Manhole inspection and rehabilitation
The inspection shafts are also a part of the drainage system and must be regularly inspected and tested. With the help of high-resolution cameras (3D scanners), it is possible to digitally record the entire manhole in a single vertical inspection. In this way, a three-dimensional model is created and we do not miss a single millimeter of your manhole. The detailed evaluation of the condition data, e.g. according to EN13508-2, takes place after the recording. Even if shafts cannot be approached directly with the vehicle, we have the appropriate additional equipment to inspect these shafts as well.
Our experts carry out shaft inspections and shaft surveys for standard layers and structures from DN 300. The shafts can be inspected to depths of up to 80 metres during a shaft inspection. Thanks to the modern technology, you save time and costs, both for building inspections and for condition checks.

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.
