Eco Range

For added peace of mind, all of our products are
available in Eco and Eco+.

Our Eco Range combines locally sourced, recycled steel slag aggregate with a bio-binder, which can be made with non-recyclable polymers that would otherwise go to landfill or be incinerated.

Our Eco+ Range incorporates organic materials which significantly reduces the product’s carbon footprint further, helping to achieve your net zero ambitions.
