Repair Types: Pipes

Typical problems encountered with sewer or stormwater pipes include:

• Intrusions
  
• Encrustation
  
• Blockages due to tree roots, debris and even concrete
  
• Cracks
  
• Leaking or broken/displaced joints
  
• Disused junctions
  
• Bulges and localised irregularities
  
• Short ends
  
• Poorly cut junction re-openings
  
• Lateral connections blocked
  
• Failed liners causing blockages
  
• Pipe lifting holes left unplugged – risk of soil ingress and surface subsidence
  
• Corrosion
  
• Breaks/fractures
  
• Leaks

Structures Including Manholes & Culverts

Typical problems encountered with sewer or stormwater related structures include:

• Gas attack of concrete
  
• Concrete degeneration
  
• Infiltration gushes
  
• Groundwater infiltration
  
• Leaks
  
• Structural collapse through corrosion
  
• Cracks
