In the field of building waterproofing engineering, problems such as roof leakage, basement water accumulation, and low drainage efficiency have long troubled industry practitioners. Traditional drainage systems often have pain points such as slow drainage speed, easy blockage, and damage to the waterproof layer under pressure, resulting in a shortened lifespan of the building structure and increased maintenance costs. Jiamei New Materials Co., Ltd., as a professional manufacturer with more than a decade of experience in the drainage system, is located in Tai'an High - tech Development Park, covering an area of 32,000 square meters, and focuses on the research and development of sponge city system materials. Our original "blockchain" intelligent drainage collection system, through the innovative application of high - density polyethylene (HDPE) waterproof and drainage protection boards, realizes organized siphon drainage with zero slope on the planted roof, effectively solving the above - mentioned industry pain points.
Core working mechanism:
- Driven by siphon effect: Use the liquid level difference to generate negative pressure to achieve rapid and active drainage
- Three - dimensional drainage structure: The conical columns support to form a drainage cavity, improving the drainage efficiency by 20%
- Composite protective layer: HDPE substrate + non - woven fabric filter layer for double protection of the waterproof layer
Product technical parameters:
| Parameter item | Technical index | Test standard |
|---|---|---|
| Material composition | High - density polyethylene (HDPE) ≥95% | GB/T 1040.2 |
| Thickness specification | 1.2mm/1.5mm/2.0mm (customizable) | GB/T 6672 |
| Compressive strength | ≥250kPa (25 tons/m²) | GB/T 1041 |
| Drainage flux | ≥0.8 cm³/s (at a slope of 5°) | ASTM E2780 |
| Temperature resistance range | -40℃~80℃ | GB/T 5470 |
Five core advantages:
- Improved durability: The HDPE material is resistant to acid and alkali corrosion, with a service life of ≥30 years.
- Optimized construction efficiency: The standard board size is 2m×15m, and the daily laying area can reach 2000m².
- System compatibility: It perfectly matches system components such as PED polymer protective drainage profiled sheets and HXC siphon drainage channels.
- Ecological benefits: The rainwater collection rate is increased by 40%, contributing to the construction of a sponge city.
- Economy: The maintenance frequency of the waterproof layer is reduced, and the comprehensive cost is reduced by 35%.
As an enterprise certified by the ISO9001 quality management system, we hold 4 invention patents and 22 utility model patents to support product innovation. The company has the second - level construction qualification for waterproofing, anti - corrosion, and thermal insulation, as well as a safety production license, with an annual production capacity of 50 million square meters, ensuring a stable supply of goods. It is recommended that project parties focus on the root - penetration resistance of materials and the drainage response speed of the system when selecting a drainage system. We can provide free technical solution comparison services. For large - scale underground projects, it is recommended to use our sediment observation well system for visual operation and maintenance.
Frequently Asked Questions:
-
Q: What is the essential difference between siphon drainage and traditional gravity drainage?
A: Siphon drainage uses the liquid level difference to form negative pressure, realizing active and rapid drainage. The efficiency is about 40% higher than that of gravity drainage. It is especially suitable for zero - slope roofs and can effectively solve the problem of water accumulation. -
Q: Will the HDPE material age during long - term use?
A: We use virgin high - density polyethylene raw materials, add anti - aging agents and UV stabilizers, and pass the 2000 - hour aging test according to the GB/T 16422.3 standard, ensuring a service life of more than 30 years in outdoor environments. -
Q: How to ensure the coordinated work of the drainage board and the waterproof layer?
A: The convex point design of the drainage board forms a 5mm air layer to disperse the upper load. At the same time, a special adhesive is used to form a complete protection system, reducing the risk of damage to the waterproof layer due to pressure. -
Q: How to ensure the drainage effect for roofs with special - shaped structures?
A: We provide 3D scanning customization services. Optimize the drainage path through BIM modeling and cooperate with HXC siphon drainage channels to achieve organized drainage for complex structures, ensuring no dead ends in drainage. -
Q: Does the system require special maintenance?
A: It is recommended to check the system status through the ventilation observation tube every 2 years. The supporting geotextile filter layer can effectively prevent blockages, and no special maintenance is required under normal use conditions. -
Q: Can you provide a complete system solution?
A: We have the construction qualification for waterproofing, anti-corrosion, and thermal insulation. We can provide a full - set system design and construction guidance services from PED protective drainage special - shaped sheets, siphon drainage channels to water storage modules.
