The special civil and underground construction department in Linz was founded in 2001 with around ten employees. Since it was founded, the workforce at the Linz branch has grown to a large number of employees and has very successfully established the name Swietelsky in the special civil and underground construction sector.
More than 900 projects were successfully carried out between 2001 and 2015 and notable progress was made also in the area of product development.
Other fields of activity covered by the special civil and underground construction department in Linz include:
The innovative SWIENET system was patented in 2010 for temporary as well as permanent protection of excavation pits and slopes. The system consists of a galvanised steel braid with an underlying full-surface erosion protection mat. The system's anchoring and binding system can be adapted to any slope profile.
Advantages of SWIENET compared with conventional systems such as shotcrete include:
This type of deep foundation is primarily used in the inner city area in order to enclose excavation pits, construct road and railway buildings and foundation elements.
Whether cut-and-cover or top-down construction, space-saving and deformation-free construction would not be possible without diaphragm wall technology even in groundwater areas.
We offer a wide range of services in the area of anchoring, which are divided into the following sections:
If the soil conditions are bad, it is often necessary for the deep foundations to rely on single member piles/small drill piles/micro piles. Compared to site-mixed concrete piles with enormous machinery overhead, the above-mentioned piles are a competitive option with transferred loads of up to 1,000 kN possible.
