TVD is certified to install Pipe Robo-Tec Internal Pipe Seals from 8” to 24”
Pipe Robo-Tec is a mechanical, continuous mounting stainless steel sealing system designed for non-accessible piping systems. They are designed to eliminate leaks
caused by longitudinal cracks, holes, leaking seals and offset joints. TVD crews install
Pipe Robo-Tec seals using standard remote controlled CCTV equipment and an inflation bladder. This process ensures a quick installation and minimal surface disruption.
TVD utilizes CCCP equipment, as well as spray and trowel application methods to structurally restore and protect pipe ranging form 36” and up. The CCCP process is one of the most cost-effective methods of trenchless technology and eliminates the need to dig and replace the old pipes.
TVD is trained to install Interfit Lateral Connection Seals, the only true one-piece full main wrap to address I&I at the sewer main connection.
