Geotechnical Systems - DYWIDAG Soil Nail
DYWIDAG Soil Nailing is a passive system for stabilizing slopes and sidehill cuts or rock as well as for stabilizing construction pit walls if deformations are irrelevant.
The load-bearing system significantly differs from ground anchors (actively tensioned) and tensile piles. In the case of soil nailing, the load-bearing capacity of the complete soil is increased because it is consolidated by the soil nail.
The soil is nailed into secure areas of the slope located further inside the hill. Consequently, tensile and shear forces act on the nail. In order to achieve this effect, the nail can only be placed at certain, limited distances towards each other. The nail do not act individually, but as a complete nailing system.
