This paper summarises the results of a full-scale trial soil nail wall reinforced with the PermaNail system. The trial wall was constructed in a slightly cohesive granular fill and was eventually 6.5m high, with a face angle of 20 to the vertical. After six months, and a surcharge load of 105t (equivalent to a surcharge pressure of 32.9kPa). The maximum recorded horizontal movement of the face was 3.5mm.
