SenX is a group of industry professionals with years of experience and a breadth of expertise across all areas of operation in the aggregate industry. We have a background in a wide range of construction materials, including asphalt, concrete, aggregates and manufactured sand.

Our ethos is to work with our clients to achieve the best possible results – even if this means turning up at the weekend to get the job done. We are able to draw on a wider group of associates and specialists to tailor the right team for the job, site and objectives.

During our careers, we’ve worked all over the world, which gives us unique insight into how local cultures affect expectations and outcomes.

What’s in a name?

Senex, from the Latin meaning ‘old man’, is the term given to a wise sage or mentor. We’re not all men, and we’re not all (that) old, but we pride ourselves on our experience and judgement.
