Combigrid® Multi-Functional Geogrid – High-Performance Soil Reinforcement

Combigrid® Multi-Functional Geogrid – Advanced Soil Reinforcement Solution
Combigrid® is a high-performance geogrid designed to tackle complex soil reinforcement challenges. By combining the robust strength of Secugrid® geogrid with a non-woven geotextile, Combigrid® offers a comprehensive solution for soil stabilization, separation, filtration, and drainage. This versatile product is ideal for infrastructure projects requiring enhanced soil support and longevity.
Overview
Combigrid® is constructed using high-strength polymeric materials such as polypropylene or polyester, forming a grid with large apertures. This unique design ensures superior soil reinforcement, making it a reliable choice for challenging construction environments. The integrated geotextile adds extra layers of functionality, including separation and filtration, ensuring long-lasting stability in a variety of applications.
Applications
Combigrid® is perfect for infrastructure projects like road construction, wind farm access, and crane platforms. Its high extensional stiffness minimizes ground deformation, offering durable support even in weak soil conditions. Combigrid® is particularly effective in renewable energy projects, helping to stabilize access roads and foundations in wind farms, contributing to the sustainable development of these critical infrastructures.
