When building a fish pond, the choice between cement and impermeable membrane is a common problem. To solve this problem, we need to consider multiple aspects.
First, let's learn about impermeable membranes. Impermeable membrane is a kind of plastic film with good waterproof performance and corrosion resistance. Compared with cement, impermeable membrane has better flexibility and adaptability, and can well adapt to the uneven settlement of the foundation and effectively prevent leakage. In addition, the impermeable membrane has high tensile properties and can withstand the stresses caused by the deformation of the foundation. Therefore, in places where the geological conditions are more complex and the foundation is prone to uneven settlement, the use of impermeable membrane can better avoid the leakage problem caused by foundation deformation.
However, impermeable membranes also have some drawbacks. First of all, the durability of the impermeable membrane is not as good as cement, and it is affected by natural factors such as ultraviolet radiation, wind and rain for a long time, and the impermeable membrane is prone to aging, cracking and other problems, resulting in a decline in waterproof performance. Secondly, the installation quality of the impermeable membrane is high, and if the installation is not standardized or the joints are not properly handled, it is easy to leak. In addition, the impermeable membrane is also relatively high.
In contrast, cement has higher durability and stability. After hardening, cement has strong compressive and impermeable properties and is not easily eroded by natural factors. At the same time, the cement is relatively low and has better economy. However, the flexibility of cement is poor, and it is easy to be limited by the deformation of the foundation, and if the foundation settles unevenly, it may cause cracks in the cement pool body and affect its waterproof performance.
To sum up, the choice of using cement or impermeable membrane needs to be comprehensively considered according to the actual situation. If the geological conditions are complex, the foundation is prone to uneven settlement, or the requirements for waterproofing are high, the use of impermeable membranes may be more appropriate. In the case of higher economic requirements and a more stable foundation, the use of cement may be more appropriate.
Of course, no matter which material you choose to use, the quality of the construction is very important. During the construction process, the construction should be carried out in strict accordance with the relevant specifications to ensure the quality of construction. At the same time, in the process of use, it is also necessary to carry out regular inspection and maintenance, find and deal with possible problems in time, and ensure the long-term stable operation of the fish pond.
In addition, for some special cases, it may be necessary to consider a combination of two materials. For example, when building a large fish pond, you can consider using cement at the bottom and wall of the pond, and using impermeable membrane on the part of the pond wall in contact with the soil, which can combine the advantages of the two materials, not only ensure the waterproof performance of the fish pond, but also improve its durability and stability.
In short, when choosing fish pond building materials, it is necessary to consider comprehensively according to the actual situation. Whether it is cement or impermeable membrane, it is necessary to carry out construction in strict accordance with relevant specifications to ensure the quality of construction. Only in this way can a fish pond be built that is both beautiful and functional.
