Reservoir vs Embung: What Is the Difference?
Reservoirs and embung (small retention reservoirs) are sometimes still confusing because they look the same. Here is reservoir vs embung explained: A reservoir is a very large artificial lake or pond for storing water. Reservoirs hold water that people can use for drinking water, irrigation, power generation and aquaculture. A reservoir is built by constructing […]
Geomembrane Pipe Boot Design for Leak Resistance
There are many variations of geomembrane boots. This article focuses on the most common type of geomembrane pipe boot and describes in detail the common problems and proposed solutions for achieving leak resistance. Many other variations of geomembrane boots and structures that have been or will be built in the field are not specifically discussed […]
Types of Geomembrane and Their Differences
Polyethylene geomembranes have been widely used as liquid or vapor barriers in many applications. Among the types of geomembrane available on the market are polyvinyl chloride (PVC), chlorinated polyethylene (CPE), chlorosulphonated polyethylene (CSPE), ethylene propylene rubber (EPDM), polypropylene (PP), LLDPE, medium-density polyethylene (MDPE), HDPE, bituminous geomembrane, etc. LLDPE and HDPE are often chosen for geomembranes […]
Geomembrane Seaming Methods for HDPE and PVC
Geomembrane seaming must follow the Indonesian national standard regulations (Bina Marga SKh 1.3.8). The seaming rules include: The geomembrane must be overlapped by at least 14 cm HDPE geomembrane can be joined with 2 types of seam: A. Dual Track Hot Wedge for straight seams Read Also Geomembrane Sizes and Specifications B. Extrusion Fillet Seam […]
How to Choose Geosynthetics for Biogas Containment
Biogas from waste stabilization ponds, typically used to treat wastewater from livestock farms and industry, is a smart, sustainable and environmentally responsible choice. A key component of these systems is the geosynthetics for biogas sealing. Why is HDPE geomembrane the right choice? The value of capturing biogas is becoming clearer as the energy crisis and […]
Geomembrane Heat Resistance at Extreme Temperatures
Prolonged exposure to very high temperatures can weaken a liner quickly. Geomembrane heat resistance matters here: special high-temperature liners can help overcome this problem. Typically, high temperatures over a long period cause a liner to weaken quickly; exposure above 140°F (60°C) can damage the liner.
