ReadyBlock Zero - Zero Carbon Concrete Blocks

Building a lower carbon future, block by block.

ReadyBlock Zero is the first zero-carbon concrete block designed to support you to achieve the net-zero homes roadmap. 

Manufactured to BS EN 771-3, the CarbonNeutral® block offers the same quality, compressive strength, and durability as traditional concrete blocks. The only difference is that it is produced using low carbon material technology saving up to 80% on CO2e, with the residual CO2 offset to provide a fully CarbonNeutral product in accordance with The Carbon Neutral Protocol.

ReadyBlock Zero is one of the many low carbon construction solutions within the CEMEX Vertua® brand forming part of our commitment to sustainable development.

Features and Benefits

  • First, fully zero-carbon concrete block to support you in your net-zero homes roadmap

  • Can be used for  internal and external applications

  • Allows use above and below the ground, where strength and durability are prime considerations

  • Excellent sound installation and air permeability properties

  • Inherent thermal mass acts as a heat store


Go Carbon Neutral

From the final buildings you construct to the materials you choose, and the supply chain you use; every step of the process contributes to building a lower-carbon future.

Benefits of switching to ReadyBlock Zero:


  • Indistinguishable from a traditional concrete block. The only difference is it embodies up to 80% less carbon, with the remaining carbon offset.

  • Concrete blocks are the most common structural component in the construction of UK homes, by switching to zero carbon blocks, ReadyBlock Zero presents a huge opportunity for housebuilders to make significant carbon reductions.

Future Proof Materials

Buildings are responsible for 39% of global energy-related carbon emissions; with 11% of this coming from embodied carbon caused by the supply and manufacturing process of materials and construction methods

The Government’s Future Homes Standard is an important move towards reducing embodied carbon – ensuring all new homes must produce 75-80% fewer carbon emissions by 2025 and committing to reducing net carbon emissions to zero by 2050.

ReadyBlock Zero provides a timely solution for housing developers to get ahead of the game and start considering materials that embody lower or zero carbon in a step to reduce the overall carbon footprint of the development.

Carbon Offsetting

ReadyBlock Zero contains low carbon material technology saving up to 80% eCO2 compared to a traditional concrete block. The residual CO2 is offset to provide a fully CarbonNeutral® product through a verified carbon offset programme.

What is Carbon Offsetting?

Carbon offsetting is the purchasing of carbon credits from projects that deliver immediate emission reductions through sustainable development and renewable energy projects to compensate for emissions made elsewhere.

ReadyBlock Zero, part of our Vertua family of low carbon and sustainable building solutions, is certified as a CarbonNeutral® product in accordance with The CarbonNeutral Protocol, the leading global framework for carbon neutrality.

This means we make sure that for every tonne of CO2 emitted by ReadyBlock Zero there is one tonne less in the atmosphere.
