How to Lay Polyethylene Geomembrane
Polyethylene geomembrane is widely used in large-scale infrastructure construction such as highways, railways, and water conservancy bridges and tunnels because of its good anti-seepage effect. It depends on the unique properties of polyethylene high quality environmental geomembrane itself and is loved by engineering design and construction workers. The tensile strength and elongation of the film and the effect of water separation are relatively good, so how should we lay it in the actual construction?
In addition to the good water-proof effect, the polyethylene environmental geomembrane manufacturers can also play a role in filtering and isolating the anti-seepage effect. As far as possible, the construction date should be at a temperature above 5 degrees Celsius, and the wind should be as low as possible. If it encounters rain and snow, the construction should be stopped. Cover and protect the parts that have been completed.
If necessary during the laying process, it can be cut and spliced according to the corresponding size. In order to effectively connect the cut parts, a special glue or welding machine is generally used for the lap joint to lap, so as to ensure 100% waterproof. In addition, it is necessary to lay and press while laying so as to prevent it from being blown up by strong wind.
It should be noted that if there are holes or damages in the polyethylene LDPE geomembrane for sale during the laying process, don’t discard it casually, just cut the corresponding area from the side of the product. Generally speaking, in order to ensure the effectiveness of the cutting, it is necessary to repair the scar. The area should be larger than the damaged area.
For the composite geomembrane, all indicators need to reach a certain level during construction to ensure the quality of the construction. So when you are performing composite high quality textured geomembrane construction, do you know what is hydrostatic pressure resistance? So why is hydrostatic pressure very important for composite geomembrane?
The hydrostatic pressure resistance of the composite geomembrane is related to the anti-seepage effect of the anti-seepage high quality LDPE geomembrane. It is a very important index value related to the characteristics of the composite geomembrane waterproof layer.
Hydrostatic pressure resistance refers to the resistance of the membrane material in the composite geomembrane to pressure under static conditions. Generally, the thicker the composite geomembrane is, the stronger the hydrostatic pressure resistance is. The higher the quality of the composite LDPE geomembrane manufacturers is, and the higher the waterproof layer is.
Generally speaking, the hydrostatic pressure resistance is an important indicator to measure whether the composite geomembrane is qualified. To make the hydrostatic pressure resistance of the composite geomembrane stable and qualified is to hone an enterprise’s production line equipment and production process flow. Is it more than the most representative of the national regulations? One of the standards.
Through the above introduction of the hydrostatic pressure resistance of the composite textured geomembrane for sale, I believe everyone has a certain understanding of it. The quality of a product is not just about the performance of one side. Only after a comprehensive investigation of the products can we choose the right product.
