Armater has been specially designed for use on sub-bases which do not generally allow the growth of vegetation due to their geological properties. Slag heaps and rocky slopes are examples of this kind of sub-base, upon which a 10 cm thick layer of soil can be applied into Armater to form the basis for the development of vegetation.

In such cases, the honeycomb structure of Armater allows the mat to be filled with topsoil, providing a lasting grip in the cascading geocells.

A further major application of Armater is on slopes where the topsoil would erode, if no corresponding measures were taken to combat erosion.
