Soil nailing is a well suited excavation support and protection especially in situations 

with height , vibration, and noise restrictions. This shoring method involves installing 

grouted steel tendons into drilled holes in soil or rock, embedding the nail heads and 

exposed cut in reinforced shotcrete. The soil nail wall is installed from top down in 5-7 ft 

steps until the bottom of excavation has been reached.

 

The soil nail wall can be both temporary with a rough gunned finish or permanent with a wide range of architectural shotcrete finishes such as faux rock, patterns or flat troweled 

finishes. Advanced Shoring has installed over a million square feet of temporary and 

permanent soil nail walls in sizes ranging from 50 sf to over 50,000 sf and has adapted some of its equipment specifically to handle this type of work. We provide architectural 

shotcrete finishes through our sister company Advanced Shotcrete. 

Sinorock have the qualifications and experience in the concept of soil nailing, which 

briefly is to reinforce and strengthen existing ground by installing closely spaced grouted 

steel bars, called ”nails,” into a slope or excavation as construction proceeds from the 

”top down.”

As soil nail construction requires temporary stability in both the staged excavation and 

also the drilledhole stability, any soils with sufficient temporary self-support of about 2m 

sub-vertical height for minimum of 1 to 2 days and hole stability for minimum four hours are considered suitable ground for soil nailing.
