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

We cannot afford to overlook the issue of geomembrane aging. Aging is an inherent characteristic of polymer materials, and while it cannot be eliminated, appropriate methods can be adopted to delay the aging process of geomembranes. Based on our long-term practice, we have found that methods to postpone geomembrane aging can be approached from two

Geomembranes can be classified into column-point geomembranes and rough-surface geomembranes, which are further divided into four categories: single-rough-surface geomembrane, double-rough-surface geomembrane, single-column-point geomembrane, and double-column-point geomembrane. Geomembranes can also be categorized based on thickness: those with a thickness below 0.8mm are referred to as impermeable membranes, while those with a thickness of 0.8mm or above
