Sewer Rehabilitation

without costly digging up

Damage repair is now also possible in a closed construction method without extensive digging. Short liners are used for this. This means that the damaged area is lined from the inside with a special resin-impregnated glass fibre mat.

Procedure of a short liner rehabilitation

  • Preliminary cleaning of the pipe
  • Check of the extent of damage with TV inspection
  • TV inspection to document the actual condition and exact measurement of the damaged area
  • Application of a resin-coated glass-fibre mat on an installation device (packer), positioning of the packer under camera observation
  • Proof of repair success by TV inspection
