In addition, the leaching of nutrients into bodies of water can lead to water pollution problems such as eutrophication, by causing excessive growth of vegetation. Primary and secondary lining systems will keep excess amounts of chemicals from leaching into the water supply. Flexible liners have been used as a primary and secondary containment for many years in various types of industry, and in the past several years flexible liners have been serving as a superior choice for containment in the fertilizer industry.
Concrete is much more expensive than flexible liners.
Due to variable weather conditions, the expansion and contraction of the concrete can cause it to crack. Adverse weather conditions will not affect flexible liners. Movement of the ground can cause concrete to crack and break. Flexible liners will move with the ground. Leak monitors can be installed with a liner enabling leaks to be repaired before any major damage is done.
