What are the benefits of using HDD (trenchless technology)?

Trenchless technology is widely used for the installation or replacement of ducts and pipes for services, especially beneath rivers, canals, railways and busy roads. They are used in cities, parks, forests and places where the depth of installation makes the techniques more economical than open trench installation.

Advantages of trenchless technologies include:

  • Enhanced worker and public safety.
  • Reduced risk of damage to nearby nature, structures and utilities.
  • Reduced disruption to surrounding businesses, residents and the environment.
  • Cost effectiveness.
  • Possible uses for obstacle crossing where regular open-cut methods are not suitable.
