Geogrids are polymeric products formed by joining intersecting ribs. They have large open spaces, also known as “apertures.” The directions of the ribs are referred to as the machine direction (MD), oriented in the direction of the manufacturing process, or the cross-machine direction (CMD), perpendicular to the machine direction ribs. Geogrids are mainly made from polymeric materials, including polypropylene (PP), high-density polyethylene (HDPE), polyester (PET) and Fiberglass.
Product Information
PP Geocomposite is a flat composite geogrid from the polypropylene geocomposite product range. Incorporated into the geogrid construction is a non-woven geotextile component for specific applications where reinforcement of problematic soils is required, combined with the additional functions of separation and filtration. This combination provides reinforcement, stabilisation, filtration, separation, and drainage in a single product.
The unique manufacturing process produces structured, high-strength, monolithic, pre-stressed polypropylene, or polyester bars with a continuous molecular structure. The extraordinary high extensional stiffness of PP geocomposite efficiently reduces deformations in the subgrade, which extends the service life of modern infrastructure.
Applications
Geogrids play a crucial role in renewable energy projects, offering environmental protection, cost efficiency, and operational advantages for sustainable development worldwide. The global investment in renewable energy has seen significant growth, with wind energy emerging as the fastest-growing sector. Geosynthetics, including geogrid reinforcement, have played a vital role in enabling the construction of these projects, particularly wind farms.
Accessing renewable wind energy often presents engineering challenges due to complex terrain and soil characteristics. Wind farms require expansive areas with stable soil conditions for construction, including access roads and turbine pads. Geogrid reinforcement, such as Polypropylene Geocomposite, proves indispensable in providing soil stability and facilitating access to wind farm sites.
The utilisation of geosynthetics, specifically geogrid reinforcement, has contributed to the success and sustainable development of renewable energy projects worldwide. By incorporating high-performance geogrids like PP Biaxial Geogrid and PP Geocomposite into these projects, engineers can overcome access challenges, enhance soil stability, and promote the efficient utilisation of renewable energy resources.
Features and Benefits
PP Geocomposite stands out by combining reinforcement with additional engineering functions required in the reinforcement layer, including separation, filtration, and drainage. This composite product integrates a PP biaxial geogrid with a needle punched nonwoven geotextile. The geotextile is firmly welded between the reinforcement bars, offering exceptional support for soil stabilisation, separation, and filtration. Moreover, PP Geocomposite exhibits an interlocking behaviour equivalent to that of PP biaxial Geogrid due to its unique manufacturing process.
PP Geocomposite offers distinctive features such as excellent separation, filtration, and drainage characteristics, making it particularly suitable for subsoils with a CBR value of less than 3%. It provides remarkable performance in reinforcing base courses, working platforms, temporary access roads, paved roads, and pipeline trenches. Large-scale laboratory tests have demonstrated its exceptional durability, preventing deep traffic ruts even after a significant number of load cycles.
By incorporating Combigrid® into infrastructure projects, engineers can benefit from its superior reinforcement properties, enhanced soil stability, and multifunctionality. It enables efficient utilisation of renewable energy resources, while contributing to sustainable development and long-lasting infrastructure.
