Geogrid is a relatively new direction in the development of building materials. Since its appearance on the market, the geotechnical grid has become a rather popular product that helps to perform various landscape works. This innovation has been successfully used to prevent ground movement, reinforcement, strengthening of slopes, provides strength, long-term operation of parking zones.
- Geogrid - what is it?
- Geogrid for tracks at the cottage or suburban area
- Geogrid for parking
- Geogrid for strengthening slopes
The main characteristics of the geogrid are:
- corrosion resistance, temperature changes;
- obstruction to soil movement;
- providing a comfortable environment for plants( their root system);
- repetition of the soil relief features during laying;
- silting obstruction;
- environmental safety;
- ease of installation or disassembly;
- acceptable cost.
Geogrids - what is it?
A geogrid is a cellular building material made from geosynthetic polymer. Cell size varies depending on the purpose of the grid. The height of the honeycomb, as well as the length or width, may be different. Welded seams of high strength guarantee reliable mounting sections, which are arranged in a checkerboard pattern.
This material under tension creates a stable reinforcing frame for subsequent construction work, during which the cells are filled with rubble, sand, soil or other materials.
For various applications, two types of cellular structures are used - bulk and flat. Volumetric geogrid( or volumetric geogrids) is attached with metal or solid plastic anchors.
The height of the honeycomb of such a material varies from 5 to 30 cm, it has similar indicators diagonally. Volumetric geogrid does not lose its performance for 50 years. The design is resistant to environmental aggression, its installation does not imply any particular difficulties, it is also able to withstand temperatures from -60 to +60 ° C.
The main direction of the geotechnical lattice of the flat type is the mechanical fixation of the material with which the cells are filled. It is characterized by high strength in all directions, capable of withstanding significant static or dynamic loads.
Biaxial geogrid, application:
- for reconstruction, fixing the base of the roadbed of various types( creates a separating and reinforcing layer);
- strengthening the shores of artificial reservoirs;
- in different directions of landscape design;
- in the construction of parking lots or parking lots for cars of any kind.
Geogrid for paths in the country or a country site
This material can be used in the construction of garden paths, as well as to strengthen the existing ones.
To make a solid dirt path, it is enough to have:
- bayonet, shovel shovel;
- wheelbarrow for soil removal;
- crushed stone or small gravel;
- device for manual soil tamping;
- coil of rope, pegs( to mark the boundaries);
- geotextiles( optional);
- geogrid with appropriate anchors.
The boundaries of the track are marked with pegs, and the width of the future border must be taken into account. According to the planned design, there may be no border, but it must be borne in mind that its presence provides protection against deformation.
Next, the soil layer is removed, the “working surface” deepens. The depth of the trench is usually 25 cm, but if the soil in the area is predominantly clay or peat, then the digging depth can be increased to 30-40 cm.
When the excess soil is removed, the base of the future track is carefully rammed, followed by the laying of the geogrid, its backfilling. If the type of soil on your site is peat, clay or marshy, then it is recommended to place geotextiles( polypropylene and / or polyester geofabric) on the bottom of the trench.
This technique creates additional reinforcement, an obstacle to soil smearing( the base of the future path).
A polymeric geogrid is laid on the geotextile, then it is fixed with anchors. Crushed stone or small gravel is poured into the cells above. After the cells are filled with aggregate, they will no longer be visible, and the output will be a stable coating that will not crumble or shift.
If a curb is implied, then it must be installed before laying the bulk grid, filling it. You should also fill the honeycomb with a significant excess, so that with the subsequent natural subsidence of the filler, it does not sink below the partitions.
Geogrid for tracks in the country is also successfully used for the formation of lawns, which are no longer afraid of soil blurring or subsidence. Do not let the fact that polyethylene is used for the production of this building material does not stop you - it is completely safe for humans, animals and plants.содерж to content ↑
Geogrid for parking
If you set a goal to make everything look aesthetic and attractive at your dacha, then upgrading the access area to the site will not be superfluous. Create a convenient, harmonious, and most importantly - reliable, durable parking will also help geogrid. In this case, a biaxial flat-type lattice, as mentioned above, or bulk modular structures can be used.
Parking is a separate section of soil that will be subjected to loads, so the main task is to strengthen the base of the entrance and parking of cars. In addition, parking should be in harmony with the landscape design of the local area or the site itself.
Ecoparking is a great alternative to asphalt or concrete parking lots thanks to the geogrid, simple technology of its installation.
- The top layer of soil is removed on the area designated for these purposes, approximately 10-15 cm.
- The base is being rammed, 3-5 cm of sand and fine gravel are poured.
- The geogrid for parking is laid on top of the sand and gravel layer. Its fragments are fastened with special locks, screws or pneumatic stitcher.
- Cells are filled with rubble, turf or substrate, depending on the type of parking planned.
- When filling cells with the substrate, you need to look for the fullness level to coincide with the top edge of the cell.
- Ecopark requires regular watering during the growth of grass, at this time it should not be used.
- In all other cases( turf, rubble) parking can be used immediately.

Geogrid for strengthening the slopes
With the help of a geotechnical grid, even slopes with a large or steep slope can be strengthened. In the form of fillers for cells can be used soil, gravel, sand, pebbles, other. It should be borne in mind that the steeper the slope, the greater must be the width of the lateral fragments of the lattice.
The geogrid for strengthening the slopes is the most popular, convenient material for preventing landslides. These cellular structures are reliable, have good stretchability, help to turn areas with complex relief into individual landscape features that have a decorative function.
Geogrid reinforcement - laying steps on a slope:
- Before laying the grid, the slope is as leveled as possible.
- The boundaries of the slope are marked according to the account of the slope.
- Geotextiles are laid on the slope.
- According to the tags, high-strength anchors are installed( 60-90 cm).
- The geogrid is tensioned onto the anchor, the process starts from the tops of the slope.
- The stretched grille is fixed with L-shaped mounting anchors. The installation step for anchors is from 1 to 2 meters.
- At the end of cell fixing, the cells are filled( from top to bottom) with filler. The cells must be filled with a slide of at least 3-5 cm.
Geogrid, which can be bought relatively inexpensively, is a complex technology aimed at preventing leaching, subsidence, heaving of the soil. This building material is successfully used to enhance the carrying capacity of the soil.
Good results are obtained by filling the cells with plants with an active root system. The roots are woven with the lattice itself, fasteners and thereby strengthen the strengthening effect.
Today the geogrid is widely used in private construction, designing design ideas on country sites. Let this innovative material help you to increase the level of comfort at your dacha, to carry out new building plans.
