Make Sense of Mixed Ground

Cost: FREE

Machine selection can make or break a trenchless job, and one of the deciding factors is project geology. Which machines work best in different ground conditions and why? What should be done in known mixed ground or if the ground changes?

Learn more at our webinar, which will discuss trenchless solutions for projects over 24 inches in diameter based on a wide variety of geologic conditions. Recent case studies and machine performances will also be examined from projects around the world.

Soil Conditioning Solutions for TBM Excavation

TBM excavation has to successfully manage a variety of geological conditions. Since soil behavior is never perfect, soil conditioning additives are introduced in front of the cutter head to change the natural rheological characteristics in order to maintain optimal advance rates and/or stability to minimize or prevent ground movement on the surface.

This webinar will discuss these various ground conditioning agents and how they are used to aid in a successful excavation with respect to optimized advance rates and safety. BASF Construction Chemicals has worldwide experience in the proper design and execution of many soil conditioning programs and this webinar will cover such topics as:

• Changing the soil properties
  
• Torque and wear reduction at the cutter head
  
• Changing the soil permeability
  
• Benefit of anti-clay-agents
  
• Wear reduction on hard rock TBMs

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.
