The refurbishment of building connections can be performed as a trenchless construction using the membrane injection system (existing or new building). Accessibility for an open construction is not possible or not desired. Reliable sealing using a 2-component resin can also be ensured under unfavourable conditions. A trenchless house connection is suitable for virtually all wall construction materials after making a core drill hole of between 99 mm and 103 mm.

Refurbishment of building connections in existing buildings. Difficult conditions due to different basement constructions and construction materials. Making a core drill hole of99-103 mm.

Adaptation of the building entry to the on-site conditions: cutting to length and adaptation to wall thickness. Sealing is achieved through injection of a 2-component resin via a filling hose.

Following creation of an empty conduit route (DA 63) using a soil displacement rocket, the building entry is pushed into the core drill hole via the driving pipe.

Inspection opening on outside of building: the completely escaped/ partially exuded resin under the shield enables the integration of pre-existing surface sealing where applicable.
