Who We Are

SG Geotechnika

SG Geotechnika a.s., as the oldest geotechnical consultancy in the Czech Republic, has a more than 90-year tradition. Until 2009, the company was known to business partners and professionals as Stavební Geologie - Geotechnika, a.s. From 30/6/2013 until 1/1/2017 the firm was part of ARCADIS, initially as ARCADIS Geotechnika a.s., and later under the name ARCADIS CZ a.s. On 1/ 1/ 2017, the company returned to its original name: SG Geotechnika a.s. The most recent milestone in the history of SG Geotechnika came on 1/ 9/ 2017, when ownership of the company was transferred to PURUM KRAFT a.s.

Today’s SG Geotechnika builds seamlessly upon the expertise of the first facility in the CR to provide engineering geology services, founded by Quido Záruba in 1926. Záruba was later awarded a professorship and presided over the IAEG. In 1930, Alois Myslivec, another Czech geologist of note, established the first Czechoslovak soil mechanics laboratory. The laboratory, which is the largest, best equipped facility of its kind in the Czech Republic, continues to be an important part of SG Geotechnika. The unique character, success, and strength of SG Geotechnika lies in the combination of knowledge and experience the company has acquired in its many years in the Czech marketplace, and its mastery of the latest European methodologies for preparing and managing large-scale engineering projects. It is the only company on the Czech market to offer its clients comprehensive solutions for geotechnical issues. It is also the only company in the Czech Republic with in-house capacity for geotechnical laboratory and field testing, including monitoring, geophysical and seismic measurements, 3D scanning, aerial mapping, and modelling. The company's focus is on consultancy, supervision, surveying, monitoring, environmental protection, and testing related to engineering construction projects, specifically in geotechnics, structural foundations, and underground construction. In addition, it manages engineering and environmental construction projects. SG Geotechnika operates in the Czech Republic and Slovakia, and employs more than 130 experts in its eight subsidiaries. SG Geotechnika a.s. Is actively involved in normalisation and methodology issues.
