What material is typically recommended for high-rise building drainage systems?

In high-rise building drainage systems, cast iron pipe is typically recommended due to several advantageous properties that align with the demands of such constructions. Cast iron is known for its durability and strength, which are essential in high-rise applications where the weight of the waste and the potential pressure from the vertical columns can be significant.

Additionally, cast iron provides excellent sound-dampening qualities, which helps to reduce noise from wastewater flow, an important consideration in densely populated apartments or offices. Its resistance to corrosion and ability to withstand high temperatures also make it suitable for various waste materials commonly found in drainage systems.

Overall, the combination of longevity, sound insulation, and structural capability makes cast iron an ideal choice for high-rise drainage systems.
