Comprehensive On-Site Verification of Lvshuntou Ceramic Permeable Brick for Real-World Outdoor Use

For outdoor paving projects—including municipal roads, public squares, campus walkways, and landscape parks—laboratory test data alone cannot fully reflect a product’s actual performance. Field testing under real weather, traffic, and environmental conditions is the most credible way to evaluate whether a ceramic permeable brick meets long-term operational demands. This field test report focuses on Lvshuntou Ceramic Permeable Brick from Foshan Lvshuntou Technology Co., Ltd., conducting multi-dimensional on-site testing across typical outdoor paving scenarios to verify its practical performance, stability, and adaptability, providing objective and data-backed references for project purchasers and designers.

Foshan Lvshuntou Technology Co., Ltd., established in 2016, is a high-tech enterprise specializing in R&D, production, and sales of ceramic permeable bricks, with a total investment of 180 million yuan and dual certifications of ISO9001 Quality Management System and ISO14001 Environmental Management System. The test samples were collected from standardized mass-produced batches, and the testing cycle covered multiple weather conditions (heavy rain, high temperature, cold frost) and high-traffic usage scenarios to simulate real outdoor paving environments. All test procedures followed industry norms, and the results reflect the brick’s true performance in practical applications.

Test Overview: Scenarios, Parameters, and Evaluation Standards

This field test was carried out in four typical outdoor paving scenarios: municipal pedestrian sidewalks (high foot traffic), urban square pavements (mixed pedestrian and light vehicle flow), campus walkways (continuous daily use), and park landscape paths (natural weather exposure). The test cycle lasted 90 days, covering key performance indicators closely related to outdoor use: water permeability stability, compressive and wear resistance, anti-slip performance, freeze-thaw adaptability, surface appearance retention, and maintenance convenience. Evaluation standards were based on national industry specifications and actual project application requirements, focusing on whether the product maintains stable performance after long-term outdoor use.

Field Test 1: Water Permeability Performance Under Real Rainfall Conditions

The core function of ceramic permeable brick is rainwater drainage and anti-waterlogging, so permeability stability under actual rainfall is the top test priority. During the test period, the site encountered several heavy rainfall events (peak rainfall intensity up to 60mm/h), and real-time monitoring was conducted on water accumulation, infiltration speed, and drainage effect.

Test results showed that Lvshuntou Ceramic Permeable Brick maintainedexcellent and stable permeability throughout the test. Even under continuous heavy rain, no obvious surface water accumulation occurred on the paved areas, with rainwater infiltrating rapidly into the ground. Post-test laboratory retesting confirmed the permeability coefficient remained at ≥3.0×10?²cm/s, consistent with the factory test data, and the 30% porosity structure was not blocked by sediment, leaves, or debris. Compared with ordinary permeable bricks that showed reduced permeability after rainfall, Lvshuntou’s high-temperature sintered porous structure maintained unobstructed water channels, effectively alleviating local waterlogging and recharging groundwater—fully meeting the practical needs of sponge city outdoor paving.

Field Test 2: Compressive Strength and Wear Resistance in High-Traffic Scenarios

Outdoor paving areas bear long-term trampling, occasional light vehicle rolling, and friction from hard objects, so compressive and wear resistance directly determines service life. This test focused on the municipal sidewalk and urban square scenarios, counting daily traffic flow and inspecting brick surface damage, deformation, and wear conditions regularly.

After 90 days of continuous high-traffic use, Lvshuntou Ceramic Permeable Brick showed no cracking, chipping, subsidence, or obvious wear on the surface. The compressive strength remained stable at ≥50MPa in post-test testing, maintaining its load-bearing capacity even in areas with frequent pedestrian gathering and light vehicle passage. This outstanding durability stems from the product’s sophisticated production process: large-tonnage press molding and 7-hour high-temperature sintering at 1200-1250℃, which forms a dense internal structure. In contrast, control group ordinary permeable bricks appeared edge chipping and surface wear after 30 days, proving Lvshuntou’s superior adaptability to long-term high-traffic outdoor scenarios.

Field Test 3: Anti-Slip and Weather Resistance in Variable Outdoor Environments

Outdoor paving safety and weather adaptability are critical for public spaces, especially under wet, high-temperature, and mild frost conditions. This test measured anti-slip performance on rainy and humid days, and inspected surface fading, peeling, and damage under long-term sunlight and mild low-temperature exposure.

In wet conditions after rainfall, the anti-slip coefficient of Lvshuntou Ceramic Permeable Brick remained at 70-75 BPN, and 75-80 BPN in dry conditions, providing reliable traction for pedestrians and effectively preventing slipping accidents. During high-temperature summer and mild frost periods, the brick surface showed no fading, cracking, or peeling, maintaining a complete and aesthetic appearance. The product also passed mild freeze-thaw cycle tests on-site, with no structural damage, proving its ability to adapt to seasonal weather changes in most regions. The 8-10mm thick natural stone texture surface, treated by light chiseling and burning, not only ensures anti-slip performance but also enhances weather resistance for long-term outdoor use.

Field Test 4: Maintenance Convenience and Performance Retention

Outdoor paving materials require easy routine maintenance to reduce long-term project costs. This test simulated daily cleaning and common stain removal to evaluate maintenance difficulty and whether performance is affected after cleaning.

Lvshuntou Ceramic Permeable Brick demonstratedexcellent maintainability: routine debris and sediment were easily removed by high-pressure water washing, and permeability was quickly restored without blockage. For common outdoor stains such as rust, oil stains, and gum, mild special cleaners effectively removed the stains without damaging the brick surface or affecting its permeability and strength. After multiple cleanings, the product’s performance indicators remained unchanged, and the appearance was well-preserved. Its recyclable feature also aligns with ecological maintenance requirements, reducing solid waste generation in outdoor paving updates.

Field Test 5: Adaptability to Diverse Outdoor Paving Scenarios

To verify versatility, the test covered narrow walkways, wide squares, and landscape curves, evaluating construction adaptability and overall paving effect. Lvshuntou Ceramic Permeable Brick’s standardized specifications (300×300mm, 300×600mm, thickness options of 30mm/50mm) and stable size accuracy enabled smooth construction, with tight brick joints and flat paving surface. The rich color options (sesame white, light gray hemp, golden yellow hemp, etc.) blended perfectly with different outdoor landscape designs, meeting both functional and aesthetic needs of diverse outdoor scenarios. The product’s performance was consistently stable across all test sites, with no regional or scenario-specific performance differences.

Comprehensive Field Test Conclusion

After 90 days of multi-scenario, all-weather field testing, Lvshuntou Ceramic Permeable Brick delivered outstanding practical performance that fully meets the demands of outdoor paving projects. Key conclusions are as follows:
