Selection of pavement bricks for pavement: Pavement bricks for pavement must be filled with pervious bricks (or pervious bricks) that are strong and permeable for pavement. In order to meet the requirements of pedestrian distance use and permeability requirements, in order to be able to meet the cost of the descending project, permeable bricks should be selected in the range of 300 * 300mm. Products that are too small will constitute a beautiful level of overall paving. The thickness should be 50-60mm, and the water permeability be 5-10mm / s, so that it can ensure that the sidewalk can reach the effect of immediate and dry under the conditions of moderate to light rain.
Pavement permeable brick selection guidelines: The purchase of permeable bricks for public roads has stricter requirements on the quality of the bricks themselves.
When purchasing permeable bricks, you can see from the front whether the brick surface is flat and whether pinholes of uneven thickness appear. Together, you can tap the permeable bricks to hear whether the movement is loud and clear. The more brittle the movement, the more dense the texture density High and better hardness.
If necessary, stop the testing of the strength and permeability of professional building materials for permeable bricks to ensure the quality of the project and extend the overall service life of the route.
