Solutions for trenchless pipe rehabilitation

Trenchless pipe rehabilitation with lineTEC – Why rehabilitate?

With over 20 years of experience, lineTEC, a brand of Vereinigte Filzfabriken AG (VFG), offers certified pipe lining systems for the rehabilitation of defective pipelines. Our products combine state-of-the-art technologies with precisely formulated resins and specially developed liners for a wide range of applications. Many installed pipes have long exceeded their service life. Even if they still appear functional, a camera inspection often reveals damage such as:
  • Leaky joints
  • Ingrown roots
  • cracks
Signs of pipe damage can include:
  • Frequent constipation
  • Damp masonry
  • Cracks or subsidence in the base plate
If detected early, leaking pipes can be repaired quickly and relatively inexpensively. This helps to avoid lengthy downtimes or costly follow-up expenses.
