A brief overview about geosynthetics in landfills

Abstract

Liners are impermeable barriers used in landfills to avoid or decrease the flux of leachate to protect, by the way, the environmental. Many ways of barriers are used: soil with low hydraulic conductivity, compacted soils, synthetic materials like geomembranes, geotextiles, geosynthetics clay liners and/or a combination from all those. This paper presents some considerations about landfills and the use of geosynthetics in the composition of the liners which are used in both cover and basal systems to maintenance of the flux.
