Abstract
The most important prerequisite of linings for controlling seepage losses from irrigation canals is their watertightness. In addition to being watertight, a lining must be relatively durable if it is to be economical. Rigid materials provide satisfactory linings for canals with well-drained and stable subgrades. Under other conditions, where expansive soils are encountered and ground water is a problem, a rigid lining such as concrete is not durable. Considering the many factors that govern the utility and durability of linings, the ideal lining would consist of a material with some flexibility, a material resistant to erosion and mechanical damage, and one with a smooth surface. The search for a material of this type led to a consideration of asphalt and rubber-coated materials. Natural rubber, while watertight, deteriorates rapidly. Some of the synthetic rubbers such as butyl, on the contrary, show high resistance to deterioration from weathering and biological activity.
