Chain Drive is backed by my years of experience as a sewer rehabilitation contractor. I started in the sewer service business in 1978 and along the way got into sewer rehab with several major sliplining projects. I did my first pipebursting contract in 1992 (3200' - 8" sewer main, 6000' service laterals). After this and some other projects, based on what I learned, I built my own system using Chain Drive. Since then I've supplied pipebursting equipment to several other contractors. (See my Reference List).
