Our Services

Groundworks is just the start of what we do

At Mackoy, we know there is much more to groundwork than just soil-stripping and muckaway. That's why we have developed a unique service where clients are partnered with one contractor who specialises in a range of groundwork and civil engineering processes, creating a single point of contact for multiple stages.

Our experts are skilled in a wide range of niche groundworks services, from initial site investigations – that determines the physical make-up of a development plot and its construction suitability – to specialist CAT and CCTV scans that identify the locations of live underground services.

Our groundworks services are not only essential but protect both investments and people. When a development gets the green light, Mackoy ensures the infrastructure is in place to conduct works safely using the best equipment.

This ability to take ownership of multiple elements of a development is what sets Mackoy apart and makes us a leader in groundwork infrastructure and civil engineering in the South. However, we are not only trusted by top regional developers in Hampshire, Dorset, Sussex, Surrey and Berkshire but throughout the whole country, with our client list including some of the largest and longest-serving housing developers in England.
