We have pioneered HRB technology and applications worldwide. HRB is similar to traditional raise boring where a contact tunnel is bored horizontally.
Used where a horizontal excavation is required and a chamber is available at both ends.
Excavating tunnels through mountains to connect parallel metro and rail tunnels.
For nuclear storage tunnels or short tail races in hydro-electric plants.
Has lower support requirements due to stable circular excavation.
Improved production advance rates as a result of continuous excavating cycle.
Compact equipment design contributes to greater mobility. More cost effective
and reliable when compared to a TBM system.
