Feicheng Lianyi's advanced geocomposite is manufactured by ultrasonically welding a grid of biaxial polypropylene (PP) straps—oriented in both the machine (longitudinal) and transverse directions—directly to a PP nonwoven geotextile backing. This innovative integration creates a single, unified product that delivers bidirectional tensile strength combined with essential geotextile functions.
Lianyi Polypropylene (PP) triaxial geogrid, manufactured from processes of raw materials feeding, extrusion to sheet, punching to perforation and MD and CMD stretching to acheive required tensile strengthes at mulidirections. The “PP Triaxial Geogrid” is defined as a high-performance geosynthetic material designed with triangular apertures to provide multi-directional reinforcement, improved load distribution, and ground-stabilisation benefits
Lianyi PP Uniaxial Geogrid is especially designed for soil reinforcement. It is manufactured with high quality Polypropylene resins, from the process of extruding and longitudinal stretching. Lianyi PP Uniaxial Geogrid has high tensile strength, excellent interlock capacity and low creep deformation.
PP (Polypropylene) welded geogrid is another type of geosynthetic material used for soil reinforcement, ground stabilization, and various civil engineering applications. Similar to PET welded geogrids, PP welded geogrids are constructed from extruded polypropylene strips that are welded together, often using ultrasonic welding techniques.
PET welded geogrid is a type of geosynthetic material made from extruded polyethylene terephthalate (PET) strips that are heat-bonded together through an ultrasonic welding process. This construction method provides strong and durable geogrids that are used for soil reinforcement, ground stabilization, and other civil engineering applications.
Fiberglass Geogrid Composite with nonwoven geotextile is an asphalt reinforcement composite that fiberglass geogrid with PET Nonwoven geotextile on one side. They are composited together by pressure sensitive glue. The chemistry stability is good, the hot-stability is good, anti-weary dehiscence, anti-low temperature shrinkage crack, postponement reduction reflection crack. The nonwoven simplifies installation and ensures continuous bond between the layers. This excellent adhesion allows Geocomposite to take up and evenly distribute tensile forces.
Steel-plastic composite geogrid is made using high-strength steel wires (or other fibers) that have been specially treated, combined with polyethylene (P.E) and other auxiliary materials. These materials are extruded to form a composite high-strength tensile strip. The surface of the strip has a rough embossed texture, making it a reinforced plastic strip. This single strip is then warp-knitted both longitudinally and transversely. Using special ultra-sonic welding process, the joints are welded to form a reinforced geogrid.
Polyester uniaxial geogrids are specialized geosynthetic materials designed primarily for soil reinforcement in one principal direction. These geogrids are crafted from high-tenacity polyester yarns and coated with a durable polymer, providing exceptional tensile strength and durability. The uniaxial structure makes them particularly effective for applications where reinforcement is required predominantly in one direction, such as retaining walls, slopes, and embankments.
Lianyi PVC coating polyester geogrid is made from high-molecule weight polyester yarn which is a flexible engineering material owns high tenacity, heat resistance and good mesh stability. Polyester geogrid biaxial type is square mesh structure providing tensile strength in both longitudinal (machine direction) and transverse (cross-machine direction) orientations, making them suitable for a variety of construction applications.
Fiberglass geogrid is a new type of geosynthetics material made from high strength E-glass fiber yarn, produced with high quality fiberglass filament and special warp-knitting technology. Fiberlgass geogrid is coated with bitumenious polymer to protect glassfiber and provide mesh dimensional stability. Lianyi fiberglass geogrid provide a full range of tensile strengthes from 30kN/m to 300kN/m which is suitable for reinforcement of soft soil, concrete and asphalt layers.
