Properties of the new laser welded geogrid made of extruded bars
Extruded polymer bars have been used for tensile strength applications for years. New technologies have extended the range of applications of these bars to soil reinforcement. One of these new techniques is laser welding technology to connect separate extruded bars together. This process results in a very consistent production quality and low strength reduction due the optimum welded area between the bars. Such production technology results in 'welded geogrids'. The new laser welded geogrids combine the properties of both stiff extruded geogrids and flexible geogrids and can be made of various polymers. The welding technique creates rigid connections while the most suited polymer can be selected to fulfil the required properties in the application. Polyester (PET) welded geogrids are used in soil reinforcement for long term applications like steep slopes and segmental block walls. Polypropylene (PP) welded geogrids are used in soil stabilization applications like subbase stabilization of roads on soft soils. This paper presents the two laser welded geogrid types. Their production technology and the results on index tests and performance tests related to their application area.
