Soil Nailing is a technique for stabilizing and reinforcing slopes and deep cuts and for constructing retaining walls from the top down.

Inclusions, such as steel bar, are drilled and usually grouted into the soil mass creating one composite mass. The soil face is then

typically covered with shotcrete, although there are many other architectural covering options available.

Soil Nails offers a flexible earth retention system technique as it can be used for irregular shaped cuts and soil masses and the equipment is portable and easily modified for tight spaces and locations.
Sinorock uses a variety of soil nail systems and techniques such as helical soil nails, self drilling, hollow bar nails, and conventional reinforced grouted nails. Utilizing a variety of drill rig and excavator attachments, soil nailing with limited access is possible.
With self drilling soil nails, grout is ini­tially used as a flush­ing medium and finally as the per­ma­nent body of the struc­tural nail.
After drilling the nail is trem­mie grouted and they are nor­mally used in con­junc­tion with a soil reten­tion sys­tem such as a geogrid, steel mesh or similar product. This is sometimes overlain by topsoil (pos­si­bly retained by a geoweb) or directly seeded for the cul­tivation of grass.
