Landscape Architects seem to always be in need of good looking materials for our models.  One of the areas that is difficult is finding look looking bricks for either our ground surfaces or realistic ones for wall surfaces.  Here are two interesting solutions.

Once could make your own with Bricks’n’Tiles.  This standalone program can help you create bricks from two images (one for the brick and the other for the mortar).  With right input, this program can be used to create any repetitive surfaces like floor boards, concrete…

One can donate or buy another program they offer to show your appreciation for this software.

If you do not want to build it from scratch, I would recommend Unilock’s bricks in the 3D warehouse.  Many colors are available.  Although it may not be a perfect color match to the final product, it is very close.
