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
I. Selection of Storage Location 1. Choose a Dry Place Geotextiles should be stored in a dry area, avoiding areas with accumulated water. For example, a relatively dry corner inside a warehouse can be selected for storing geotextiles. This helps prevent the geotextiles from getting damp due to prolonged exposure to moisture. 2. Avoid Low-Lying
Construction Preparation: Before construction, the foundation needs to be cleaned and leveled to ensure there are no sharp objects or debris. Select appropriate laying methods and fixing techniques based on project requirements. Laying and Welding: HDPE geomembrane should be connected using hot-melt welding to ensure the strength and tightness of the seams. During the laying

what is pond lining material ？ Pond lining materials are crucial for creating water-tight ponds and preventing water leakage. There are various types of pond liners available, each with its own characteristics, advantages, and suitability depending on the pond’s purpose and environmental factors. Here are some common pond lining materials: 1. EPDM (Ethylene Propylene Diene
What is geomembrane？ A geomembrane is a type of synthetic membrane with a very low permeability, used primarily as a barrier to prevent the movement of fluids, gases, or contaminants. Geomembranes are commonly made from polymeric materials such as high-density polyethylene (HDPE), polyvinyl chloride (PVC), low-density polyethylene (LDPE), and ethylene propylene diene monomer (EPDM), among
The HDPE geomembrane installation 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 anti-seepage layer. Therefore, every process and every link during construction must be strictly organized and constructed carefully. HDPE geomembrane construction technical requirements Before laying
