The Evolution of Drainage Systems: From Cast Concrete to Modern Composite Materials
In the world of construction and infrastructure, drainage systems play a crucial role in maintaining structural durability and preventing water pooling that can damage the environment and property. In the past, drainage systems were closely associated with cast concrete, which is heavy and requires a long installation time. Today, however, the industry is shifting toward more advanced solutions: modern composite materials such as Polypropylene (PP), BMC (Bulk Molding Compound), and Polymer Concrete.
