Frequently asked questions
During rehabilitation, damaged pipes are repaired either selectively or over their entire surface, depending on their condition. Using the inliner sewer method, a resin-impregnated tube is pulled into the pipe and cured with light. The result: a new, leak-proof inner lining.
If a manhole is damaged, the walls, berms or channels may be cracked or worn. During a manhole repair, this damage is repaired and the manhole is coated with special materials to protect it in the long term. This extends its service life and restores its function. Regular maintenance can help to detect major damage at an early stage. Contact us for an individual consultation.
You need a backflow flap if rooms in your house are below the backflow level – e.g. basements or lower-lying bathrooms. In heavy rain, the public sewer network may be overloaded. Without a backflow flap, the wastewater then pushes back into the house – often via the toilet, shower or floor drains. A functioning backflow flap protects the home from exactly this kind of flooding. Important: It must be maintained regularly, otherwise you risk losing your insurance cover in the event of damage.
The high-pressure water jet robot ensures particularly thorough and gentle cleaning before sewer rehabilitation. Even stubborn deposits such as concrete residue, bitumen, roots or incrustations are efficiently removed – without damaging pipes or lines.
The robot can be individually adjusted depending on the pipe material and degree of soiling. The integrated camera monitoring ensures full control during operation. The technology is used for pipe diameters from DN 100 to DN 1500.
