Our Services

Earthworks is just the start of what we do

At Mackoy we know there's so much more to groundworks than just soil stripping and muckaway. That's why our unique services span multiple stages of the groundworks and civil engineering process. Allowing you to work with a single contractor who specialises in it all.

Our operatives are experienced in a wide remit of niche groundworks services. From initial site investigations that reveal the physical makeup of a development plot and determine its suitability for building. To specialised CAT and CCTV scans to identify the locations of live underground services. The essential groundworks services we provide protect investments, and people. Ensuring that when a development does get the green light the infrastructure is in place to conduct works safely, and with the best equipment.

This ability to take ownership of multiple elements of a development is what sets us apart, and makes Mackoy a leader in groundworks infrastructure and civil engineering in the South. Trusted, not only, by the top regional house builders in Hampshire, Dorset, Sussex, Surrey and Berkshire but by the nation's largest and longest serving housing developers too.



From getting a plot of land primed for development, to creating the integral underground infrastructure to service new homes with energy, waste, and water. Our groundworkers transform the development sites we work on. Turning raw earth and rubble into the footprint for new communities to thrive.



Civil Engineering

Civil engineers can help you realise the vision for your project. Performing the complex calculations that take your building from an architect's blueprint to a viable three-dimensional design. Ensuring the structure is solid, sound, and safe without compromising on its character or aesthetics.
