Injection Systems for Waterproofing and Stabilization of Rock and Soil

Unexpected water ingress during tunneling can escalate project costs and cause significant delays in the overall project timelines. To counteract the risks involved with such challenging ground conditions, the Underground Construction Group (UGC) of BASF's Construction Chemicals division offers expert advice and products across a broad range of injection systems designed to address a wide variety of tunneling situations. The choice of injection system is dependent on such factors as water quantity and pressure, rock and soil permeability and cohesiveness, construction sequence, and final water-tightness requirements of the completed structure. Both pre- and post-excavation grouting have found increasing acceptance within the underground tunneling industry and both methods have also shown that their proper applications will lead to an increase in tunneling efficiency and safety. BASF has experience in the proper design and execution of many injection programs and this webinar will cover such topics as:

• Introduction and overview of standards in pre- and post-excavation grouting
• Reasons for grouting in tunneling
• Functional requirements
• Types of injection materials
• Cement injection
• Chemical injection
• Grouting in high-pressure water conditions
• Overview of grouting equipment and requirements
• Case studies
• BASF products overview

Please join us for this informative and interactive web seminar. You will be able to ask questions throughout the event via instant messaging.
