Firstly, we clean the line section to be checked with our high-pressure flushing process. Then the ends are blocked by inflatable pillows and the tightness is determined with water or air pressure according to the respective DIN regulations. If the sewer is tight, you will receive a detailed test report from us and legal proof to submit to the public authority, insurance, etc. If pipe sections are leaky and possibly contaminated with soil and groundwater, we will discuss the next steps with you. A camera inspection is often recommended to determine the extent of the damage. Should it be necessary or sensible to repair the damage, we will create a tailor-made, sustainable solution for your complete sewer rehabilitation concept.
