Slinger Overview


Built tough and easy to operate, the Slinger is a contractor’s dream machine. Safe and simply designed, it applies cement linings to manholes with limited entry, reducing risk to personnel. Its aluminum housing allows for easy cleanup and utilizes sealed bearings for long life. This is a go-to product for rehabilitating wastewater structures like manholes.

The Slinger is a highly reliable product. Ken Novel, the president of XL Contracting, says he uses the machine every day. And Larry Morris, the owner of Morris and Associates, Inc. says the product has been helping his company for more than four years now. “As our business expands, we will definitely add an additional Slinger to our equipment fleet. We would not consider anything else,” he said.
