1.1.1.1. Treatment under existing structures

Try these first

1. 1.

   What is compaction grouting?

   Hint

   Think about how it interacts with the surrounding soil.

2. 2.

   Name one benefit of permeation grouting.

   Hint

   Consider the methods to control groundwater.

3. 3.

   What is the primary goal of compaction grouting?

   • Increase soil moisture
   • Reduce soil density
   • Increase soil density
   • Remove soil

   Hint

   Focus on what compaction specifically does.

4. 4.

   True or False: Jet grouting can be used for both stabilization of loose soils and supporting structures.

   • True
   • False

   Hint

   Consider its range of applications.

5. 5.

   Design a permeation grouting plan for a site prone to groundwater issues. Consider soil compositions and expected pressures.

   Hint

   Think about different soils and optimal fluid characteristics.

6. 6.

   Evaluate the risks of using jet grouting in a densely urbanized area with many existing structures.

   Hint

   Consider the surrounding environment and existing conditions while providing solutions.
