Repairs to Leaking Earthen Dam

American Cyanamid AM-9 Technical Manual 1960

  • Indian Kill Reservoir is a man- made lake (capacity 200 million gallons.) serving a portion of Sterling Forest, a community developed for scientific research, education, and suburban living.

Grouting Foundation for Dam Construction

American Cyanamid AM-9 Technical Manual 1960

  • A 300-foot rockfill dam with a central impervious core and a crest length of 870 feet was being built on a generally sound granite foundation, except on the upper right abutment where the rock was completely weathered to an in situ soil.

Search Efforts Continue After Hawaii Dam Bursts

The Associated Press MSNBC.com 2006

  • An 1890s-era plantation dam failed in the rugged hills above northern Kauai, sending water and mud surging through two homes and wiping out the only highway.

Shutting Off Water During Tunneling

American Cyanamid AM-9 Technical Manual 1960

  • A six- foot diameter tunnel, 139 feet long, had to be driven through a cinder-slag fill with voids estimates as high as 70 percent. The tunnel dropped 25 feet over its length and terminated in a cofferdam about 23 feet below river level.

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.

Controlling Seepage During Construction of Underground Missile Bases

American Cyanamid AM-9 Technical Manual 1960

  • Problem: With construction still in progress, numerous leaks appeared at the joints and bolt holes of corrugated steel-pipe tunnels connecting missile silos to control centers. Welding and sealing compounds failed to stop seepage.

Grouting Jointed Rock in Dam Foundation

American Cyanamid AM-9 Technical Manual 1960

  • Problem: Severe weathering along calcite veins, joints, and cracks, as well as the presence of three fault zones, have formed seepage channels which could endanger the performance of the dam.

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.

Stopping Water Infiltration in Sewer System

American Cyanamid AM-9 Technical Manual 1960

  • Problem: Pipe and joint deterioration in the city’s 50- year-old sewer system had led to heavy infiltration. Estimated flow often exceeded 6 million gallons per day.

Stabilizing Running Sand During Pipe-Jacking

American Cyanamid AM-9 Technical Manual 1960

  • Problem: A city water supply pipeline, 126 cm. in diameter, has to be placed under the Keiyo Highway in close proximity to an irrigation channel. The water supply pipe had to be placed without disturbing highway traffic.

Improving Oil Production in a Water Flood Cave

American Cyanamid AM-9 Technical Manual 1960

  • Problem: Water was pumped down a well to displace petroleum from the oil-bearing formation into an oil producing well.

Toronto Successfully Using Acrylamide Grout to Stop Tunnel Leaks

L.Narduzo, P.E., Leak Remediation Engineer for Toronto Transit Commission Underground Construction Magazine 2003

  • The Toronto Transit Commission (TTC) is responsible for one of the largest public transportation systems in North America. The tunnel leak remediation program was built around a solid foundation of expertise in the specialty field of grouting.

Methods to Control Leaks in Sewer Collection Systems (White Paper)

C. Vipulanandan, PhD, PE and H. Gurkan Ozgurel CIGMAT 2004

  • In recent years, federal and state regulations and mandates to reduce sanitary sewer overflows (SSOs) have resulted in requiring better maintenance and operating practices for wastewater utilities.
