Ecological Stone Filter Slab

These ecological stone filter slab is made from refined sand as the raw material, and the entire slab is formed by an 800-ton static press machine. The ecological stone permeable slab not only features the same permeability performance as existing compound sand-based filter bricks but also has higher resistance to pollution, compression, flexure, and a longer service life than sand-based permeable bricks. It is widely used in municipal sidewalk pavement, residential sidewalk pavement, shopping mall squares, light vehicle parking spaces, etc.
