Lining a canal with concrete comes with pros and cons. Concrete liners are highly resistant to water seepage, erosion, and physical damage, making them ideal for canals with high flow rates or heavy traffic. Concrete also provides a smooth surface that improves water flow efficiency and can handle extreme environmental conditions. However, there are some drawbacks.
Concrete is prone to cracking over time due to temperature fluctuations, soil movement, or pressure from water flow. Cracks can lead to leaks and require costly repairs. The installation process is labor-intensive and can be expensive, particularly when reinforcing the concrete or preparing the canal bed. Concrete liners also lack flexibility, making them less suitable for areas with unstable or shifting soil.
