Creek Draining into Abandoned Mine Creating AMDComments Off on Creek Draining into Abandoned Mine Creating AMD
This dry creek bed was created by the water draining into an abandoned mine below. Not only was this creating a dried-up creek, but the water also leaving the mine at another location was creating acid mine drainage. To prevent the water from entering the mine, the creek bed was injected with polyurethane grout. The grout, Hyperflex, sealed off the leak paths and will help keep the water on the surface. Hyperflex is a single component, moisture activated material that is NSF/ANSI/CAN 61 approved for potable water. Hyperflex is manufactured by SealGuard, Inc. and was installed by grouting contractor Sub-Technical, Inc.
