This seminar will cover topics related to advanced specialty geotechnical techniques associated with tunneling construction. Topics will include: 1. Ground freezing and jet grouting for adits and difficult connector tunnels. 2. Emergencyground improvement for TBM retrieval with ground freezing and grouting. 3. Support of excavation and groundwater control in restricted access urban conditions. 4. Settlement mitigation with compensation grouting and state-of-the-art instrumentation. 5. Case histories of shaft construction with diaphragm walls, secant piles and CSM.

Keller North America provides a wide range of geotechnical engineering and construction services to improve soils in-place and to both construct new and rehabilitate foundations.
