RoadTec is the specialised roading and pavement arm of Earthworx, delivering innovative road stabilisation and rehabilitation services across Northland.

We specialise in strengthening existing pavements through lime and cement stabilisation, dig-outs, and full structural rebuilds — improving durability, reducing maintenance, and giving roads a longer second life. Whether it’s forestry tracks, rural cul-de-sacs, or local authority upgrades, we tailor each solution to the ground beneath it.

Our work is backed by in-house civil engineering oversight and delivered using GPS-controlled machinery, so every layer is placed, compacted, and tested with precision. We understand subgrade behaviour, how to correct weak pavement structures, and when stabilisation can save thousands compared to full reconstruction. That knowledge means better outcomes for developers, councils, and the communities who rely on those roads.

Every RoadTec job is completed by trained Earthworx staff who know how to manage environmental controls, safety procedures, and QA requirements from start to finish. From rapid-response rehab to planned upgrades, we offer a smarter, longer-lasting approach to pavement performance.
