Permanent and semi-permanent loads spread over large areas
Remediation of a polluted
Parking lots, storage
areas and artificial basins or landfills at times are constructed
over soils with poor mechanical characteristics. Under these circumstances,
differential and localized settlement caused by the presence of
permanent loads, represent the principal cause of settlement and
breakdown in the soil and in the base’s structure.
In such circumstances,
the correct use of a TENAX VDR drainage strip together with a rigid
basal structure reinforced by TENAX LBO geogrids or TENAX 3D Grids, gives the
degree of consolidation required by the project designer within
the desired timeframe.
The permanent load of the waste dumped in a
landfill can produce settlements of the subgrade
and consequently high stresses in the waterproofing
layers. The permanent load of the water in a
reservoir may lead to premature failure of the
waterproofing layers due to excessive settlements
of the soft subgrade.
Several layers of TENAX bi-oriented geogrids
significantly improve the bearing capacity of
permanently loaded areas, like landfills and water
reservoirs, thus greatly reducing settlements.
1. Soft Soil
2. Waste material
3. Tensile stresses
4. Soil cracking
7. TENAX bi-oriented geogrids
TENAX geosynthetics prevent localized failures and
distribute the load over a larger area: as a result
the potential failure surface is deepened and the
bearing capacity is increased.

2. Granular fill

5. TENAX geocomposite
6. Enlarged shear resistant surface
