Which materials are acceptable for constructing a level spreader?

• A. Concrete, wood, or prefabricated metal with well-anchored footer
• B. Plastic lining
• C. Asphalt
• D. Stone and brick

Answer: (A)

Level spreaders must provide a stable, durable surface that won’t shift or erode under runoff and can be securely anchored to resist movement. Concrete, wood, or prefabricated metal sections with a well-anchored footer meet those requirements, giving a solid, stable platform that distributes flow evenly and stays in place over time. Plastic lining isn’t suitable because it can wear, puncture, or fail under flow and isn’t a rigid support. Asphalt can crack or deform with temperature changes and over time, compromising distribution. Stone and brick can settle or create irregular surfaces and gaps that disrupt uniform flow. So the materials that best ensure long-term stability and proper function are concrete, wood, or prefabricated metal with a well-anchored footer.
