The settlement speed decreases from 0.213 mm/day, after 9
days, to 0.061 mm/day after 22 days and further to 0.006
mm/day after 83 days. This led to the conclusion that
settlements are slowing down.

Proposed solutions
Continuous monitoring of building settlements and conducting
topographic readings at least every three months until the
constructions are stabilized.
Efficient vertical and horizontal systematization can be done
by making sidewalks, gradients for water discharge, ditches and
surface drains.
For stopping water infiltration in the foundation soil is
mandatory to check utility networks and repair them where is
necessary.

CONCLUSIONS
Difficult foundation soils are frequently found on sites located
in large urban areas.
Over time, a series of methods and techniques for improving
the difficult foundation soils were developed. The
implementation of this methods and techniques must take into
consideration the soil characteristics intercepted on the site.
In the case of loess soils that are improved using soil
cushions a good vertical and horizontal systematization is
required to drain the rainwater or the water from other surface
sources and to avoid the appearance of settlements.
