Polymeric geogrid is a mesh synthetic material resembling honeycombs. The basis is polyethylene tapes and needle-punched polyester fabric, for the connection of which reliable welded seams are used. The greatest distribution is observed in the construction of civil facilities, in industry and when laying the roadway. There is also a massive use of the material as a reinforcing layer in landscape design projects. Various building materials are used to fill the honeycomb - it can be sand, gravel or soil.
3D geogrid: advantages
Long period of operation is the main positive point. There is no need to replace it for 50 years, while not being affected by any environmental conditions, the service life does not change with a wide temperature range and high humidity levels. Also, the mesh is easy to install and resistant to decay. Geogrid volumetric simplelaid out on the ground and filled with the selected backfill. For best performance, laying should be done on well-packed soil.
Due to the long period of use, the mesh pays for itself in a short time. Forming a standard retaining wall structure to reinforce a slope prone to landslides will cost significantly more and take longer, as well as slope stabilization. Among the advantages, it should be noted that there is no need for repairs, which the wall cannot boast of.
The grate is indispensable for the construction of objects of various types, it prevents the soil layer from slipping near water bodies and on slopes, and helps to strengthen the soil surface.
Views
There are two types of mesh - flat and voluminous. Volumetric geogrid for slopes is a material of tapes fastened together with a cellular three-dimensional structure. Modules are formed from the cells under tension. The anchor is used to secure them by stretching and giving a rectangular shape. The anchor is based on composite, metal or plastic materials. The plastic element is resistant to corrosion changes, light in weight, but at the same time it does not tolerate low temperatures and is quite fragile, which makes it impossible to use it in dense soil. Strong steel acts as a material for a metal anchor. The greatest functionality is noted in complex soil. But over time, such anchors formcorrosion. The fiberglass used to make composite elements is fracture-resistant, strong and lightweight.
Application
The geogrid, which is priced to fit any budget, is firmly connected with double seams that form a three-dimensional structure in a set sequence. When folded, it forms compact modules that, when unfolded, form a canvas with a three-dimensional honeycomb base of given dimensions and a geometrically defined shape.
High-efficiency anchoring technology and flexible design make landscaping work much easier, as well as high-angle slopes and slopes. The integrity of the ground layer is ensured by gratings due to the resistant material used. The steep slope surface, characterized by erosion and lack of landscaping due to the use of mesh, turns into a stable basis for green spaces.
The use of this material makes it possible to stabilize the surface in contact with the bulk base, while increasing the resistance of slopes to erosion.
Features
The plane in need of strengthening should have a layer of fertile vegetative soil with seeds of perennials, as an option, it is possible to use a hydroseeder after the cells are filled with a vegetative layer of soil.
Prevention of erosion by precipitation is possible by using a protective layer resistant to erosion. Also, a geogrid, the price of which is an average of 2000 rubles per 10 square meters. m, it is effective in pipe bunding, arranging wall retaining structures and strengthening road foundations.
The material is sold in the form of rolls, which are characterized by a rather low weight, which greatly facilitates transportation to the construction site. Cell size has a direct effect on overall dimensions.
Backfill for cells
As a filling, a volumetric geogrid can have the following materials, which are selected in accordance with the requirements of the project and priorities:
- combined;
- soil filling (soil can be used from any space, regardless of the presence or absence of vegetation);
- filling (concrete);
- bulk (sand or gravel of any fraction).
How to install the grille
Requires preliminary leveling of the site with the strengthening of the soil and giving the necessary shape. Geotextiles and other materials can act as a drainage layer.
The volumetric geogrid is laid on surfaces with a steep slope from top to bottom. The height of the mesh edges depends on the steepness of the slope. After that, the module is straightened and fixed with stakes or special anchors.
For filling it is not necessary to use a loader, in most cases the soil material is distributed manually. seedsvarious herbs are used to form the turf layer.
