I have been involved with this type of work for 30 years and have never seen the manhole lid and frame, after being raised, not create a small bump in roadway. Your product and workmanship has proved it can be placed without the bump. I want you to know that we are very pleased with the quality of the manhole leveling system and service your company provided. We would recommend your company to others because of the wonderful service and product you provided.
