Retaining Pond Standpipe

By Chris on 11-10-2018

Mine discharge was infiltrating an overflow flow pipe located in a retention pond.  The continuous flow of the contaminated water was causing environmental concerns at the exit location.  Using the polyurethane grout Hyperflex, grouting contractor Sub-Technical was able to stop the flow of the polluted orange water.  The application process was relatively simple.  A single hole was drilled, a packer inserted, then Hyperflex injected using a grouting pump.  The Hyperflex reacted with the water, expanded, and sealed off the infiltration.
