You will read lots of know-how articles here in this category and learn all aspects of the geosynthetic industry.
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 […]
Composite geomembranes, including types such as “two-fabric-one-membrane,” “one-fabric-one-membrane,” and “multi-fabric-multi-membrane,” are non-woven composite geomembranes fabricated using non-woven geotextiles as the base material and polyethylene (PE), polyvinyl chloride (PVC), or other polymers as the membrane material, combined through a composite process. These geomembranes offer features such as isolation, reinforcement, drainage, slope protection, as well as high

Let’s explore the distinctions together: 1. Felt: The greenhouse felt we commonly use is familiar to most. It comes in a wide variety of types, primarily in colors such as floral, black, and gray. In contrast, geotextiles are predominantly white. 2. Density: Geotextiles have a higher density. Within a unit square area, the density of
What are the quality indicators and testing methods for geotextiles? 1. Physical Properties The physical properties of geotextiles primarily include the determination of mass per unit area and thickness. For mass per unit area measurement, ten test specimens, each with an area of 10,000 square centimeters, are cut. The cut specimens are then weighed individually

Geotextile is a special material used in civil engineering, featuring good tensile strength and waterproof performance. To ensure its long-term effectiveness, proper maintenance methods are of crucial importance. Here are some effective maintenance approaches for geotextiles: I. Pre-use Preparations 1. Surface Cleaning: Before use, carefully inspect the surface of the geotextile for dust, gravel, or
Geomembrane UV resistance test and discussion The national standards GB/T17643-2011 and CJ/T234-2006 both stipulate the anti-ultraviolet performance indicators of geomembranes, but the difference from the American standard GM 13 directive is that after 1600 hours of anti-ultraviolet performance, the geomembrane After the test, it is evaluated by whether the retention rate of OIT before and
Analysis of interface shear failure and peak strength of geomembrane and polyester filament geotextile Geosynthetic materials such as geomembranes and geotextiles are widely used in fields such as environmental protection, transportation, water conservancy, agriculture, and construction waterproofing. Since the shear strength between geosynthetic materials interfaces is weak, the slip stability of slopes containing geosynthetic materials
Experimental Welding Requirements for HDPE Geomembrane 1) Trial welding must be carried out before welding work is carried out. The test welding should be carried out on the provided anti-seepage material sample, with a length of no less than 1 meter and a width of no less than 0.2 meters. The test welding should be

There are many geomembrane production processes, such as: the production process of polyethylene film extrusion blow molding is: put polyethylene resin into the extruder, after the extruder is plasticized and melted, the rotating screw pushes the molten material into the forming mold, and the formed tubular film blank is extruded from the die. out, and

9 Geomembrane laying procedures Artificial membrane laying 1) On general slopes and at the bottom of the site, the laying team members first check whether the number of each geotextile membrane in the laying area is consistent with the number on the layout plan. After confirming that there is no error, they immediately use sandbags
