Background: Goodbye to Traditional Earthen Ponds If you work in aquaculture, especially shrimp farming (such as Vannamei shrimp), you know how crucial water quality management is. For decades, traditional farmers in Indonesia relied on earthen ponds. But as stocking density targets have risen, earthen ponds have started to show their weaknesses. Pond wall erosion, undetected […]

Geomembrane Installation Steps: 1.0 Subgrade Preparation — The geomembrane installation steps begin with subgrade preparation. The subgrade where the geomembrane will be installed must be level and free of sharp objects. All gravel and roots must be cleared from the work area. A geotextile or protective layer can help keep the geomembrane safe from leaks […]

Geomembrane is a waterproof liner made from HDPE. The material contains carbon black and UV stabilisers so it withstands all weather conditions and a wide range of chemicals. HDPE is also one of the strongest plastics, able to withstand temperatures of 120 degrees Celsius. Before comparing geomembrane price, it helps to understand what drives quality. […]

When choosing geomembrane thickness, remember that a geomembrane is most vulnerable to tears, punctures and impact while it is stored, transported, handled, installed and backfilled. Such events often happen accidentally because of poor workmanship. Common situations include tools dropped on the geomembrane, vehicles driving over an unprotected liner, strong wind getting under the geomembrane during […]

Ever since polymers were first developed as a construction material, engineers have created product variations that make work easier and can be tailored to project needs. Polyethylene was first discovered in 1933 by Fawcett and Gibson using a high-pressure technique. The high-pressure process works at temperatures above 250 degrees Celsius and pressures between 1000 and […]

Geomembrane wrinkles are common when installing a geomembrane. Small wrinkles can crack under pressure. If this simple issue is tolerated, it can lead to significant costs from damage to the geomembrane. What causes geomembrane wrinkles? A geomembrane wrinkles because air becomes trapped under it during installation. At first the geomembrane looks flat, but the trapped […]
