Bidirectional Plastic Geogrid
1. Bidirectional Plastic Geogrid
The unidirectional stretch geogrid is a type made of high molecular polymer as the main raw material, adding certain UV-resistant and anti-aging additives, and is produced by unidirectional stretching to realign the originally disordered chain-like molecules into a linear state, then extruded into a thin sheet, punched into a regular mesh, and finally stretched longitudinally to form a high-strength geosynthetic material. This process allows the polymer to achieve a directional linear state and form a uniformly distributed, high-node-strength elongated oval mesh structure. This structure has a very high tensile strength and modulus of elasticity, with tensile strength reaching 100-200Mpa, close to the level of low carbon steel, greatly superior to traditional or existing reinforcement materials, especially this type of product has super international-level early (elongation rate of 2%-5%) tensile strength and modulus of elasticity. It provides an ideal force-bearing and diffusion chain system for the soil. This product has a high tensile strength (>150Mpa), suitable for various soils, and is currently widely used as a reinforcement and consolidation material. Its main characteristics are: high tensile strength, good creep performance, easy construction, and low cost.
Unidirectional Geogrid is made from high molecular polymers (PP or HDPE) that are extruded into thin sheets, then punched into a regular mesh, and subsequently stretched longitudinally. This process allows the polymer to achieve a directional linear state and form a uniformly distributed, high-node-strength elongated oval mesh structure.
Unidirectional stretch geogrid is a high-strength geosynthetic material.
Main Uses
1. Unidirectional Geogrid for reinforcing weak foundations: Geogrids can quickly improve the bearing capacity of foundations and control the development of settlement, effectively distributing the load to a wider base, thus reducing the thickness of the base, lowering construction costs, shortening construction periods, and extending service life.
2. Unidirectional Geogrid for reinforcing asphalt or cement pavements: When laid beneath asphalt or cement layers, geogrids can reduce rut depth, extend the fatigue life of the pavement, and also reduce the thickness of asphalt or cement pavements to save costs.
3. Unidirectional Geogrid for reinforcing embankments and retaining walls: Traditional embankment construction, especially for high embankments, often requires overfilling and the edges are difficult to compact, leading to later slope erosion and collapse instability, while also requiring flatter slopes, occupying more land. Using geogrids to reinforce embankment slopes or retaining walls can reduce land occupation by 20%-50%, extend service life, and lower costs.
4. Unidirectional Geogrid for reinforcing river and sea dikes: Can be made into gabions and used together with geogrids to prevent dikes from being washed away by seawater, causing collapse. Gabions have permeability, which can mitigate wave impacts, extend dike life, save manpower and material resources, and shorten construction periods.
5. Unidirectional Geogrid for landfill treatment: Using geogrids in combination with other geosynthetic materials to process landfills can effectively solve problems such as uneven settlement and gas emissions, and can greatly increase the storage capacity of landfills.
6. Special Uses of Unidirectional Geogrid: Low-temperature resistance. After undergoing 200 cycles of repeated hot and cold at -45℃ to -50℃, all performance indicators meet requirements and have been tested on the Qinghai-Tibet Railway, suitable for northern areas with little to no frost, rich in frost, and poorly frozen soils.
Construction Methods
○ When used for subgrades and pavements, the construction method is the same as that of bidirectional geogrids.
○ When used for reinforcing soil retaining walls, the construction method is as follows:
1. Set the foundation and carry out construction according to the designed wall system; when using prefabricated reinforced concrete panels, generally, they are 12-15 cm thick and supported on prefabricated concrete foundations. The width should not exceed 30 cm, thickness should be no less than 20 cm, and the embedment depth should be no less than 60 cm to prevent frost heave from affecting the foundation.
2. Level the wall base and excavate and level according to design requirements. Soft soil must be compacted or replaced, compacted to the required density, slightly exceeding the wall range.
3. Layer the reinforcement materials, with the main strength direction of the materials perpendicular to the wall, fixed with pins.
