Cuttable Solutions
Cuttable support is mostly used in the longitudinal direction of the tunnel (portal, face) when temporary stabilization is required before moving to the next phase.

Also, Mechanized Tunneling is becoming standard in urban areas, especially for underground metro projects. This modern technique is calling for new kinds of systems, in particular, cuttable reinforcement bars for concrete structures (like Soft-Eye in D-walls) and cuttable ground anchors.

Radial & Lateral Support (Roof & Wall)
عند بناء نفق عن طريق الحفر والتفجير أو التعدين التقليدي، يجب دعم السقف والجدران.

Rock bolt is the first type of support installed before any other kind of mesh or lining is applied. Depending on the construction sequence and technology, both temporary and permanent bolts can be offered.
