Curtain Grouting Manholes and Underground Structures

Daniel Magill NASSCO 2010

  • Picture this: You’re standing in a brick manhole that is 50 years old and leaking extensively all around you. You’ve already been working for over an hour and for every leak you stop, several new leaks pop up. Now what?

City of Dearborn Tackles Complicated Grout Curtain Project

Jeff Griffin, Senior Editor Underground Construction Rehabilitation Technology 2010

  • 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

When Grouting - Don't Forget the Soil

Richard M. Berry, MASCE Rembco 2000

  • When soil or rock improvement or modification is needed, grouting is one of the options called for.

Using Grout to Lock Pollution in Place

Jeff Griffin Underground Construction Magazine 1998

  • In Pennsylvania, Rembco used grouting to contain oil leaking under an oil refinery’s sea wall. The concrete wall had been constructed on top of old wharf piling. Over time, tidal action caused erosion, resulting in leakage at the wall’s base.

Chemical Grout Stops Leaks in Concrete Structures. Permanently.

Avanti 2000

  • Leaks in concrete structures keep coming back unless they are permanently sealed with chemical grout.

Trenchless Technology: Avanti Leads in Industry Development & Education

Allen Thomas Trenchless Technology Magazine 1994

We Kept the Airplanes Flying with Chemical Grout!

Jackie Spurling, P.E., Vice President, Stanley Engineering Company, Houston, TX Avanti International 2000

  • In 1997, serious leaks developed at George Bush Intercontinental Airport in a long utility tunnel connecting a passenger terminal with the central plant.

Costs of Chemical Grout (Would You Spend)

David Magill Avanti 2009

  • Are you spending thousands of dollars each year treating clean water? Recent studies and over 50 years of experience indicate that America's first trenchless technology is still the best, most cost-effective, long-term defense against infiltration.
