Stream grouting uses the MICON RokLok™ polyurethane grouting system. Stream grouting offers a permanent solution to stream flow loss while reducing surface and ground water infiltration into underground workings.

The Process

• Holes are drilled under the stream before mining the area
• RokLok™ is pumped into the holes, sealing the strata beneath the stream
• The RokLok™ creates a subterranean blanket which protects the stream above
• Causes minimal disturbance to natural conditions
