Mitigating impact on our communities is at the forefront of Diona’s thinking on all projects.

A critical tactic we employ is the inclusion of trenchless construction methods, which includes:

  • Horizontal Directional Drilling (HDD)
  • Micro-tunnelling
  • Horizontal Auger Boring
  • Pipe Jacking
  • Pipe Bursting
  • Pipe Insertion/Slip-lining.

These methods significantly reduce disturbance to the environment and community, saving money, improving efficiencies and resulting in more positive responses from clients, community members, and other stakeholders.
