Presentation transcript:

European Standard prEN 14199

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

Comparison between original concept of Root Piles and standards

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!
