for the construction of a parking lot.

 

 

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 landfills and artificial basins, localized settlement can also cause the rupture of the impermeable basal layers, leading to very serious environmental consequences.

Bioriented TENAX LBO and TENAX 3D Grids MS geogrids reinforce and increase the stiffness at the base of areas having permanent loads; the tensile forces and the lateral confinement provided by the geogrids allows a more uniform load distribution and, consequentially, a higher bearing capacity.

The time required for the completion of the primary consolidation phase is often very long and incompatible with the operating needs for which the structure is designed.

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 result is the reduction or even the elimination of the differential and localized settlement.

The permanent load of the waste dumped in a landfill and the load of water in a reservoir
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.

layers of geogrids to improve the bearing capacity of loaded areas
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.

TENAX geosynthetics prevent localized failures and distribute the load over a larger area
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.
