Dear friends, what are the new construction material used for lining canals these days? We have textured soil and I see that the canal lining is constructed of concrete but still there is noticeable seepage happening.

Can we fix these leakages? I work with irrigation department and I am interested to know some new techniques involved in canal lining construction..

Hi Amanthii, did you investigate some HDPE (plastic) lining products? One example is http://www.smartditch.com/index.html
There are a few other products on the market as well. In my experience, the issue with open irrigation channels is seepage (where unlined) and also evaporation (especially for long channels). Also, regulating / offtake structures cam cause some issues. Please feel free to contact me if you need any further advise. Regards, Iouri
