Location: Wengistrasse 30, 8004 Zurich

The Challenge (Initial Situation): As part of the renovation and vertical extension (addition of storeys) of the existing building, it was imperative to guarantee the structural stability against the new loads.

The SoilTec Solution: We carried out a preventive reinforcement of the soil's load-bearing capacity via injections. This intervention prepared the ground to support significantly higher loads without compromising the building's integrity.

Location: Silbernstrasse 9, 8953 Dietikon

The Challenge (Initial Situation): Constructing a new elevator pit required excavation within the groundwater table. The critical task was to seal the deep-set steel pipes designed to house the hydraulic cylinders against water ingress.

The SoilTec Solution: We executed a watertight sealing of the excavation. By creating a sealing slab and walls using injection technology, we ensured a completely dry environment for the complex lift installation.

Client: Coop Real Estate, Silbernstrasse 1, 8953 Dietikon.

Location: Buholzstrasse 32, 6032 Emmen

The Challenge (Initial Situation): Connecting a new tunnel to the existing sewer canal required cutting through a sheet pile wall located below the groundwater table. The annular space between the wall and the pipe had to be sealed to prevent water ingress.

The SoilTec Solution: We executed a watertight sealing of the annular space. Our injection successfully blocked the groundwater, allowing the sheet pile wall to be opened safely for the construction of the connection tunnel.
