Ceramic permeable bricks are generally permeable through the pores on the surface of the brick body, or through the gaps between bricks. If water can pass through the top surface of the block, then this permeable brick uses the gaps between bricks for permeability. The surface of this brick is relatively flat and beautiful, but its permeability is relatively poor.

Can water pass through the top surface of the block, can water pass through the pores of the block, and can water directly penetrate to the bottom surface of the block.

If water cannot pass through the top surface of permeable bricks and is permeable through pores, the surface of inferior permeable bricks on the market is relatively rough and the pores are very large. This type of permeable brick has a relatively low service life and a short permeable time. Why is that said? One of the major characteristics of large pore permeable bricks is that they are easily blocked by dust. Once blocked, they lose the function and value of permeable bricks, but the cost of such large pore permeable bricks is relatively low.

If water can directly penetrate the bottom surface of the block and its surface is very dense, this ceramic permeable brick has a long permeability time and a long service life, and is the recommended permeable brick product.
