Lining Observations

Resin Missing from Laminate (Composite)

Possible cause of damage

  • Resin impregnation not accurate

  • Insufficient vacuum during resin impregnation

  • Too high inversion speed

  • Too low inflation pressure

  • Strong styrene evaporation during curing

  • Resin leakage due to damaged external membrane / coating


  • Static assumptions no longer apply

  • Weakening of the CIPP liner

  • Effects on the high-pressure cleaning resistance

  • Leak tightness of the CIPP liner not guaranteed
