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

TBM Under Ocean Waters - AvantiGrout to the Rescue

Avanti Trenchless and Underground Construction (T&UC) 2014

  • When the Port of Miami wanted to deepen its existing channel, an aging sanitary sewer main belonging to Miami-Dade County had to be lowered.

Foundation Grout Solutions

Avanti 2012

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.

Ultrafine Pozzolanic Cementitious Grout White Paper

Brian Jeppsen, VP R&D at US Grout, LLC of Malad City, Idaho 2013

  • Standard Cementitious Grouts have two main limitations: One, the inability to effectively penetrate rock microfractures or dense, silty soils, and two, poor performance due to deleterious curing problems inherent in standard concrete.

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?

Blocking Artesian Flows

American Cyanamid AM-9 Technical Manual 1960

  • This 440- foot earth and rock- fill dam is located in a deep canyon along the Deschutes River in Oregon on a foundation of Pelton basalt, created by a series of lava flows.

Grouting River Beds for Dam Corewall Construction

American Cyanamid AM-9 Technical Manual 1960

  • A high earth- fill dam was being constructed across the Grijalva River. After diversion of the river, seepage was still occurring through the riverbed sands.

Stabilizing Soil for Construction Tunnels

American Cyanamid AM-9 Technical Manual 1960

  • In this project, two 12- foot diameter by 270- foot long tunnels were to be driven beneath thirteen sets of live railroad tracks on the property of the New York Central, New York, Susquehanna, and Western Railroads.

Sealing Leaks in a Dry Dock

American Cyanamid AM-9 Technical Manual 1960

  • Fitzroy Dry Dock, the oldest in Australia, was constructed in the days of sailing ships. Time and water pressure had eroded some of the jointing material, and sea water was entering the dock in a number of places.

Shutting Off Seepage at Missile Silo

American Cyanamid AM-9 Technical Manual 1960

  • Excavation had progressed 80 feet at this missile installation when water seepage became a problem.
