Go to old websiteTelescopic seal that stops groundwater infiltration between extension rings, surface boxes and manhole cones, regardless of the material in the manhole.
The telescopic seal seals joints in the manhole and prevents groundwater from infiltrating wastewater and stormwater systems. It is fitted between, for example, the manhole cone, extension rings and surface box, where movement and irregularities would otherwise create leak paths. Thanks to the flexible construction and telescopic effect, one and the same product fits many different manholes, and the material of the manhole, extension ring or surface box makes no difference. The seal is available from DN 400 to DN 1000, with a span that accommodates dimensional deviations, and in four length variants from L to XXXL that bridge gaps of just over 600 mm. If more length is needed, several telescopic seals can be connected in series. Installation is quick and simple and can be carried out with a dedicated installation and removal tool.
