Geomorphology – Geology • Clayey-marl formations, with scattered intercalations of sandy- marl • The presence of the sand layers in combination with the inclination of the layers acts as a water bank, creating confined water masses of hihigh h capacitity and hdhydros ttitatic pressure • During slope excavation, intense water flow was monitored from the sand layers of the “champagne” effect type and creation of mudflow

Our Services • Investigation of the in-situ geotechnical conditions of the subbase • Qualitative classification of the subbase according to UIC719R 2008 • Selection of the required subbase reinforcement according to UIC719R 2008 • Appropriate reinforcement of the subbase with geogrids and soil replacement in sections of the project where the minimum requirements of the UIC719R 2008 are not met.
