Description: Approximately 7.5 percent of the irrigable land in Southern Alberta, or 50,000 acres, has been salinized be cause of seepage from canals and ditches. This seepage can be effectively controlled by lining the canals and ditches with relatively impermeable materials. Polyethylene and compacted clay have been the most popular lining materials in Southern Alberta. Except for a few isolated cases, concrete has not been used, probably because of its high initial cost and a lack of know ledge of its performance under the widely fluctuating temperatures of the chinook climate in the area. In 1914 a half-mile of concrete lining was manually placed in a canal near Strathmore, Alberta, by the Canadian Pacific Railway (5). In 1966 the lining appeared to be still in good condition but no quantitative information on its effectiveness in seepage control is available. In 1950 a 964-foot section of canal near Swift Current, Saskatchewan, was lined with shotcrete (pneumatically applied mortar) as part of a study undertaken by the Prairie Farm Rehabilitation Administration (PFRA) ott canal and dugout linings. In 1953, both precast concrete slabs and
