The rehabilitation of the Goose Pond Dam was initiated by the New Hampshire Department of Environmental Services to address significant leaking of the dam that threatened multiple downstream towns. Improvements included flattening the downstream slope, updating and improving the seepage collection system along the downstream toe of the dam…
Slope Stabilization in Kicking Horse Canyon – 2024 Honorable Mention Project
The Kicking Horse Canyon Highway, part of the Trans-Canada Highway near Golden, British Columbia, has a rich history tied to the region’s rugged geography and vital transportation needs. Originally a narrow and winding route carved into the steep canyon walls, it was built in the early 1900s to connect the mountainous interior of British Columbia with the rest of Canada.
Ice Harbor Dam Rewinds and Turbine Runner Replacement – 2024 Outstanding Infrastructure Project
Ice Harbor Lock and Dam was authorized by the River and Harbor Act of 1945. Constructed in 1956, the project includes a dam, a powerhouse, a navigation lock, two fish ladders, a removable spillway weir, and a juvenile fish bypass facility. It provides navigation, hydropower, flood risk management, fish and wildlife habitat, recreation, and incidental irrigation.
The Diversity of Shotcrete
It is truly paramount to recognize the diversity of solutions available because of the versatility that shotcrete offers. Shotcrete placement provided more efficient, sustainable and durable concrete solutions in these two cases than could have been achieved with a form-and-pour approach.
Early Age Strength Testing for Shotcrete: 2024
For improved safety in tunneling and mining projects that use shotcrete for ground support, early shotcrete strength should be evaluated by testing. Based on their range of effectiveness, two procedures stand out: The new Hilti BX 3-SCT stud driving method and the beam end tester.
Geohazard Mitigation: Why Shotcrete?
To improve safety and mitigate the risks of rockfall events along I-65 in Giles County, TN, GeoStabilization partnered with the Tennessee Department of Transportation and a local construction company.
Rapid Strength Gain Dry-Mix Shotcrete: A Unique Solution for Highly Complex Projects
The construction industry must embrace new technologies and innovations to address today’s challenges. With its unique features, shotcrete stands out as a placement solution, meeting the most stringent project standards and offering unmatched benefits compared to traditional form-and-pour concrete.
The Application of Shotcrete in Shafts: Work Preparation and Construction Based on Various Projects in Central Europe
Shotcrete shafts often present unique challenges for construction projects. In many cases the construction method is different from the one used in the main tunnel (often using a TBM), presenting challenges recruiting experienced and certified personnel for the shaft works.
Modelling the Service Life of Structures with Cast-in-Place Concrete vs. Wet-Mix Shotcrete
When properly designed and applied, wet-mix shotcrete provides equal or increased service life for reinforced concrete structures compared to cast concrete.
Polymer Rubber Gel Technology: High-Performance Waterproofing for Shotcrete and Blind-Side Applications
The innovative GTS Polymer Rubber Gel waterproofing systems are proven and effective for underground construction applications.
