- Advantages: Hard stone, wear and acid-base resistant, long service life, and aesthetically pleasing appearance, enhancing the overall quality of the road.
- Concrete curbstone
- New Composite Model: Double-layered design with the upper layer made of C30 concrete for strength and the lower layer with porous concrete for water permeability. The back features through-hole conduits for drainage guidance.
- Advantages: Cost comparable to traditional concrete curb stones, but with improved permeability, suitable for sponge city projects and other drainage scenarios.
