2. European Standard prEN 14199

3. Main Issues of Understanding
Definition of Micropiles: Cross sectional size and application(?)
Used Materials: Steel components, grout and concrete
Execution: Drilling or driving, filling or pressure grouting
Quality Control: Testing, recording and supervision

4. Comparison between original concept of Root Piles and standards

5. Concluding Observations
Tendency to higher bearing capacities
Interference with standards for drilled and driven piles
Missing awareness of potentials of soil - micropile composite performence
Missing design rules for reinforced soil concept: Academia is challenged, Eurocode 7 needs it!
