Drilling is performed without any shocks, and is aided by outflow of cement and/or loam/cement grout from nozzles placed in appropriate points on the mixer. Upon reaching designed drilling depth, DSM columns are formed, and their diameters are most frequently within a range of 50 to 80 cm. Properly rotated and raised mixers provide uniform mixing of grout and soil. Composition and amount of grout being pumped in is adjusted to projected properties of the mixture of soil and cement, based on designed function of DSM diaphragm/column.
