At March Cato, we love a challenge, whether it’s deep, large diameter, lots of interfaces, complex ground conditions or difficult access – whatever the challenges are, this is what we are all about. Over the last 29 years, we have tackled some of Auckland’s most difficult and high profile infrastructure projects and have grown an enviable reputation with our fantastic clients for the safe delivery of these challenging works. We specialise in the following:

Open Trench Construction
We own and operate a large, well-maintained fleet of excavators ranging from our small 1T machines, all the way up to 47T excavators. We are particularly proud of our fleet of 20T and 30T zero swing excavators which offer tremendous power within a small footprint, enabling us to break rock, lift pipes and complete works in narrow streets and residential areas. In addition to these machines, we also own a number of sheet pilers, rock breakers as well as our own bespoke design trench shields and shoring systems, ensuring that we are able to trench through a variety of ground conditions, from very week silty sands, peats and clays, right through to cemented tuff and basalt.
Our trenching crews are supported by a fleet of 6W and Artic Trucks, which also includes a Transporter, Hydrovac and Hiab as well as well as our own, in-house traffic management team, who are experienced in dealing with the unique conditions and environments that we operate in.
