In the field of building waterproofing engineering, problems such as leakage of underground structures and over - limit of roof load caused by low drainage efficiency have long troubled the industry. Traditional drainage systems have defects such as drainage blind spots and insufficient material durability. Especially, the zero - slope drainage requirement for planted roofs has become a technical difficulty. Jiamei New Materials Co., Ltd. has been deeply involved in the drainage system field for more than a decade. Relying on a 32,000㎡ production base in Tai'an High - tech Development Zone, it focuses on researching and developing sponge city system materials and innovatively launches a blockchain - enabled intelligent drainage and collection system.
This product breaks through industry bottlenecks through three patented technologies: ① Polymer substrate modification technology (Patent No. ZL201810xxxxxx) increases the compressive strength of HDPE materials by 40%; ② Three - dimensional drainage structure design (Patent No. ZL201920xxxxxx) enables active siphoning at zero slope; ③ Modular quick - installation system shortens the construction period by 50%. Verified by the National Building Materials Testing Center, this system still maintains a drainage efficiency of over 95% under a 1.5 - meter soil - covering pressure, completely solving the leakage risk caused by roof water accumulation.
- Siphon power generation: The conical drainage trough generates negative pressure attraction to achieve unpowered drainage
- Three - dimensional drainage path: Four - level diversion from the upper water - guiding layer → middle water - storage layer → siphon drainage trough → water collection well
- Blockchain monitoring: Embedded sensors monitor real - time data on flow, pH value, and temperature
| Project | Standard value | Test method |
|---|---|---|
| Substrate density | 0.94 - 0.96g/cm³ | GB/T1033.1 |
| Compressive strength | ≥350kPa | GB/T1041 |
| Water conductivity | ≥0.003cm/s | ASTME1745 |
- All-weather construction: Maintain flexibility in an environment from -30°C to 80°C
- Composite protection structure: Triple composite of HDPE substrate + non-woven filter layer + anti-puncture membrane
- Intelligent operation and maintenance: Achieve early warning of drainage volume through the Internet of Things platform (requires the use of a sediment observation well)
As an enterprise with the second-level construction qualification for waterproofing, anti-corrosion, and thermal insulation, Jiamei New Materials Co., Ltd. has provided drainage solutions for large-scale projects such as Wanda Plaza and China Resources Land. Relying on the production capacity guarantee of 50 million square meters per year from 25 production lines, and combined with the technical barriers formed by 37 registered trademarks and 6 software copyrights, we recommend: Adopt the combined solution of siphon drainage trough + water storage module in the basement project of commercial complexes, which can reduce the maintenance cost by about 30%. If you need to obtain the drainage calculation report for your project, please contact our technical team for load simulation analysis.

Q: Is the system applicable to sloping roofs?
A: The core advantage of this product lies in zero-slope drainage, which achieves siphoning through the patented drainage trough (patent number ZL202020xxxxxx) to form a gravity difference. For sloping roofs, a segmented diversion design is recommended. When the slope is >5%, a water retaining weir is required. -
Q: How is the root puncture resistance of HDPE materials?
A: Tested by a CMA-certified laboratory (report number HJ2023-086), the 2.0mm thick substrate showed no penetration in the national standard Class II root puncture test. It is recommended to add a root barrier layer when the planting depth is >80cm. -
Q: How to maintain the drainage system when it is blocked?
A: The three-layer filtration structure design can intercept particles >0.2mm. Combined with the sediment observation well (patent number ZL201920xxxxxx), visual management can be achieved. Data statistics show that the self-cleaning rate of the system is >92%, and maintenance by high-pressure air flushing is only required every five years.
