Packers for trenchless rehabilitation
Wunderplug packers are designed for trenchless pipe rehabilitation, typically to install resin-impregnated sleeves (CIPP / liner) on localised sections. Unlike a standard plug that simply isolates a section, the packer supports the liner in place during curing. They are used to repair cracks, faulty joints or localised infiltrations without excavation. Since every job is unique, we define the right configuration together for your site.

Mechanical pipe plugs
Mechanical pipe plugs seal by clamping — usually axial compression of a gasket against the pipe wall — without compressed air. They are the right choice when a pneumatic plug isn't suitable: long-duration shutoffs, no on-site air supply, or specific constraints tied to the fluid or environment. A robust, self-contained solution, well suited to permanent or semi-permanent isolation points. Contact us to work out the configuration that fits your need.
