Time (Days)

Moisture reduction with different heights
1. A draining phase, during which water is drained towards geotextil. This phase
leads to a quick water loss and lasts about 1 day.
2. A phase where evaporation is relatively intense (until 15 days) and comes to a
quasi-linear water loss.
3. A last phase where water loss is very slow (from 15 days).
