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
HDPE geomembrane welding requirements The HDPE geomembrane process is the most critical process in the entire anti-seepage system. The success or failure of the entire project depends on the construction quality of the artificial geomembrane. Therefore, in the construction, every process and every link must be strictly organized and carefully constructed. HDPE geomembrane welding generally
9 laying methods of geotextile: The geotextile roll should be protected from damage before installation and deployment. The geotextile rolls should be stacked in a leveled place without water accumulation, the stack height should not exceed the height of four rolls, and the identification sheet of the roll can be seen. Geotextile rolls must be
HDPE geomembrane construction process 1. Process flow ●Foundation excavation ●Do lake bottom mortar protective layer (H20-30mm) ●Slope cutting, compaction and leveling ●Paste composite geomembrane and vertical retaining wall ●Basal surface leveling, cleaning, process handover ●Seal and stop water at the mouth of the underwater water pipe ●Composite geomembrane laying and welding ●Process handover ●Welding and
As a geosynthetics buyer or wholesaler, you may be wondering about the differences between geogrids and geonets. It’s essential to understand how they are similar and how they’re different in order to make the right purchase for your project. But never fear – this article is here to explain these two types of products in
