Manhole inspection and rehabilitation
Professional solutions for drainage systems
Reliable manhole inspection is the basis for the safe operation of sewers, drainage systems and structures. Inspection chambers play a central role here, as they provide access to the sewer network and must be inspected regularly. Early manhole surveys and condition inspections allow damage to be detected in good time, targeted renovation work to be planned and high follow-up costs to be avoided.
State-of-the-art technology for precise manhole inspections
Our experts use high-resolution 3D cameras and scanners to record the entire shaft in a single vertical inspection. This creates a complete, three-dimensional model that makes even the smallest damage visible. Thanks to the detailed evaluation of the condition data - for example in accordance with EN 13508-2 - you receive standard-compliant documentation that can be used with legal certainty for building inspections and expert reports.
Even manholes that are not directly accessible with the inspection vehicle can be easily inspected using special additional equipment. This ensures that every manhole is reliably inspected - regardless of its location or accessibility.
Scope of our manhole inspection and rehabilitation services:
- Inspection and surveying from DN 300 for manholes and structures
- Shaft access up to 80 meters deep possible
- Cost efficiency through fast and precise condition surveys
- Manhole renovation according to current technical standards
- Digital 3D models for transparent damage documentation

Manhole renovation
Groundwater ingress, aggressive media or biogenic sulphur corrosion stress manholes and threaten the stability of concrete manholes. As experts in manhole rehabilitation, we are always at your side with our efficient rehabilitation measures. We carry out renovations in accordance with DIN 1610/DW-M 143-6/143-17. We always offer high quality, which our experts guarantee through solid manual work, the use of special materials and state-of-the-art tools.
To rehabilitate your manholes as quickly, permanently and cost-effectively as possible, our experts use a variety of options:
- Shaft cleaning with high-pressure water, solid blasting with sand or granules
- Substrate pre-treatment (adhesion primer) and mortar coating according to DIN 19573
- GRP lining with hand laminate or a polyurethane coating, with these processes we subsequently make your shaft liquid-tight.
If required, channels and berms are also rebuilt or reprofiled in both mortar and clinker construction methods.
You can expect this service from our manhole renovation:
- Rehabilitation in accessible sewers from DN 800
- Resin or mortar liner connections
- Removal and installation of climbing aids
- Crack repair
- Separator rehabilitation
All materials used have DIBT approval and thus meet the high standards required for flawless operability of your duct and manhole systems.
