Pipe Rehabilitation Test Results
The following independent tests, conducted by leading universities, testing organizations and engineering firms, have consistently found that Insituform's products typically exceed our own design expectations and perform substantially better than most other products. Their analysis, as the study results demonstrate, have helped make our technologies the benchmark by which other rehabilitation products are measured.
