Sanierung von Kanalanschlüssen in der Hamburger Altstadt

Sanierung von 12 Hausanschlüssen (Nennweite DN 150) in einem dicht bebauten Gebiet aus dem 19. Jahrhundert.

Die Arbeiten wurden ohne Zugang zu den Kellern der Wohngebäude, ohne Aufgrabungen im Umfeld und ohne Abstimmung mit den Anwohnern durchgeführt.

Mithilfe der SP technology!RES konnte die Dichtheit der Rohrleitungen wiederhergestellt und dabei die historische Infrastruktur der Stadt bewahrt werden.

Key parameters:
Diameter (nominal) DN100
Wall thickness after polymerization 4 mm
Length (available options) 3 m, 6 m, 9 m, 12 m
Base material Polyester (PES)
Resin Type Heat-cured (unsaturated polyester)
Polymerization time at 80°C 60 minutes
Max. operating temperature +50°C (short-term up to +80°C)
Stiffness class SN4 (on request SN8)

What did the customer encounter?

Hamburg’s historic center is a densely built—up area with limited access to utilities. Cast-iron sewer outlets, laid more than 70 years ago, have fallen into disrepair: multiple fistulas, cracks and leak-proof joints.

The main problems:

  • Access to the pipes is possible only through the basements of residential buildings
    (private property)
  • Excavations in the surrounding areas required coordination with the Department of
    Architecture (Monuments)
  • Residents opposed noisy work and the dismantling of coverings
  • The traditional repair method required the relocation of residents for the duration of
    the work.
  • The city’s budget was limited

Preparatory stage

The first stage was a TV inspection of all 12 issues. This made it possible to accurately determine the damage sites, pipe diameters and the length of the areas requiring rehabilitation. At the same time, the pipes were hydrodynamically cleaned of deposits.
