The long-term performance of the end-product is more important. For this reason, we have re-visited an 18-year-old mine grouting project that took place to prevent the flooding of a gypsum mine in Shoals, Indiana.

Many U.S. municipalities and utility districts face federal Environmental Protection Agency (EPA) mandates to correct water quality problems caused by discharges from combined sanitary and storm sewer systems
Grouting has occasionally been thought of as a more temporary solution, a stop-gap. But recent testing of two 20-year old acrylamide grout rehab projects indicate that grout can certainly stand the test of time.
This is a case study whereby acrylamide solution grout was used to achieve the “target residual permeability value” in the rock formation below a future tailings dam for a large copper/gold mine in Argentina.
