Bridges, water and wastewater plants, district-heating and utility networks have to be maintained while in service – shutdowns are costly, often safety-critical and affect the public.
HSOS brings the workshop to the asset: composite repairs to ISO 24817 on pipes, tanks and structures, pipe freezing for valve changes without interrupting supply, hot tapping on live utility lines, bolt-tensioning of structural and flanged connections, and mobile machining of large components.
Experience: water and wastewater treatment plants, district-heating networks, road and rail bridges, locks and hydraulic structures, municipal utilities.
Challenges
- ▸Supply must stay on – very limited shutdown windows
- ▸Safety-critical, publicly used structures
- ▸Ageing assets with incomplete documentation
- ▸Restricted access, work at height and in confined spaces
- ▸Weather exposure and mixed materials (steel, cast iron, concrete)
Our experience
- ✓Composite reinforcement and repair of pipes, tanks and structures to ISO 24817 and ASME PCC-2
- ✓Pipe freezing on water and utility mains for valve changes without interruption
- ✓Hot tapping and line stops on live district-heating and utility lines
- ✓Bolt-tensioning with documented preload on structural and flanged connections
- ✓On-site machining and line boring of bearings on locks, movable bridges and large valves
- ✓Leak sealing under operation, 24/7 emergency response

FAQ
Work without a shutdown?
Yes – pipe freezing, hot tapping and leak sealing allow interventions while in service, without interrupting supply.
Is composite repair permanent?
Correctly designed to ISO 24817, yes – engineered for 20+ years, documented and verified.
Work at height and in confined spaces?
Yes, with SCC/VCA-trained crews and suitable equipment; scaffolding or MEWP as required.
How fast on site?
Usually within 4–8 hours in the DACH region and Benelux, up to 24 hours Europe-wide.
