Tunnels are essential to modern infrastructure. NATM(New Austrian Tunneling Method) and
TBM(Tunnel Boring Machine) are most widely used methods to drill a tunnel. Both methods definitely
need to be stabilized with reinforced concrete on the drilled surface.

TBM·PC

APPLICATION

BUNDREX offers a wide range of products that can be ideally used for NATM and
TBM method depending on tunnel conditions.

The benefits of the TBM/Precast reinforced with steel fibers

Increases the crack control, impact resistance and durability of the precast.

SFRC precast segmet for TBM (Tunnel Boring Machine)

Shield TBM method, widely used to drill a tunnel, requires also to install precast segment which are reinforced with steel fibers replacing the current rebar.

Advantages of SFRC precast segment for TBM

It improves the durability of the precast reducing the manufacturing time and the steel material cost.
