Borehole Seal
Borehole seals with internal polymer pipes are mainly used in mining and tunnelling to seal boreholes or for filling works. Materials as synthetic resins, mineral materials etc. are injected through the borehole seals for consolidation of the surrounding rock. The special feature of the polymer borehole seals is that they can be bored out easily if required.
