The types of geomembrane commonly used for ponds are HDPE (High Density Polyethylene) and LLDPE (Linear Low Density Polyethylene) geomembranes. An HDPE geomembrane for aquaculture is a sheet made from high-density polyethylene plastic with a flexible and waterproof structure. HDPE geomembrane used in aquaculture helps reduce the build-up of organic material on the pond bottom. […]

Question: How do you connect a geomembrane to a pipe?Answer: ASTM D6478 provides guidance on how to connect geomembrane to pipe. “Pipe boots are fabricated from geomembrane, and the pipe boots are then joined to the geomembrane by extrusion welding.” The geomembrane is then connected to the pipe using a clamp and rubber gasket. Below […]

Geosynthetics in road construction are quite common, including geotextile, geogrid, geocell, geonet and geomembrane. These geosynthetics can fulfil one or more of the functions a road structure needs. For example, in 1970 geosynthetics were used to improve the performance of roads on soft soil. From 1980 onwards, geosynthetics were developed to reduce the risk of […]

Preventing reflective cracking with geogrid for asphalt is one of the earliest applications of geosynthetics in asphalt roads. Reflective cracks often appear in new asphalt overlaid on existing asphalt that has already cracked. Reflective cracking can occur due to deflection or shear stress caused by repeated vehicle loads. Extreme temperature changes can also cause it. […]

Question: Hello Petra Nusa Elshada, how long does non-woven geotextile material last when installed in the ground as a separator and reinforcement? Answer: Thank you for your question about the non-woven geotextile service life. There are several references on the durability of non-woven geotextile used as a separator. One example is material installed in 1972 […]

Question: What is the difference between woven and non-woven geotextile? Answer:The use of geotextiles has risen sharply over the last few decades. Geotextiles began with textiles already available on the market, such as carpets and upholstery fabrics. Seeing the opportunity, manufacturers started modifying these fabrics into geotextiles that could add value to road construction. There […]
