Open construction
You benefit from the "know how" of our experts
First, we use state-of-the-art camera technology to check the current condition and determine the scope of any necessary renovation measures. In most cases, the problem can be remedied by means of closed remediation, but closed construction may not be the most economical or effective long-term approach for every finding.
In some cases, the damage may be so complex or severe that open construction and conventional civil engineering are necessary. In this case, our open remediation experts are at your disposal. In the event of gradual subsidence, e.g. in the case of a washed-out pipe caused by a leak in the pipe, it is advantageous to rectify the cause of the damage using the open trench method so that the renewed sewer once again meets the structural requirements. Please contact us so that we can draw up a renovation concept with you.
Sewer renovation in Pohlheim
Sewer damage detected by our TV systems can also be repaired without civil engineering work if the damage pattern and the analysis allow this. We use a pipe lining process for this purpose.
This process involves a woven synthetic fiber hose, which is usually impregnated with 2-component resins and cured in the old sewer as a "pipe-in-pipe system".
Hose fittings soaked in resin or cut-to-size fiberglass mats are pressed into the leaking or cracked areas using air pressure or inverted using temperature-controlled inflow water.
Thanks to this modern repair method, old sewers can often be put back into operation after just a few hours. The materials used here are exclusively tested and DIBT-approved construction materials and are installed in accordance with the manufacturer's specifications.
Creation of head holes
- Head hole creation for the closed sewer rehabilitation incl. surface demolition
Shaft structures and cisterns:
- Demolition of existing shaft structures
- New construction of manhole structures made of concrete and plastic (also in combination with the installation of backflow protection)
- New construction/installation of cisterns and rainwater drainage systems
Sewer renovation using the open construction method
- New construction of pipes and sewers in the property drainage area
- Separation of wastewater and rainwater drainage for backwater prevention in combination with backwater protection concept
- Ancillary services: Earthworks, paving work, disposal, coordination of any subcontractors that may become necessary
