Geogrid is a type of geosynthetics. Made from polyethylene and polypropylene strips. The product is a multidimensional honeycomb structure. The raw material is resistant to direct sunlight, significant temperature changes and aggressive chemicals.
Described by us polymer geogrid belongs to a wide class of reinforcing materials. By its structure, the material is a set of strips that are joined by high-strength welding seams. The thickness of the strips does not exceed 2 mm, and the height is from 50 to 200 mm. The size of the cells is chosen depending on the purpose of the products and the operating conditions of the product.
Applications
The geogrid is used to strengthen the surface of loose soil in order to prevent the development of soil erosion. It is widely used as a reinforcing material for the protection of slopes and foundations, coastal zones, coastal areas of rivers, reservoirs and canals.
Polymer Geogrid Laying Technology
Installation is carried out in several stages. First, they prepare the site, mark the territory, remove all vegetation from it and remove the layer of soddy soil. The surface is carefully leveled. In areas prone to flooding, geotextile sheets are laid, which prevents the mixing of the parent soil with the backfill material and acts as a drainage.
The next stage is the laying of the geogrid. The method of connecting the elements is selected at the stage of project development. Separate modules are attached to the soil surface and to each other with L-shaped anchors.
The finished structure is filled with a homogeneous filler: crushed stone, soil, as well as frost-resistant concrete. The layer thickness above the grating is at least 50 mm. Use construction equipment to fill in
