Manhole rehabilitation with the PREDL - Flexliner system.
Sewer infrastructure (shafts, chambers, manholes, wet wells,) are permanently susceptible to corrosion.  Aggressive material not only destroys the sewage channel area, but also attacks rising shaft components such as rings, cones and ladder rungs.
PREDL works with different remediation methods depending on the local conditions:

• Renovation with CORPROTECT lining;
• Renovation with PREDL-GFK components;
• Restoration with PREDL-Flexliner;
• Precise recording of infrastructure data and factory engineered recommendations aided by laser-based surveying using the most modern laser technology.​
