The flexibility of the Tandem Modular Block system allows interconnection of structural units by using their tenon and mortise features. This has the advantage of being able to build stronger walls by adding units in the back. The Tandem Modular Block has three different veneer face styles. This makes it have better stability during installation.

The Modular Block only comes in one color which is grey. This is shown in the picture above and below as a reference.
