What is the minimum gradient for concrete drains?
It’s a value connected to your drainage discussions.
True or False: Minimum gradients are not important for road drainage.
Think about the consequences of pooling water.
Given a newly constructed road in an area prone to heavy rainfall, calculate the ideal minimum gradient required to avoid pooling. Consider soil type, rainfall intensity, and local regulations.
