The SSL permanent anchor method consists of two techniques: the P-type and the M-type, which are both expansion pressure types.
The SSL-P type anchor body is suitable for clay and weathered rock, where the anchor fixation part is enlarged, and an anchor body is created inside the enlarged hole using grout. This method ensures the anchor's load capacity based on the bearing strength of the fixed ground in the enlarged section. The SSL-M type anchor body is suitable for soft to medium hard rock, where after enlarging the anchor fixation part, the anchor body is inserted and expanded in the enlarged section, ensuring the anchor's load capacity based on the bearing strength of the fixed ground in that section.
