MRT Phase II construction in Jakarta, Indonesia
Drilling Fluids for Diaphragm Walls
Jakarta, Indoneisa
The second phase of the Jakarta MRT construction started in June 2020, after a long delay due to the pandemic. Phase 2 comprised a 2.8-kilometer underground tunnel leading through Indonesia’s capital city. We are proud to be part of the construction of 152 diaphragm walls at Sarinah station as drilling mud advisor team and supplier. The installation of the slurry trenches involves extracting a trench while simultaneously keeping heavy viscous slurry (bentonite) filling the excavation to provide lateral pressure that must be at least be equal to or greater than the lateral pressure of the trench walls.
Our mud expert team in Indonesia helped to choose the must suitable bentonite drilling mud and additional polymer to manage the sandy and saltwater contaminated soil profile.
