A crimped connection system and methods for use in connection with the construction of earth walls is disclosed. A grid-type soil mat may be provided with a number of crimped ends. The crimped ends may be adapted for engagement through the use of a locking member with another soil mat or with a plurality of anchors partially embedded within a precast concrete panel. The plurality of anchors may be formed as part of a gang or unitary structure to facilitate alignment of the anchors when being cast into the precast concrete panels.
