SCDD currently has three experienced teams capable of providing trenchless underground pipe laying services.

We specialise in the installation of conduits and pipelines beneath paths, driveways, roads, rail, airport runways, congested and environmentally sensitive areas.

We are constantly upgrading, modifying and expanding our fleet so that we are able to provide a reliable and professional service, at a competitive price, for a range of projects.

We will provide the personnel and equipment required for installing single and multiple pipe of various sizes.

Horizontal Directional Drilling

Horizontal Directional Drilling is an efficient and cost effective steerable trenchless method of installing underground pipe, conduit or cable in a shallow arc along a prescribed bore path by using a surface launched drilling rig.

The HDD process has minimal impact on the surrounding area. HDD drilling is used when trenching or excavating is not practical or the area is environmentally sensitive. It is suitable for a variety of soil conditions and jobs including roads, footpaths, landscape, rail lines and river crossings.

The main benefits are:

Environmentally Friendly

Less Surface area disturbed

Reduced carbon footprint generated due to the non removal and replacement of surface

Reduced air, noise and visual pollution

Suitable for sensitive and historical areas

Existing trees can be left undisturbed.


Reduced chances of interfering with existing services

Minimal disruption to surface activities and structures

Reduced adverse impacts on community, business and commuters

Less delays due to adverse weather conditions

Vacuum Excavation

Vacuum Excavation or Potholing are the terms used to describe the location of underground utilities via the use of high powered vacuum machinery.

Using high-pressure water with an air vacuum, vacuum excavation is the safest, most convenient and environmentally friendly way to get a true visual location on underground services and utilities without the use of traditional trenching or digging.  This process minimises the risk of damaging underground services.

Vacuum Excavators are also used to remove unwanted material from an area, mainly mud, dirt and slurry around underground utilities.
