We are in the tennis and synthetic turf for almost 25 years. As a owner of the company I look forward to customer's satisfaction. Synthetic grass is a beauty but need to be refresh after few years. The sun , rain,fall, humidity, and debris will start to grow moss or mildew into the carpet if you do nothing to maintain your court. I invented a machine capable to remove, uncompact, lift the fiber upward and all that without removing the sand away from the tennis court...! I also have many invention I have accomplish over the years such as: Painter's friend, Wire twister, Winch winder, Portable milling, caulking removal tool, You can find all of those at: google , jomp 1951 or Youtube , jomp 1951
