Drilling and underground services throughout the South Island

At Welshy Contracting, we can help install any fibre cable or power cable underground with the help of four directional drills. If you are looking for open trenching without disrupting any property, then directional drilling is the way to go. When drilling isn’t an option, our chain trenches can open neat and tidy trenches in the most difficult of locations. Established in 2004 in Ashburton, Welshy Contracting work throughout the South Island on drilling and underground services.

We provide the following drilling & underground services from Canterbury:

  • Install fibre and power cables
  • Chain trencher
  • Hydrovac truck to help locate underground hazards
  • GPR machine and locators to locate and mark out power and phone cables, water pipes and sewers

Ashburton & Canterbury Hydrovac services

Before installing any fibre and power cables, here at Welshy Contracting, we have an experienced and qualified team that can locate any underground services with the use of our GPR machine or locators. We can also use the Hydrovac truck to help locate any underground hazards.

We’re experienced when it comes to power cable & fibre installation

The Welshy Contracting team can drill down any footpath, berm or road crossing, then haul the fibre cable, which is then followed by our jointer. Every operator has the appropriate driver licenses, WTC endorsements and competency to fulfil the job to the highest quality. Our directional drillers have WTC endorsement and a Class 5 license. Which means moving the drill from place to place is no hassle. Health and safety are of course a priority. All our team members have Site Safe and First Aid.
