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.
