According to the AwSV, special designs are prescribed on manhole chucks, which describe, for example, penetrations on concrete structures to plastic pipelines. As a rule, here are required so-called wall collars. By means of the SABUG source sealing systems, components are provided in accordance with the pipe dimensions, which reliably seal against pressing water both from the outside and from the inside. Appropriate testing with regard to LAU and JGS resistance is, of course, available.
