Application of geosynthetics for reinforcement of flood protection embankments

In Croatia, a large number of flood protection embankments were constructed many decades ago and their deterioration is inevitable. These embankments are subjected to series of factors making them prone to different types of failures. Also, a lack of vision for their remediation led to many problems in past few years, such as large-scale flooding events. In the same time, mandatory design standards, which ensure overall stability of embankments, are becoming stricter making the remediation procedure more complex. Designers need to cope with investor's constant aspiration to keep the remediation costs as low as possible. In order to satisfy strict standards and investor’s mentioned aspiration, a relative modern solution for reinforcement of embankments is shown in this paper. This solution comprises of application of geosynthetics where, among vast range of types, geogrids are most often used for reinforcement of flood protection embankments. Main advantage of geogrids is in increasing safety aspects, extending embankment work life and potentially reducing overall remediation cost through reduction of earthworks. Characteristics of geogrids, as well as mechanisms, which drive their behaviour through interaction with soil materials, are also presented in paper. Other than reinforcement, geosynthetics can be efficiently used in embankments by means of material separation, filtration, drainage or to ensure its impermeability.
