Conceptual Solution

• The nail-soil interaction consists of transferring the

resisting tensile forces generated in the inclusions

of soil nails into the slope through adhesion/bond

strength mobilized at the grouted nail-soil
interface.

• Estimation of pullout resistance of soil nail plays
most important role in the design of TerraNail®.

The pullout resistance is mainly based on bond

strength or adhesion at the soil and grouted nail

interface.
