The lineup of the aging pipeline rehabilitation method "KanaSlip Method" has increased!
The "KanaSlip method" is an extremely simple and economical trenchless pipe rehabilitation method that involves inserting factory-produced self-supporting rehabilitation pipes directly into aging sewer pipelines and performing pipe end treatment. The self-supporting rehabilitation pipes excel in seismic resistance, load-bearing capacity, workability, and cost-effectiveness, and they are also eligible for subsidies. In March of this year, Φ400, Φ450, Φ500, and Φ600 were added to the certification, further enhancing the lineup. We have also updated our catalog, so please feel free to download it.
