The service offer comprises a number of related disciplines including trenching, horizontal directional drilling, cable installation, full design and installation, jointing/splicing services and traffic management.

Thanks to our team of experts we’re ready to work on any size project, whether in the centre of a busy city or on a remote mine site.

There are few obstacles that we can’t overcome as we are experienced in directional drilling in densely populated urban areas, under major roads, across rivers or in difficult terrain like solid rock.

Trenching Services

Open trenching is the traditional method for laying cable and is still the simplest and most effective solution where conditions permit.  Diamond Underground Services have specialised equipment including D8 rock saws, rock breakers, and a wide range of trenching machines.  We are able to operate in any ground conditions, in all locations.  Our trenching services also include highly expertised Pit & Pipe construction teams, capable of handling any size project from end to end.

Horizontal Directional Drilling

Using our high quality fleet of Ditchwitch and Vermeer directional drill rigs enables us to complete projects where roadways, waterways, congested and environmentally sensitive areas preclude the use of other methods. We have the ability to install all sizes of conduit and cables in any ground condition or location.  Horizontal Directional Drilling causes minimal disruption to above ground infrastructure. This method also reduces the need to close public roads, and saves costs and time associated with reinstatement of civil amenities such as paving, road surfaces and vegetation. Our drilling crews have vast experience and knowledge in Directional Drilling.

Cable & Asset Installation

We deliver a full range of cable laying, hauling and cable ploughing services in either direct buried or open trench excavations. Diamond have the inhouse capability to install primary equipment such as transformers, streetlights, exchange racking and super structure using fully qualified and accredited personnel.  With our large fleet of regularly maintained and service mechanical plant, the company is able to undertake even the most complex and demanding installations.

Full End-to-End Design and Network Installation

With over 10 years’ experience, Diamond’s Design Team leads the way in producing quality complex Network designs for Australia’s largest Telco and other state based utilities. These designs are developed with our clients from Concept to Construction and include a full integrated set of construction plans.  Utilising 100% internal Construction resources allows seamless handover from Design to Construction teams, ensuring client expectations and timeframes are met. Client interaction at any point of a project is with a Diamond person actually undertaking the works.
