  About Us





Unlike other interlocking block systems there are only two blocks: the combination stretcher-corner-end block and the half block. Only one mold is necessary! All the mold cavities make the combination stretcher-corner block, and when needed, one of the cavities is equipped with an insert for making half blocks.
