Loess soils, which occupies much of central Argentina, is characterized by its high sensitivity to change in moisture. This condition categorized loess structure as internally unstable soil. Despite this natural condition, silts derived from loess are frequently used as material in roads and hydraulics constructions. In filtration processes, the soil should be shielded from erosion phenomena. The filter must have a particle size consistent with the ground to protect. In particular, sandy silts can be affected by phenomena of suffusion, or internal instability of the soil structure. The filter must control the loss of material and ensure the stability of flow. The present study shows the experimental results of flow applied to loessial silts, with low compaction. Tests have been conducted using filtration columns that simulate the soil-filter-drain. The test methodology applied aims to follow the research lines of similar studies worldwide. Studies have focused on analyzing the influence of variables such as degree of compaction, hydraulic gradient and composition of the filter material. The results obtained allow recommendations with reference to construction systems to be applied and the composition of the filter in order to properly control the suffusion.
