a carbon footprint 55% to 86% lower than traditional clay bricks.s.
Built for structural performance
With strength options of up to 42kN, RocBloc provides the performance needed for demanding construction applications.
Minimal processing
Natural limestone requires far less energy to produce than heavily manufactured building materials.
Made to last
Stone is naturally durable and can be reused or repurposed, supporting a more circular approach to construction.
RocBloc offers a lower-carbon alternative to traditional masonry, without compromising on strength, durability or appearance.
Explore the data behind RocBloc, understand how its carbon impact compares with conventional building materials and discover why natural stone is a better choice for the future of construction.
