We are proud to combine our internally developed innovations with external collaborations, supporting and advancing the future of eco-friendly concrete technologies together.
GreenCem is extensively used across many SigmaRoc product ranges in the UK, demonstrating our commitment to integrating sustainable practices within our own operations. This widespread internal application underscores the reliability and effectiveness of our innovative concrete product solutions.
For many, the resistance to going green in concrete has been the cost and the ability to deliver. With GreenCem, we have removed these barriers. While others talk of lowering their carbon footprint, we’re delivering projects.


A range of bespoke accelerators that aid with the cement replacement in concrete of up to 95%. GreenCem offers a more cost-effective solution whilst still providing similar carbon reduction benefits to cement-free (up to 80% reductions). Favoured in applications where compliance to standards maybe necessary or desired. Furthermore, GreenCem solutions incur little to no additional costs, both in terms of mix design and infrastructure, eliminating upfront investment barriers and facilitating the transition to economically viable, low-carbon concrete.


Cemfree is a patented, award-winning alkali-activated cementitious material (AACM).
Cemfree was created in 2011 to tackle construction’s biggest climate challenges. We’ve partnered with academia and industry to develop and deploy advanced ultra-low carbon concrete technologies.
Years of development have produced an industry-leading, acid-resistant solution that’s whiter than white cement. Rigorous PAS8820-standard testing proves its strength can go toe-to-toe with traditional concrete.


Through 2023 GreenBloc technology has made significant strides in sustainable development across the business, offering up to 50% carbon reduction on all standard blocks produced at CCP Building Products.
This has saved over 6,000 tonnes of CO2 since its introduction, and has been offered at no additional cost to the customer. CCP completed its expanded new ranges by introducing an additional premium range product, which sits between its standard 50% reduction product and ultra cement-free, and provides up to a 70% carbon reduction at a competitive price.
