ABSTRACT:
A soil reinforced retaining wall for an earthen formation is provided by embedding planar soil reinforcing mats in the formation at vertically spaced intervals and securing face mats between the soil reinforcing mats. The face mats include fingers extending distally from the edges thereof for engagement with opposite sides of a complimental face mat, whereby the mats are held in general vertical alignment. Certain of the fingers are of a gently curved configuration to frictionally hold edge portions of the face mats in spaced relationship for compression toward one another to accommodate settlement of the earthen formation, without bulging of the face mats. An L-shaped starter mat is engaged within a recess formed at the foot of the formation to provide an upstanding portion engaged with the lowermost is face mat to hold the mat in a generally vertical orientation. A tail is provided on the uppermost face mat for embedment within the backfill to cap the wall.
