What is a benefit of using geomembranes in construction?

Using geomembranes in construction primarily provides a significant benefit in terms of reduced risk of contamination. Geomembranes are synthetic membranes that are impermeable and are used as barriers to prevent the migration of fluids. They play a crucial role in various applications, such as lining landfills, ponds, and containment areas, where they help contain hazardous materials and prevent these contaminants from leaching into the surrounding soil and groundwater.

By effectively sealing off areas, geomembranes ensure that chemicals and other pollutants do not escape, thereby safeguarding the environment and public health. Their use not only helps to protect natural resources but also complies with environmental regulations, reducing liability for construction projects.

In contrast, the other choices highlight undesirable outcomes or implications. Increased noise pollution, higher installation costs, and increased water waste do not align with the primary advantages associated with geomembranes, which are designed to create a safer and more controlled environment in construction settings.
