Trenchless Pioneers Build on Past, Look to Future

Sharon M. Bueno Trenchless Technology August 2016

  • Avanti International Continues to Educate and Develop Chemical Grouting Industry

Irreversible Changes in the Grouting Industry Caused by Polyurethane Grouting

Alex Naudts DFI/Geo-Institute of the A.S.C.E 2003

  • An Overview of 30 Years of Polyurethane Grouting

Sorting Out the Grout

Britt N. Babcock, PE, Director, Geotechnical Division World Tunnelling 2013

  • Tunnel contractors can choose whether to use cement or chemical grouts. To help them out, Britt Babcock discusses both types, which to use, when to use them and why...and an idea of how much it will all cost.

Mitigating Inflow Due to Both Primary and Secondary Permeability in Mining

Brad Crenshaw, PE - General Manager - Ground Engineering Contractors AEG News 2013

  • Groundwater infiltration can be due to either primary or secondary permeability. When both types of permeability are present, mitigation requires versatility and cooperation between multiple project participants.

Cement Grout vs. Chemical Grout

Britt N. Babcock, PE, Director, Geotechnical Division Avanti 2013

  • Cement Grout vs. Chemical Grout: Which One to Use, When, and Why. A White Paper providing guidance to the Geotechnical Community

To Grout Or Not To Grout?

Brad Crenshaw, P.E. P.G., Scott Langley, Vic Daiber, P.E. P.L.S., Donald Rigby World Coal 2013

  • Groundwater can bring an underground mining operation to its knees, but it can be controlled with ingenuity, co-operation and grout expertise

Controlling Seepage During Shaft Sinking

American Cyanamid AM-9 Technical Manual 1960

  • In order to reach newly discovered lead deposits, St. Joseph Leak Company had to sink large diameter deep shafts through permeable Lamotte Sandstone carrying ground water at high pressures.

Sealing Sandstone to Permit Shaft Sinking

American Cyanamid AM-9 Technical Manual 1960

  • In one of the deepest drilling operations in British coal mining history, plans called for the sinking of two 3,000-foot shafts, one to be used as a main coal-hoist shaft with skips, the other to house a conventional cage hoist.

Long-Term Performance of Grouting Around a Flood Control Bulkhead in Shoals, Indiana

Avanti 2006

  • 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.

Sealing Leaks in Coal Mine Slope

American Cyanamid AM-9 Technical Manual 1960

  • During the winter months, small drips from the roof froze into large ice masses, obstructing the passage of men and equipment, and becoming a safety hazard.

Cutting Water Flow in Colliery Drift

American Cyanamid AM-9 Technical Manual 1960

  • Problem: In driving two drifts for this new project, several badly fissured water-bearing rock zones were intercepted. Upon completion, water at the rate of several thousand gallons per hour was entering the drifts from a subterranean water table.

Consolidating Weakly Cemented Sandstone During Cross-Cut Construction

American Cyanamid AM-9 Technical Manual 1960

  • Problem: At Seafield Colliery, three cross-cuts, 16-17 feet wide by 12- feet high, were being driven horizontally through the Millstone Grit series, which contained many weakly cemented and porous sandstones.
