If we apply compression on the sides of the wall cross section with bilateral tendon prestressing, we will neutralize 1. the tensile and without tensile there is neither 2. bending nor 3. critical failure area nor 4. shear of the coating concrete nor 5. deformation, so neither 6. failures, and will 7. increase the cross-sectional strength to the cutting base. If the prestressing tendon is anchoring to the ground with anchoring mechanisms then 8. we will divert the tipping moment of the wall into the ground, preventing deflection to the beams, and 9. we will have the control of the displacements by controlling the tuning and the inelastic displacement so 10. we ensure greater strengths in the "duration" 11. The anchoring in the ground does not allow subsidence so it excludes this kind of deformations. 12. We thoroughly check the foundation soil since with the drilling we take soil samples to check its quality.
