Sustainability is a key priority for GD Harries and with the UK Government’s pledge to reach net zero carbon emissions by 2050, we are committed to playing our part in achieving this by supplying our customers with low carbon ready-mix concrete.

Concrete is a highly valued building product and, as the most used material on the planet, it also contributes a significant amount of CO2 to the atmosphere, with most of its carbon emissions resulting from one of its main components, cement.

As a major supplier of ready-mix concrete products in South Wales, we  have addressed this issue by using Greenbloc technology, which reduces the percentage of Portland cement clinker in our ready-mix concretes and uses ground granulated blast-furnace slag (GGBS), which has a significant effect on lowering the embodied carbon.

Greenbloc has been developed by companies within SigmaRoc, with a focus on finding alternatives to Ordinary Portland Cement (OPC) to reduce the carbon footprint of cement. The group provides low and ultra-low carbon concrete solutions across a range of precast and ready-mix concrete businesses.


GD Harries Greenbloc Standard Ready-mix

GD Harries take pride in supplying our customers with low carbon ready-mix concrete as standard, offering up to 50% carbon reduction for class A1-A3 concrete.

Our Greenbloc Standard Ready-mix concrete offers up to 50% carbon reduction and can be produced in all our concrete ready-mix specifications. It also offers the same price and performance as the 100% cement equivalent mix but with up to 50% lower carbon embodiment, and it conforms to BSEN 206 and EN 8500 series.

Operating our business in a sustainable way is at the forefront of our minds and we want to stand with our customers by offering high quality ready-mix concrete products, without compromising on making the right choice for the planet.
