	Landfill: Surface Water Collection and Removal System (SWCRS) Landfill capping are typically waterproofed using either a geomembrane or a geosynthetic clay liner (GCL). Infiltrating rainwater flowing over the liner drastically reduces the coefficient of friction at the soil/membrane interface producing, in addition, overpressures that can certainly promote slippage of the soil layer over the covering system. TENAX TENDRAIN geocomposites, properly installed on top of the waterproofing layer, shall be selected to reduce the amount of rainwater that might reach the liner interface. Surface water infiltrating through the cover soil will accumulate above the barrier layer and generate detrimental pore water pressure if it is not properly drained. Excessive head buildup due to inadequate drainage can cause catastrophic failure of the cover, numerous seepage-induced landfill slope failures have been recorded and analyzed to confirm this. TENAX TENDRAIN geocomposites and TENAX GNT provide the highest flow capacity among any geonet. The long-term in-soil transmissivity of TENAX TENDRAIN is in the order of 6 x 10-3 m2/s at a gradient of 0.1, and 4 x 10-3 m2/s at a gradient of 0.33. Long-term (10,000 hour) testing indicates that TENAX TENDRAIN maintains over 90% of its thickness when exposed to long-term compressive loads. This retained thickness maintains an open flow channel into which geotextiles are kept from intruding and rain water is free to flow.
	Stabilization of landslides Installation of geojute and TENAX TT geogrids. To restore a failed slope, the soil is often substituted with a different type of soil with superior geotechnical properties, significantly increasing material procurement costs and the environmental impact. In these cases, the use of TENAX TT SAMP geogrids allows the reconstruction of the slope by taking advantage of the on-site soil and assures a steep vegetated face. In this way the environmental impact is minimized and the reinforced slope is reintroduced back into its natural state without causing a negative environmental impact. To restore a landslide, it is necessary to remove the collapsed soil, to grade the backfill slope and compact the foundation and to reconstruct the slope in layers of well compacted soil and geogrids. Overall the slope can be more easily and much more rapidly restored since there are no foundations requiring excavation, no concrete formwork to set up, no reinforcement steel bars to align, and no time lost waiting for the cement to cure. The inclusion of TENAX TT SAMP geogrid layers will intersect the failure slip circle and impede the progressive sliding and deterioration of the rebuilt slope. Of extreme importance is the fact that a geogrid/reinforced slope has an intrinsic seismic resistance. Due to its superior elasto-plastic characteristics and to the damping effects conferred to the soil by the geogrids, the reinforced slope is not subject to failure during earthquakes, even when of considerable magnitude.
