Shotcrete sheathing systems are designed to offer economic and fast solutions in deep excavation applications. Earth pressure in these systems is balanced by the soil nails which function as passive anchorage. In this sheathing method which can be applied in cohesion and hard formations, the contact of ground with air is blocked with shotcreting. Shotcrete is applied to mesh steel surface. Soil nails produced from the surface covered with shotcrete are planned permanent or temporary as intended.


Shotcrete soil nail sheathing systems are frequently applied in temporary deep excavations, which are not much deep, in urban areas. On the other hand, permanent sheathing applications are preferred in solution of chamfer stability problems on roads.

Shotcreting can be defined as blasting the slurry made of water, aggregate, cement and optionally solid mixture with compressed air onto the desired surface.
