• For procurement requirements that require the use of permeable bricks, it is recommended to prioritize confirming the permeability coefficient and compressive strength parameters of the product. Generally, municipal road scenarios require a permeability of ≥ 1.5 × 10 ⁻ cm/s, while parking lot areas need to pay attention to a strength grade of ≥ C40.
• Permeable bricks are suitable for rainwater gardens, pedestrian walkways, and other scenarios in sponge city construction. When purchasing, corresponding thickness specifications can be selected based on the load-bearing requirements of different areas. For example, 50mm is suitable for light pedestrian walkways, and 80mm or more is suitable for vehicular traffic areas.
• When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support or platform statistical information. Especially suppliers with municipal engineering cases are worth paying attention to.
• In the actual procurement process of permeable bricks, it is recommended to compare the porosity data (generally 20% -30%) and freeze-thaw cycle times (recommended to be ≥ 50 times in northern regions) provided by different suppliers to ensure long-term performance.
