In 2024, Cemfree was acquired by SigmaRoc, where we immediately sought to enhance and develop our technology offerings by considering our manufacturing requirements across ready-mix and precast applications. This resulted in a more versatile range of technologies that can integrate into various manufacturing infrastructures and do not solely rely on cement-free technology but also consider other constraints and applications where there is a need to enhance the performance of low-cement content products.
