When we are carrying out the stitching operation of geomembrane, we should pay attention to the relevant requirements, so that its performance can be well utilized during the application process. So what are the higher requirements for the stitching process of geomembranes? If you are still not very clear, let is take a look together with HDPE geomembrane manufacturers.

In the practical application of geomembranes in fields such as construction and water conservancy engineering, due to the limitations of their length and width, geomembranes usually require splicing and sewing to better meet the needs of application. In order to fully utilize the anti-seepage, reinforcement and other product application characteristics of geomembranes, as well as to achieve the beauty of stitching, high requirements have been put forward for the stitching techniques of geomembranes.

The stitching of geomembranes must be continuous, and the stitches should be fine and precise. Just like how we mend clothes, if the stitches are too large during continuous use, they will become difficult to pull and tear, making it very easy to tear. After splicing and sewing the geomembrane, simple edge locking is required for reinforcement application.

Both the assembly of geomembranes and the use of locking lines require the selection of materials with strong tensile strength, chemical corrosion resistance, and UV radiation resistance. And after the application of geomembrane stitching, it is necessary to conduct repeated inspections on the geomembrane, and timely repair the seams at the places where the needle is missing or the thread is detached.

The sewing of geomembrane is a profound knowledge, and it is generally not possible for inexperienced workers to operate it. We use different sewing methods in different environments, and it is necessary for you to choose the appropriate sewing method based on your own construction characteristics. Hot air welding is a method of connecting geomembranes, which involves heating two pieces of cloth immediately at high temperatures with a hot air gun, melting them, and immediately using a certain external force to firmly bond them together. In humid (rainy or snowy) climates, soil cannot be bonded through thermal bonds. The fabric should be sewn using a special sewing machine, and the stitching thread and anti UV thread should be sewn together.

These are the relevant requirements that need to be paid attention to when carrying out geomembrane stitching operations, and we hope that we can abide by its relevant standards and requirements during the stitching process.
