1. Protection of Roots Tree roots are essential for the stability and health of the plant. They extend outwards and can be easily damaged by pedestrians, vehicles, or maintenance equipment.

In addition to safety and durability, the design of a 500mm round drain cover can significantly impact the overall drainage system’s efficiency. A well-fitted drain cover allows for optimal water flow into the drainage system, even during heavy rainfall. The perforations in the cover design enable water to seep through while preventing larger debris from entering the system. This efficiency helps mitigate flooding in urban areas, ensuring that stormwater is effectively channeled away from roads, sidewalks, and buildings.
