Description

In areas saturated with groundwater, water intrusion can adversely affect or even wash out resin curing. The Preliner forms a waterproof barrier that keeps the liner dry during the critical installation process. This is not only a technical advantage, but often a hard requirement: according to DIBt guidelines, the use of a Preliner in groundwater zones is mandatory to ensure a quality renovation.

There are situations where you don't want the liner to permanently adhere to the wall of the old pipe, such as with specific materials or when the liner needs to be removable later. In such cases, the Preliner acts as a separation layer. Thanks to the smooth PE material, the liner slides smoothly into place, reducing friction during inversion and minimizing the risk of damage.

Despite its protective function, the Preliner is extremely thin and flexible. With a thickness of only 150 µm, it takes up virtually no space in the pipe. The liner is designed to pass bends of up to 90° without problem without creasing or blocking the liner's passage. This makes it suitable for virtually any type of indoor sewer or ground pipe within the DN 100 to DN 300 range.
