Injection system


Borehole seals with internal plastic pipes are mainly used in mining and tunneling 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/ground. The special feature of the plastic borehole seals is that they can be bored out easily if required.
