Based on the Italian Building Code
- T1 = Flat surface; isolated slopes and cliffs with average slope angle i < 15°
- T2 = Slopes with i > 15°
- T3 = Ridges with crest width significantly less than the base width and 15° < i < 30°
- T4 = Ridges with crest width significantly less than the base width and i > 30°
Ground type EC8
