Single building entries - trenchless construction

Single building entries - trenchless construction

In addition to the standard open construction, in many cases it is possible to create a building connection by pulling through an empty conduit, without the need for major groundwork. Our single building entries for trenchless construction do not require an installation trench on the outside of the building. The building entries can be installed entirely from the inside of the building, making them ideal for use if the building connection has been built over or is difficult to access.

Like our open construction single building entries, with our trenchless installation method, we also guarantee that the building entry will subsequently benefit from professional sealing.
