Water saturation of soils in the area of foundations is accompanied by a deterioration in their bearing capacity and is often detected only with the appearance of the first signs of deformation. Effective monitoring of soil conditions helps reduce escalating damage. For this purpose, a variant of dynamic penetration was developed and applied, which made it possible to establish a fivefold reduction in the resistance of soils to indenter penetration in the water-saturated zone in comparison with their natural state. The approach provides rapid mapping of the state of the soil mass in areas of expected soaking, for example, in the area of backfilling of foundations. The results are applicable for monitoring soil soaking in technogenic conditions and are of interest to a wide range of specialists in the field of construction.
