ABSTRACT:
A method and apparatus (10) for forming improved seals in boreholes (101) formed in host rock (100) by using the apparatus (10) to introduce a feedstock (60) into the borehole (101) and simultaneously subject the introduced feedstock to both compressive and shear stresses until the borehole becomes filled and sealed.
