Trenchless Engineering Group Inc. provides products and services throughout North America to a broad range of industries including horizontal directional drilling, foundation drilling, slurry wall and tunnel boring machine. We contract with several medium and small mud companies to provide services to their customers, as well as our own client base. Headquartered in Dallas Texas, we have an experienced crew on board that brings years of experience to the table. We do not favor any particular product brand, as all of our staff have worked with most major brands, and minor brands. We offer a range of services to cover everything from pre-bidding to long term consultation and mud schools. With projects being added to our portfolio every week, we have the experienced staff you need, and can get the job done. Trenchless Engineering Group is a wholly owned subsidiary of Cottle Holdings Inc.
