Superficial structural foundations
When designing shallow foundations it is necessary to:
- Guarantee an adequate safety factor to prevent puncturing caused by insufficient bearing capacity;
- Reduce settlement, and in particular differential settlement,
within acceptable limits.
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.
Products
 A reinforced soil wall can profit of the stabilisation provided by TENAX bi-oriented geogrids against bearing capacity failure.  TENAX bi-oriented geogrids distribute the load over a wider area and prevent punching failure within the reinforced fill: in this way the failure surface is enlarged and deepened, with a resulting increase in bearing capacity.
