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 SAMP and TENAX 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 SAMP geogrids, 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.
