                  c.  Nailing. Nails are installed  perpendicular  to and through the failure
                  plane, and are designed to resist bending and shear (rather than tension)
                  using geotechnical engineering principles. Potential failure surfaces less
                  than 2 m deep normally require the nails to be wider near the top, which
                  may be achieved with steel plates fastened at the nail heads.

                  d. Geo-grids. Geo-grids are synthetic  materials used to reinforce  the
                  ground. The insertion  of geo-synthetic  reinforcements  (generally  in the
                  direction  in which the deformation  has developed)  has the function  of
                  conferring greater stiffness and stability upon the ground, increasing its
                  capacity to be subjected to greater deformations without fracturing
