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 […]

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

Precautions during geomembrane construction: 1. Tool Handling: After use, the blade of the membrane-cutting knife must be immediately retracted into its protective sheath. 2. Temporary Tool Storage: All small temporary tools used on-site should be promptly stored in designated toolboxes after use. 3. Welding Material Disposal: Welding residues removed from the extrusion welder nozzle must
