Diamond trenching

The term diamond trenching describes a process for laying pipes for fiber optic cables, in which narrow trenches and slots are made in floors and asphalt in a minimally invasive manner by using diamond cutting technology. This method of laying takes up little space and enables quick completion of pipe and fiber optic lines.

With the help of our diamond trenching machine a production capacity of min. 1 m / min is possible while cutting a trench into the upper layer (asphalt) and base layer, as well as the simultaneous laying of a large number of single pipes on the bottom of the trench using a laying unit specially developed for this process.

The specific diamond trenching blades are designed for cutting, respectively grinding all obstacles and materials that are installed in the ground. The main benefit is a monotonous, very even cut that leaves straight walls. A simplification of the filling and sealing process is a result of that and is also very inexpensive due to the narrow cutting width.

Diamond trenching in action


Method and machines is a result of a long term experience and colaboration of both our R&D department and our Swedish joint venture, NEXTEC System AB. NEXTEC System AB has many years of experience in building telecommunications networks and offers a complete system for which LISSMAC supplies the trenching machines and diamond tools.

The system consists of:
  • Conventional ducts and infrastructure studies
  • Determination of duct depth with the help of GPR on demand
  • Trenching with diamond blades and duct installation
  • Filling the trench with Nextec- inject
  • Permanent reinstatement of the road surface
