Q.: I attended a home-improvement exposition where I saw a demonstration of a piece of equipment that can engrave brick, cobblestone or other designs in existing concrete sidewalks and driveways. I asked who made the machine but couldn't get an answer. Can you help me? The machine looked like a large lawnmower.
A.: The machine is manufactured by Engrave-A-Crete Inc., 1390-G Commerce Blvd., Sarasota, FL 34243 (phone: 800-884-2114).
