Sealing system for service entries

Universal, economical
sealing system for bore-
holes and service entries
in buildings with wall
thicknesses > 100 mm


For the subsequent gas and watertight sealing of cable channels and service entries in buildings configured with optical and electrical telecommunication cables and/or medium pipes in the telecommunication sector.


For configurations with more than 2 cables, the cables are wrapped in sealing tape. The sealing element is inserted in the borehole or service entry and inflated up to the pressure given in WO 05-3 via the tyre valve. Inflation is with air (CO2-neutral) and therefore environmentally friendly.


On inflation, the sealing element expands to fill the area to be sealed. The element can be removed by simply deflating it via the valve.


Specially developed materials prevent permanent adhesion of the element to its surroundings, guaranteeing fast, easy removal.


Sealing width 100 mm for wall thicknesses > 100 mm.


Available for boreholes/ service entries in buildings Ø 50 mm to 150 mm
