72-Inch Pipe Stabilized With Chemical Grout

B. Jay Schrock, P.E. Trenchless Technology - June 1994 1994

  • At a paper mill in Alabama, a weakened joint was found in a six foot diameter pipe carrying more than two millions gallons per hour of effluent.

Chemical Grout Stops Leaks in Concrete Dams

Avanti 2009

  • Chemical grout has been stopping leaks in concrete structures for over 25 years. In concrete dams, chemical grout forms a permanent, flexible, compression-type seal that stops water movement.

Rembco Undertakes New Project for Hazardous Waste Containment at ORNL

Avanti News + Views 2005

  • "Locking hazardous materials in place is almost always safer and more cost effective than removing them for treatment, and there typically is no ongoing maintenance" -Clay Griffin, President of Rembco Geotechnical Contractors, Inc.

Ultrafine Cementitious Grout

Acrylamide Grout Aces 20-Year Test

Greg Thompson Trenchless Technology 2008

  • 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.

AV-100 Chemical Grout Solves Leakage Problems in Tailings Dam for Large Copper/Gold Mine in Argentina

Avanti 1998

  • 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.

Preventing Leaks While Sinking Tunnel Shafts

American Cyanamid AM-9 Technical Manual 1960

  • Problem: Twelve manhole shafts for a mile-long tunnel, part of a trunk storm sewer being constructed 50 feet below a Dallas Freeway, had to pass through 20 to 25 feet of saturated sand before reaching bedrock.

Increasing Oil Production

American Cyanamid AM-9 Technical Manual 1960

  • Problem: A petroleum production water flood project was not responding well to flooding. An injection profile indicated that about half of the injected water was entering the zone between the two perforated intervals.

Grouting in Fissured Rock

American Cyanamid AM-9 Technical Manual 1960

  • Pumping costs at Cedar Bay Mine were becoming excessive, as new drifts were opened and total seepage into the mine increased.

Grouting Saves Effluent Pipeline and Maintains Plant Operations

Dick Berry, Rembco Water Control Quarterly 1996

  • During a routine facility inspection at a major West Coast paper plant in Canada, a small leak appeared near the shoreline where an underground 42-inch fiberglass reinforced plastic pipe carried effluent to diffusers in the ocean.
