AV-100 Chemical Grout Files

Magazine Article: Miami-Dade Grouting Program Running Full Steam Ahead

Published Year: 1993

  • Sixteen hours a day, five days a week, almost two thousand hours a month the Miami-Dade grouting crews are locating and chemically sealing leaking joints in the sewer line collection system.

Case Study: Blocking Artesian Flows

Published Year: 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.

Case Study: Bracing Crumbling Dock

Published Year: 1960

  • An eight-year-old loading and mooring dock, 1600 feet long, at Sept Iles was showing distress. It had been constructed by driving sheet piling then placing a heavy rockfill as a base.

Case Study: Consolidating Weakly Cemented Sandstone During Cross-Cut Construction

Published Year: 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.

Case Study: Constructing Grout Curtain for Dam

Published Year: 1960

  • The Columbia River Valley at the dam site is a wide canyon dividing the Columbia Plateau on the east from the Entiat Mountains on the west.

Case Study: Controlling Seepage During Construction of Underground Missile Bases

Published Year: 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.

Case Study: Controlling Seepage During Shaft Sinking

Published Year: 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.

Case Study: Cutting Water Flow in Colliery Drift

Published Year: 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.

Case Study: Grouting Foundation for Dam Construction

Published Year: 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.

Case Study: Grouting in Fissured Rock

Published Year: 1960

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

Case Study: Grouting Jointed Rock in Dam Foundation

Published Year: 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.

Case Study: Grouting River Beds for Dam Corewall Construction

Published Year: 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.

Case Study: Improving Oil Production in a Water Flood Cave

Published Year: 1960

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

Case Study: Increasing Oil Production

Published Year: 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.
