The space behind the wall is occupied by a barrier that is constructed out of gravel and lined with fabric. The fabric prevents the empty spaces in the gravel from becoming clogged with silt.

Polyester and vinyl are the two types of fabric that are most frequently used for the construction of retaining walls.

Polyester is by far the most popular material used for the fabric, however despite its widespread use, it also has the lowest durability rating.
