EMBANKMENT BASE
REINFORCEMENT

Embankments constructed on soft foundation soils are often difficult to construct. Problems such as local bearing failure caused by heavy construction equipment is common. Embankments constructed on soft foundation have a tendency to spread laterally, causing shear stresses at the base of the embankment, resulting in failure.

​

The geosynthetics placed at the subgrade/embankment interface can be stabilized the subgrade by maintaining the initial fill thickness through its separation function. When the overburden pressure, due to the height of the embankment, is sufficient to mobilize lateral strains within the structure, the geosynthetics (with high tensile strength) provide additional tensile resistance forces to ensure the stability of the embankment.
