Generally, it is determined according to construction requirements. The primary function of a geomembrane is seepage prevention. Geomembranes are not only used in hydraulic engineering but also in the storage projects of solutions with complex chemical compositions or industrial waste. When applied in different seepage prevention projects, the selected thickness of geomembranes varies. The thickness […]

Many farmers and fishermen are accustomed to calling it a waterproof membrane. Laying geomembranes for fish pond waterproofing can help control water quality, facilitate easy cleaning, prevent the residual accumulation of harmful and toxic bacteria, and also protect embankments from being undermined by waves. Generally, fish ponds use geomembranes in three specifications: 0.4mm, 0.5mm, and

In engineering projects, the efficiency of the drainage system is crucial for the safety and durability of the project. The three-dimensional composite drainage net is a commonly used material in various major engineering projects. So, what are its advantages? I. Overview of Three-Dimensional Composite Drainage Net The three-dimensional composite drainage net is made by bonding

The laying and welding of geomembrane at the intersection of slopes are special cases. Diaphragms within irregular areas, such as corners, should be cut into an “inverted trapezoid” shape, with a smaller upper width and a smaller lower width (Note: There seems to be an error in the original text where it says “upper width

Composite geomembrane is an efficient anti-seepage material widely applied in various engineering projects to improve waterproofing performance. Here are some specific methods and measures: 1. Optimization of Laying Techniques: > Flat Laying: The contact surface between the composite geomembrane and the supporting material should be as flat as possible to prevent the membrane from being

In landfills, the treatment and discharge of leachate are of great importance. Composite drainage network is a commonly used drainage material in landfills. So, can it come into direct contact with landfill leachate? I. Basic Characteristics of Composite Drainage Network Composite drainage network is made of high-density polyethylene (HDPE) and other polymer materials, featuring a

Before purchasing geotextiles, several factors need to be considered. Here are our suggestions for buying geotextiles: 1. Density of the geotextile: A higher grammage (weight per unit area) indicates greater resistance. It is recommended to choose a geotextile cover with a minimum grammage of 100 grams per square meter. 2. Woven or non-woven geotextile fabric:

Retaining walls are a commonly used structure in civil engineering, primarily designed to resist the lateral pressure of soil and prevent phenomena such as soil landslides and collapses. With the development of engineering technology, geogrids, as a new type of reinforcing material, have been widely applied in the construction of retaining walls. This article will
