Sewer Engineering – A Cycle that Makes Sense
Sewage network operators have already recognised the importance of systematic, electronically supported data management in the form of a cadastre of the sewage network and sewer pipes (GIS).
We help you to set up the cadastre using intelligent documentation material in whatever format is desired or possible:
- Inspection of the sewer pipes using CCTV cameras
- Manhole inspections
- Leak inspections and smoke testing
- Determination of inflow and infiltration
- Localisation of sewer pipes and manholes
- Entry of data into pipe cadastre
- Inspection of sewer sections from DN 40 to DN 2500
- IBAK systems MIDI, SIRIUS, TRITON und ARGUS
- House connection inspection system LISY
- 3-D system PANORAMO – virtual sewer sections
- 3-D system PANORAMO SI – virtual manholes
- Inspection of pressure pipes according to EN 805/EN 1671
- Inspection of sewer systems according to ÖNORM B 2503/EN 1610
- Use of Egger inspection systems
- Repair of cracked pipes
- Sleeve repair
- Lateral inflow
- Lateral outflow
- Sealing of holes in pipes
- DN 200 to DN 800
- Long life
- Rapid processing
- Sleeve repair
- Repair of isolated damage
- DN 150 to DN 700
- Repair of partial longitudinal and transverse cracks
- Repair of leaky or displaced sleeves
- Repair of holes
- DN 150 to DN 600
- DN 100 to DN 1200
- Egg-shaped pipes up to 90/135

It is also possible to repair damage resulting from age or biogenic sulphuric acid corrosion. The rehabilitation of a mineral surface is carried out by applying glass-fibre reinforced, sulphate-resistant, cement-based mortar on a cleaned surface.
Leaky sewer lines and manholes in groundwater are efficiently sealed using local injections of polyurethane or acrylic resins.
