Tunneling Application


FiReP® FRP Rockbolts are corrosion resistant and
therefore the only currently available rockbolt system
which can be regarded as permanent even under difficult conditions
with aggressive water and rock deformations.

Because of the durability of the materials FiReP® FRP Rockbolt Systems
can be utilized not only as temporary support, as with regular steel rockbolts,
but also integrated into the calculations for the final load-bearing structure.
In-situ concrete shells can therefore be reduced or even eliminated.