4. Fill the wall with soil using machinery, maintaining a distance of at least 15 cm between the wheels and the reinforcement materials. The thickness of each layer after compaction is about 20-15 cm.
5. During wall construction, the wall surface should be wrapped with geotextile to prevent soil loss.
Bidirectional Geogrid is made of polyethylene or polypropylene through the processes of extrusion, sheet formation, and punching, followed by longitudinal and transverse stretching.
Welded Plastic Geogrid
Bidirectional welded geogrid is a new type of eco-friendly green building material that adds reinforcing fibers to polyethylene and polypropylene stretching tapes and then welds them into a “#” structure. It can be divided into single and double-directional adhesive and welded geogrid. This product features high strength, low deformation, corrosion resistance, long lifespan, easy and quick construction, low cost, etc., and can be laid flat and positioned evenly, especially meeting the requirements for use in various long-term projects for over 100 years.
2. Unidirectional Plastic Geogrid

3. Knitted Polyester Geogrid
Knitted polyester geogrid uses high-strength polyester fibers as raw materials. It adopts a knitted directional structure, with the warp and weft yarns in the fabric being in a straight state without bends, and the intersection points are bound together with high-strength filament, forming strong bonding points that fully utilize its mechanical properties. High-strength polyester knitted geogrid has high tensile strength, small elongation, strong tear strength, small longitudinal and transverse strength differences, UV aging resistance, wear resistance, corrosion resistance, lightweight, and strong interlocking with soil or gravel, playing a significant role in enhancing soil shear resistance and improving the integrity and load-bearing capacity of the soil.
4. Steel-Plastic Composite Geogrid
Steel-plastic geogrid is made of high-strength steel wire, specially treated, combined with PE, and adding other additives, through extrusion to become composite high-strength tensile strips, with a rough texture on the surface, forming a high-strength reinforced geogrid. This single strip is then woven or layered through longitudinal and transverse spacing, using special enhanced bonding technology to weld its junction points.
Fiberglass Geogrid
5. Fiberglass Geogrid
Fiberglass geogrid is made of fiberglass, utilizing a certain weaving process to create a mesh structure material, and is treated through a special coating process to protect the fiberglass and enhance overall performance, making it suitable for road reinforcement materials.
Grass Planting Grid Base Composition
Many residential areas have roads adjacent to green belts, where grass is usually laid to the roadside; many green areas suffer from severe soil compaction due to poor management. The emergence of grass planting grids solves this problem effectively. Moreover, grass planting grids are widely used in fire lanes and parking lots. They help increase green land, improve ecological environment and safety. Below is some analysis of the construction and maintenance experience of grass planting grids for peer communication and reference.
The base composition of grass planting grids mainly includes the following schemes:
1. Raw soil compaction + gravel + gravel + grass planting grid + mixed nutrient soil
2. Raw soil compaction + gravel + concrete base + gravel + grass planting grid + mixed nutrient soil
3. Raw soil compaction + gravel + concrete base + gravel + non-woven fabric + grass planting grid + mixed nutrient soil
From the analysis of construction cases, we conclude the following: The first scheme allows for smooth drainage, but over time, due to ground load, the surface is prone to collapse; the second scheme easily causes nutrient soil loss due to rainwater erosion over time; after technical discussions and combining experiences of vertical greening, we advocate the third scheme, adding a non-woven fabric layer, which can not only prevent nutrient soil loss but also retain water.
1 Characteristics Introduction Edit

2. Savings: Grass grids combine parking and greening functions, saving valuable space for developers in land-scarce urban areas.
3. Smooth and Complete: The unique and stable flat interlocking of grass grids makes the entire laying surface form a smooth whole, avoiding local depressions, and construction is extremely convenient. (Reference: Concrete grass bricks are independent, requiring a concrete base to maintain flatness)
4. High Strength, Long Lifespan: Grass grids use patented technology with special materials, capable of withstanding pressures of up to 200 tons/square meter, exceeding the regulatory requirements for fire-fighting access of 32 tons/square meter.
