1. Applicable to most slopes and embankments composed of rocky and unconsolidated soils.
2. Allows increasing the distance between adjacent anchors up to 3.5 m, reducing the overall project cost.
3. 2D-GEO meshes are tested on specialized test benches and certified in accordance with Russian Federation standards.
4. Allows for additional loads and external factors to be taken into account.
5. All system elements are individually selected for each specific slope.
6. Grass seeding and the preservation of woody vegetation on the slope are possible.
7. Short steel spirals are convenient to install and allow multiple mesh cells to be connected in a single step.
8. Geobarrier cable anchors with centralizers can be inserted into the borehole in a single step.
9. The pin anchor plate matches the technical specifications of the 2D-GEO mesh range.
10. Materials, components, and accessories for the 2D-GEO system are manufactured in Russia.

Application of the 2D-Geo System

The 2D-Geo landslide protection system provides landslide and rockfall protection for the area and can be applied to slopes composed of rock and unconsolidated soils. The main structural element is the high-strength 2D-Geo steel mesh, which is installed on anchors or soil nails using spike anchor plates.

Around the perimeter of the reinforced area, the system is tensioned with steel ropes secured to flexible cable anchors. Adjacent panels of neighboring mesh rolls, overlapped by two cells, are fastened together with steel spirals.

Active Engineering Protection

The 2D-Geo system belongs to active engineering protection methods. When the spherical nut on the anchor is tightened, the spike anchor plate presses the mesh tightly against the ground surface. The mesh actively impacts the surface and prevents the slope from losing its equilibrium, preventing the fall of unconsolidated soil and rock blocks along the detachment planes between the anchors.

Anchors and Configuration Selection

The overall stability of the slope is ensured by ground anchors or soil nails grouted in the borehole. The length and diameter of the anchors are selected based on the depth of the failure prism boundary and the soil type. Most often, bar and drilled-and-grouted ground anchors are used with the 2D-Geo system.

The 2D-Geo system consists of numerous elements of various modifications and is individually tailored to the specific geotechnical conditions of the slope. A wide selection of 2D-Geo meshes with a tensile strength of up to 155 kN/m allows for the selection of an effective configuration with maximum performance and economic benefit.

Landscape Preservation

The 2D-Geo landslide protection system, with its large mesh cells, preserves the aesthetic appearance of the landscape in its natural beauty, which is especially relevant for recreational complexes and nature parks.
