Every day, all across the south, our groundwork operatives use powerful excavation plants to muckaway and move thousands of cubic tonnes of earth for our clients. This helps to create essential infrastructures to – literally – lay the foundations for new residential housing developments in Britain.

But that's not all we do. We specialise in groundworks and civil engineering - find out more about us.


What We Do

Our groundworkers create a construction project's vital infrastructure by balancing powerful excavation works with complex technical processes, from clearing a site of its topsoil layer to setting out the foundations of what will, one day, support a new home.

Civil Engineering

Our civil engineers use environmental and structural expertise to bring a building to life. Not only do they ensure a development project can be delivered on time and on budget, they also provide the complex calculations needed for a mechanically sound construction.

Earthworks digger mound reduction for Mackoy Groundworks


The first step in any new development, our earthworks prepare the ground for excavation. This is done by stripping away the topsoil, clearing the site of vegetation, removing excess earth (muckaway) and leveling out any unevenness (cut and fill) to make way for groundbreaking to begin.
