Placing one or more layers of bioriented TENAX geogrids beneath the foundation can augment the bearing capacity of shallow foundations. In fact geogrids allow for uniform foundation settlement, minimizing the risk of differential settlement and effectively limiting horizontal soil deformation.
The confining action of the soil beneath the foundation prevents localized rupture or puncturing which can cause the foundations to sink. The surface on which global rupture failure occurs is deepened and enlarged by the geogrids and for this reason the soil shear strength and bearing capacity are increased considerably.
