Geogrids come in a variety of types, whether that is in non-woven, or specialty forms.
Extruded geogrids are one such type that is used in many different types of construction projects to accomplish specific tasks.
These types of geogrids are manufactured by pushing molten polymer (such as polypropylene (PP) or high-density polyethylene (HDPE)) through a mold or die, creating a solid sheet with openings. The sheet is then stretched in one or more directions to improve its strength or stiffness.
These extruded geogrids are used for a variety of functions, since they are designed to strengthen and stabilize soil or aggregate layers in civil engineering projects. That leads us to their first function: reinforcement. Extruded geogrids provide tensile strength to weak soils, helping them interlock with the grid’s openings, creating a stronger composite material. By being able to do that, they also help stabilise the soils, improving the load-bearing capacity of soft and weak soils by spreading the heavy load over a wider area, reducing pressure and preventing movement or displacement. Extruded geogrids also help keep different soil layers from mixing which maintains its structural integrity and drainage properties, which in turn helps to combat erosion.
The reason as to why extruded geogrids are used for these functions over other types of geogrids is due to a number of factors. The first and core factor is due to the grid’s high tensile strength, which allows the extruded geogrid to resist strong pulling forces without breaking, which is an integral factor when it comes to supporting soils under heavy loads.
Due to the materials these geogrids are made from, they also possess a long lifespan with their durability and resistance to chemicals, ensuring long-term performance across the projects they are used in. The openings that are present on the geogrid also help, as they allow soil or aggregates to lock into the grid. Furthermore, extruded geogrids are not only strong, they’re flexible, which helps them adapt to ground movements, preventing any cracks of failures in roads, slopes, and walls.
With these properties in mind, extruded grids are used in many different areas over woven or knitted ones. These areas can include roads, highways, retaining walls, slopes, and areas with heavy loads, making extruded geogrids relatively high in demand. For contractors searching for high-quality and reliable geogrids, NovaGeo offers NovaGrid, providing woven, non-woven, and extruded geogrids that are specially made with proven experience out in the field, ensuring long-term durability and lowering operation and installation costs.
