Many urban sites are former landfilms, industrial yards, or brownfields that pose contamination risks. Geomembranes and geosynthetic clay liners (GCL) provide relieable contaminant for soil varas, leachate, and groundwater intrusion. Modern composite liners - a geomembrane underlain by a GCL - offer congreer performance equilent to seliat feet of compacted clay while using far less material.

Quantifying Sustainability: A Case Example

Consider a five- kilometer urban roadway on soft clay. Conventional designal calls for 24 inches of aggregate basee over a 12- inch sand blanket requirering embankment widnening.
