Mikael Creütz, M.Sc. (WSP- Sweden) specializes in Foundation Engineering and Rock Engineering. Mikael started his career as a technical consultant in 1995 which now means he has numerous years of experience related to design and execution of foundation works and rock works. For half of his career, Mikael has served as technical site supervisor, including major grouting works for cut-off walls in Stockholm, Sweden.
Mikael was responsible for implementing Scandinavian rock fissure grouting practice in Singapore for curtain grouting below secant pile and diaphragm walls for Bukit Panjang Station as a part of the new Down Town Line 2. In 2014 he was awarded the Swedish “Golden Pile” prize for his most significant contributions to the Swedish foundation industry, and since 2016 he has served as a grouting specialist for the Stockholm bypass project, which includes 55 km of rock tunneling.
Present grouting works includes rock fissure grouting for 14 km of hard rock TBM-tunneling below the city of Stockholm. The tunnel diameter is 5 m, and the maximum tunnel depth will be roughly 100 meters as well as grouting design the extension (PSU) of the existing SFR (Final Repository for Short-lived Radioactive Waste in Forsmark, Sweden. The new rock vaults in the extension will be about 120 m below the bottom of the sea.  
Mikael is involved in several rock fissure grouting research projects as well as he is writing papers about grouting works and presenting them around the world. He is a Board Member of the Swedish Association for Foundation Engineering (SAFE), where he is also involved in the education of contractors to become qualified in performing foundation works.
