Message-ID: <35CC98B7.13AD@es.com.sv> Date: Sat, 8 Aug 1998 12:28:07 -0600 From: Cesar P Tablas <geomat@es.com.sv> Subject: Channels over Expansive Soils To: CIVIL-L@hermes.csd.unb.ca To concerned subscribers: Could you share your experiences with us if you have been involved in lining irrigation channels over very expansive soils. We are interested in knowing the different solutions implemented, long term results and current practice in your area. We are dealing with the lining of an existing irrigation channel which traverses zones of very expansive clays (average LL=100%, PI=70%, Clay=60%). The first meter above the channel's bottom is very soft and the underlying clay is very stiff. We will appreciate your comments. Cesar P Tablas Civil Engineer El Salvador
