Thompson Building Materials’ used bricks — salvaged from old buildings and hardscape areas — are just as durable as brick manufactured today. The inventory is ever-changing so it is important to note that selection should be done onsite at a Thompson yard that carries used brick inventory. Within Thompson’s inventory of used bricks you may find wire-cut brick cut from a long bar of extruded clay by a set of wires and Simons brick and sand-molded brick. Both Simons and sand-molded brick use sand to coat the brick to prevent sticking to the mold.
