Drain gasket PE plays an important role in improving the drainage efficiency of buildings or green spaces.
1. Material advantages
Drain gasket PE is usually made of high-quality materials such as high-density polyethylene (HDPE), which have excellent flexibility and tensile strength and can adapt well to various terrains and building structures. At the same time, PE materials also have good weather resistance and aging resistance, ensuring that the gasket maintains stable performance during long-term use.
2. Structural design
Concave-convex hollow structure: drain gasket PE usually adopts a concave-convex hollow structure, which can quickly and effectively drain rainwater and reduce or even eliminate the hydrostatic pressure of the waterproof layer. The concave-convex structure can also increase the contact area between the gasket and the ground and improve drainage efficiency.
Three-dimensional drainage channel: A three-dimensional drainage channel is formed inside the gasket, so that rainwater can be quickly discharged into the lower soil or drainage system through the gasket. This design not only increases the drainage speed, but also helps prevent water accumulation from damaging buildings or green spaces.
3. Functional characteristics
Efficient drainage: drain gasket PE can quickly drain the accumulated water, avoid soil saturation and water penetration, and thus protect the structure and internal facilities of the building.
Rainwater retention and purification: Through the combination with the drainage trough, drain gasket PE can effectively retain rainwater, providing conditions for plant growth and natural soil penetration. At the same time, through plant purification and natural soil and geotextile penetration, the water quality is purified to meet the emission standards.
Reducing the pressure on the waterproof layer: drain gasket PE is light in weight and easy to lay, which can reduce the pressure on the waterproof layer and extend the service life of the waterproof layer.
Secondary waterproof function: The gasket can also effectively prevent damage such as tree puncture, liquid corrosion and insect bites on the planting surface, providing additional waterproof protection.
4. Application scenarios
drain gasket PE is widely used in projects such as roof greening, basement foundations, tunnels, etc., and is also suitable for drainage and water storage projects on roads, railways, golf courses and farmland. In these scenarios, the gasket can effectively improve the drainage efficiency and protect the foundation surface from groundwater erosion.
5. Installation and maintenance
Easy installation: drain gasket PE is easy and quick to lay. Two ordinary workers can lay a large area of ground in one day, which greatly improves the construction efficiency.
Easy maintenance: The gasket is easy to check and maintain during use. Once damage or blockage is found, it can be handled in time to ensure the normal operation of the drainage system.
In summary, drain gasket PE plays an important role in improving the drainage efficiency of buildings or green spaces through its material advantages, structural design, functional characteristics and a wide range of application scenarios.
