3.Disadvantages of HDPE Membrane
3.1. High requirements for foundation conditions
The anti-seepage effect of HDPE Membrane depends largely on the foundation conditions for its laying. If the foundation is uneven, has sharp objects or cracks, it can directly affect the anti-seepage performance and service life of the geomembrane. Therefore, before laying the HDPE Membrane, the foundation must be strictly inspected and treated to ensure that it meets the laying requirements.
3.2. Susceptible to ultraviolet rays
Although it has good weather resistance, it will still age if exposed to strong ultraviolet rays for a long time, resulting in performance degradation. Therefore, when used outdoors, sunshade and sun protection measures should be taken to protect the geomembrane from ultraviolet rays.
3.3.High cost
It is a high-performance engineering material with a relatively high price. This limits its application in some low-cost engineering projects to a certain extent. However, considering the effects of it in anti-seepage, isolation and other aspects and its long service life, its cost-effectiveness is still highly competitive.
It the advantages of excellent anti-seepage performance, good physical and chemical stability, simple construction, environmental protection and energy saving, etc., and can be used in many fields.
However, it also has disadvantages such as high requirements for basic conditions, susceptibility to ultraviolet rays and high cost. Therefore, when using HDPE Membrane, its advantages and disadvantages should be fully considered, and reasonable selection and application should be made in combination with specific engineering conditions.
4. Is HPDE membrane really effective?
HDPE Membrane, a geotechnical material with excellent anti-seepage and waterproof properties, finds extensive applications. Given its technical characteristics during actual processing, it demands strict process requirements across all aspects. For instance, in environmental protection and sanitation projects, we use HDPE Membrane to enhance anti-seepage when constructing garbage dumps or sewage treatment plants. This significantly improves anti-seepage performance, making its process standards and advantages increasingly evident. We also widely apply its materials in the anti-seepage of underground projects and building roof gardens. This continuous expansion of its application scope ensures a more prominent actual anti-seepage effect. Moreover, HDPE Membrane features good aging resistance and strong anti-decomposition ability.
