In the field of construction engineering, problems such as basement leakage, water accumulation on planted roofs, and low drainage efficiency have long troubled construction parties and owners. Traditional drainage materials are prone to aging, have poor compression resistance, and have chaotic drainage paths, resulting in an increase of over 50% in the risk of structural leakage. Jiamei New Materials Co., Ltd., as a professional manufacturer with more than a decade of experience in the drainage system, relying on 4 invention patents and 22 utility model patent technologies, has innovatively developed HDPE building water storage and drainage boards. We are located in Taian High - tech Development Park, with 25 automated production lines, producing 50 million square meters of drainage materials annually. We provide "blockchain" intelligent drainage system solutions for leading real - estate enterprises such as Vanke and Greenland, and solve the pain points of building drainage from the root.
Product working mechanism: It adopts a three - dimensional arch support structure design to form a three - dimensional space of "drainage - water storage - ventilation". After the water is filtered through the upper geotextile, efficient management is achieved through the following paths:
- 80% of surface water is quickly led into the water collection system through the drainage trough.
- 15% of the water is temporarily stored in the arched water storage bin to relieve the impact of heavy rain.
- 5% of water vapor maintains the soil moisture balance through the ventilation holes.
| Technical parameters | Standard value | Customization range |
| Material thickness | 1.2mm | 0.8 - 2.5mm |
| Plane compressive strength | ≥20kN/m² | 15 - 50kN/m² |
| Drainage flux | 0.8m³/h·m | 0.5 - 1.5m³/h·m |
| Water storage capacity | 32L/m² | 20 - 60L/m² |
| Operating temperature | -40℃~80℃ | -50℃~100℃ |
Six core advantages: ① Made of HDPE virgin material, it has passed the acid - alkali resistance test of GB/T17643 - 2011, and the service life is extended to 25 years; ② The patented self - adhesive geotextile interface (patent number ZL201810842XXX) reduces the risk of joint leakage by 60%; ③ The modular assembly design improves the construction efficiency by 40%; ④ The arched support structure provides a compressive strength of 18 tons/m²; ⑤ The double - sided filtration design has an effective pore size of 0.06mm to block sediment; ⑥ It supports customized services such as special - shaped cutting, thickness adjustment, and LOGO embossing.
As an enterprise with the Class II construction qualification for waterproofing, anti-corrosion, and thermal insulation, we have served 327 large-scale real estate projects. Verified by the National Building Materials Testing Center, when this product is used in conjunction with the siphonic drainage system, the leakage rate of basements can be reduced by 82%. It is recommended that project parties select different water storage capacity configurations based on the geological survey report:
- In rainy areas, water storage models with a capacity of over 40L/m² are recommended.
- For commercial plazas, specifications with a compressive strength of ≥35kN/m² should be selected.
- For roof gardens, it is recommended to use them in combination with ventilation observation pipes.
FAQ：
Q: Why choose HDPE instead of PP material?
A: The density of HDPE (0.94 - 0.96g/cm³) is higher than that of PP (0.89 - 0.91g/cm³). Under the same thickness, its puncture resistance is improved by 35%, and the environmental stress cracking resistance time is > 1500 hours (testing standard: GB/T1842), making it more adaptable to the environment of foundation deformation.
Q: How does the self-adhesive geotextile ensure sealing?
A: Our patented sticky bar technology (patent number: ZL201821358XXX) is used. A 3cm-wide sealing strip is formed through the SBS modified asphalt coating, and the peeling strength reaches 0.8kN/m (testing standard: GB/T2790), far higher than the 0.3kN/m standard of ordinary adhesives.
Q: How long is the customized production cycle?
A: For standard specifications, the products will be shipped within 72 hours. Orders for special-shaped cutting or special thicknesses will take 5 - 7 days. We have 3 flexible production lines dedicated to customized orders, and the minimum order quantity is 500m².
Q: How to verify the drainage effect?
A: It is recommended to install a sediment observation well (patent number: ZL202020445XXX) to monitor the drainage efficiency through the water level change in the well. We provide free hydraulic model calculation services to pre-simulate the drainage performance under different rainfall intensities.
Q: Will it crack under extreme low temperatures?
A: The HDPE material has passed the -50℃ cold bending test (testing standard: GB/T5470) and still maintains a breaking elongation of > 8% at -40℃. For projects in the north, it is recommended to choose thickened models over 2.0mm.
Q: What are the advantages compared with the traditional pebble drainage layer?
A: The drainage capacity of 1m² of drainage board is equivalent to that of a 0.3m-thick pebble layer, but its self-weight is only 1.8kg (the pebble layer is about 120kg), reducing the structural load by 85% and the comprehensive cost by 42%.
