#### Abstract

Let a tile be defined as a non-empty subset of the integers. The concept of decomposable coverings as discussed by J. Pach and G. Toth can be extended to these integer tiles. In this context, a decomposable covering is defined as any covering of Z that can be partitioned into two distinct coverings of Z. Furthermore, we show that any finite integer tile can be used to construct a decomposable covering and provide bounds for the densities of such coverings. These results are expanded upon in the case of three-element integer tiles.
