Foundation engineering
Implenia is at home in all areas of the broadly diversified foundation engineering discipline and has decades of experience. We are the number one in Switzerland in this challenging sector and our expertise enables us to offer these services abroad as well. With the help of modern, high performance machinery, our proven specialists are able to overcome the toughest of challenges.
Large-diameter drilling
In situ concrete piles (cased or uncased), installed with rotary boring machines or grabbing devices, form the basis for pile foundations with a diameter of between 700 and 2,500 mm. Drilling for large filter wells aids the water supply or supports major construction projects by reducing groundwater levels over a large area (diameter 800 to 1,800 mm). We also carry out vertical shaft drilling for horizontal filter well systems.
Displacement piles
We are your partner for low-noise full or partial displacement piles with diameters of between 420 and 620 mm and for vibration-free installation of piles in displacable ground for pile loads of up to 5,000 kN.
Excavation bracing
Bored pile, diaphragm and soldier pile walls as well as soil nailing are used for excavation bracing. Thanks to our longstanding experience with diaphragm walls, our projects include not only very successful excavations but also work on sealing dams, landfills and tank systems.
Small-diameter drilling
Be it prestressed anchors for temporary or permanent anchoring of buildings, micro-piles for transferring what can be enormous loads to the load-bearing subsoil, soil nailing for securing excavations, strengthening the subsoil by means of jetting or injection or manufacturing small filter wells: Implenia guarantees that your project will be carried out professionally and in compliance with technical requirements.
Dewatering
Planning and executing dewatering concepts is one of our core competencies. From open dewatering or vacuum reduction (wellpointing) to reducing the groundwater level with filter wells, we guarantee that your construction will be completed successfully.
Exploration drilling
We conduct geological, geotechnical, hydrological and residual-waste-specific soil explorations for your project. With our comprehensive fleet of machinery, we can carry out exploration drilling even in terrain that is difficult to access.
Vibro-flotation
We can also turn fine-grained soils such as silt and clay into load-bearing ground. We have been using vibro-flotation to compact soils for buildings which are susceptible to subsidence or situated on highly granular subsoils for over 70 years.
Complete excavation solutions
Thanks to our experience in all areas of the foundation engineering sector and above all in excavation security, we offer comprehensive solutions for your entire excavation project.
