Geosynthetics to reduce seepage losses and improve the structural integrity of canals

With technological advancement, many man made materials are replacing the age-old materials and methods. Geosynthetics is one such class that is now an irreplaceable solution in various engineering fields. As with various other sectors in the agricultural area also geosynthetics are not just an economically viable but performance-oriented and durable option. Alone or in conjunction with different layers, geosynthetics increase the efficiency of canal irrigation.

The various geosynthetics for canal lining include geotextiles, geomembranes, geogrids, and geonets. They perform the functions of filtration, drainage, and impermeability, depending on the application.

While geomembranes are impermeable sheets, geonets are made of HDPE and find use as drainage nets. Geotextiles, on the other hand, are an added protective layer to the geomembranes, making them puncture resistant. Geogrids serve to support the lining system where there is poor subgrade.

Of all the geosynthetics, the geomembranes for canal lining are the star performers in use since the 1950s. HDPE geomembranes are by far the chosen geosynthetic for canal linings. They perform exceptionally well and offer chemical, hydrocarbon, and abrasion resistance that make them so popular.

LLDPE geomembranes with greater flexibility than HDPE are ideal for projects with a differential settlement. EPDM, highly flexible and stable, conforms to the canal’s shape, easily making it suitable for old installations as well. PVC geomembranes, also flexible, are ideal for quick installation.

The high-density polyethylene geomembranes at Ocean Geosynthetics offer excellent mechanical strength, chemical stability, high impervious coefficient, long service life with aging resistance and puncture resistance, all at a low cost, and being environmentally friendly.
