Geogrids are three-dimensional polymeric. Features & Specs

Geocell polymeric is a reticular synthetic material that resembles honeycombs. The basis is made of polyethylene tapes and needle-punched polyester web, for the connection of which welded reliable seams are used. The greatest distribution is observed in the construction of civilian objects, in industry and in the laying of roads. There is also a mass application of the material as a reinforcing layer in landscape design projects. Various building materials are used to fill honeycomb - it can be sand, crushed stone or ground.

Geogrids are three-dimensional: advantages

A long period of operation is the main positive point. The need to replace it is absent for 50 years, without affecting any environmental conditions, the service life does not change under the extensive temperature range and high humidity level. Also, the grid is easy to install and resistant to decay. Geogrids are simply laid out on the ground and filled with the selected backfill. To improve performance, laying should be done on carefully compacted soil.

Due to the long period of use, the grid pays off in a short time. The formation of a standard retaining wall structure to strengthen the slope, subject to landslides, will cost significantly more and take more time, as well as strengthening slopes. Among the advantages it should be noted that there is no need for repairs, which the wall can not boast.

Lattice is indispensable in the construction of objects of various types, prevents the slipping of the soil layer near the ponds and on the slopes, contributes to the strengthening of the ground surface.

Kinds

There are two types of grid - flat and three-dimensional. Geogrids for slopes Volume is a material of tapes fastened together, with a cellular three-dimensional structure. From the cells, the modules are formed under tension. Anchor is used to fix them by stretching and giving a rectangular shape. The basis of the anchor is composed of composite, metal or plastic materials. The plastic element is resistant to corrosive changes, light weight, but it does not tolerate a low temperature regime and is fragile enough, which makes its application impossible in dense ground. The material for the metal anchorage is durable steel. The greatest functionality is noted in complex soil. But over time, corrosion is formed on these anchors. Fiberglass, used for the manufacture of composite elements, is resistant to breakage, strength and ease.

Application

Geogrid, the price of which allows it to be used when working with any budget, has a strong connection by double seams that form a three-dimensional structure in the established sequence. When added, it forms compact modules that form a decomposed web with a three-dimensional honeycomb base of specified dimensions and a geometric shape.

Highly efficient fastening technology with anchors and a flexible design greatly simplify the work on gardening, and also allow the strengthening of slopes and slopes with a large angle. The integrity of the ground layer is ensured by gratings due to the stable material used. The steep slope surface, characterized by erosion and lack of landscaping due to the use of a grid, turns into a stable base for green plantations.

The use of this material makes it possible to stabilize the surface when it comes into contact with a bulk foundation, while the resistance of slopes to erosive phenomena increases.

Features

A plane that needs to be strengthened must have a layer of fertile plant soil with seeds of perennial plants, as an option it is possible to use a hydroseater after the cells are filled with a vegetative layer of soil.

Prevention of erosion by precipitation is possible when using a protective layer that is resistant to erosion. Also a geogrid, whose price is on average 2000 rubles per 10 sq. Km. M, is characterized by efficiency at pipe embedding, arrangement of wall retaining structures and hardening of the foundations of roads.

The material is realized in the form of rolls, differing by a rather small weight, due to which the transportation to the object of erection is much easier. The size of the cells has a direct effect on the overall dimensions.

Backfilling for cells

As a filling, a bulk geogrid can have the following materials, which are selected in accordance with project requirements and priorities:

• Combined;
• Soil backfilling (soil can be used from any space, regardless of the presence or absence of vegetation);
• Bulk (concrete);
• Bulk (sand or gravel of any fraction).

How to install a grate

A preliminary alignment of the site with hardening of the soil and shaping is required. As a drainage layer, geotextiles and other materials can act.

The geogrid is laid volumetric on surfaces with a steep slope from top to bottom. The height of the edges of the grid 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 the loader, in most cases the ground material is distributed manually. Seeds of various herbs are used to form the turf layer.
