Geosynthetics in roads and pavements

Typical Solutions 

Most water reservoirs, because of their 

magnitude, are lined with low permeability soil 

and left uncovered.  This often results in high 

water treatment costs and potentially serious  

contamination. 

 

Clay or concrete linings have commonly been 

used for water and wastewater conveyance.  

 

The Geosynthetic Solution 

Geomembranes serve as effective protection 

against evaporation and contamination and can 

prevent seepage losses when used as liners and 

floating covers. Though generally used in more 

“highly engineered” installations, their low cost, 

wide spread availability, and relative ease of 

installation make geomembranes and GCLs 

more and more popular for lining architectural 

ponds, recreational ponds, and fire fighting 

ponds

 

as well as for facing dams.   

 

Geomembrane and GCL barrier systems provide 

flexibility and ease of installation which is 

especially beneficial when lining and relining is 

done over existing rigid linings of clay, asphalt, 

or concrete.