5. Stable Performance: UV resistance, acid and alkali corrosion resistance, wear resistance, and weather resistance from -40℃ to 90℃. (Reference: Concrete grass bricks are easily cracked and damaged with temperature changes and frost)
6. Excellent Drainage: The gravel load-bearing layer provides good drainage capabilities, facilitating the discharge of excess rainfall.
7. Protecting the Lawn: The gravel load-bearing layer provides a certain water retention function, beneficial for grass growth, allowing grass roots to grow into the gravel layer. (Reference: Concrete grass bricks have very little space, and temperatures can exceed 50 degrees in direct sunlight)
8. Green and Eco-Friendly: Grass grids are safe, stable, recyclable, and pollution-free, fully protecting the lawn.
9. Lightweight and Economical: Grass grids weigh only 5 kg per square meter, extremely lightweight, quick to install, saving labor and shortening construction periods. (Reference: Concrete grass bricks weigh 250 kg per square meter)

10. Excellent Load-Bearing Effect: Can withstand weights of over 200T/square meter
3 Base Treatment Edit
Base treatment for parking spaces with grass grids:
1. The base soil should be compacted in layers, with a compactness of over 85%; for soft plastic-flowing silt layers, it is recommended to fill with block stones and compact them to solidity.
2. Set a 150 thick sand and stone cushion layer. The specific method is mixing 10% medium coarse sand, 60% crushed stone with a particle size of 20-40, and 30% clay soil, leveling and compacting them to solidity.
3. Set a 60 thick stabilization layer (also serves as a planting layer). The stabilization layer consists of 25% crushed stone with a particle size of 10-30, 15% medium-coarse river sand, and 60% tilled soil mixed with appropriate organic fertilizer, thoroughly mixed and spread on the sand and stone cushion, compacted to solidity, serving as the base for grass grids.
4. Sprinkle a small amount of organic fertilizer on the base layer, manually lay the grass planting grids. The dimensions of the grass grids are designed according to the size modulus of the parking space, generally not needing to be cut; when the parking space has special shape requirements or has sewage manhole covers, the grids can be trimmed to fit the different shapes of the parking space.
5. In the recessed planting grooves of the grass grids, sprinkle planting soil and evenly sweep it into the holes of the grass grids; the height of the soil layer should be lower than the plane of the grass grids by 5-10mm.
6. Lay turf or sow seeds on the planting soil layer of the grass grids. When laying turf, compact the turf onto the planting soil. Water to maintain until the grass takes root, then parking can commence.
For fire lane base treatment with grass grids:
1. When laying grass grids on fire lanes, the compactness of the base soil should meet the design requirements of general concrete fire lanes.
2. The gravel cushion layer and stone powder stabilization layer methods should also comply with the design requirements of ordinary concrete fire lanes.
3. An 80 thick planting soil layer should be applied on top of the stone powder stabilization layer. The soil layer consists of 30% crushed stone with a particle size of 10-30, 15% medium-coarse river sand, and 55% tilled soil mixed with appropriate organic fertilizer, thoroughly mixed and spread on the compacted stone powder stabilization layer, compacted to solidity, serving as the base for grass grids.
4. Lay grass grids and plant grass on the grass grid base.
5. Notably, if the fire lane serves as the main passage for regular vehicles, due to frequent and fast vehicle movement, this is detrimental to the use of grass grids and the normal growth of grass, negatively affecting greening rates and aesthetics. In this case, we recommend that the main vehicle traffic roads still use concrete pavement, only using grass grids on surfaces where fire trucks will occasionally pass in emergencies. Similarly, for the main access roads in parking lots, concrete pavement is recommended, while parking spaces can utilize grass grids for greening.
For pedestrian path base treatment with grass grids:
1. The original base should be compacted.
2. Lay the grass grids on the compacted base soil surface.
3. In the recessed planting grooves of the grass grids, sprinkle planting soil and evenly sweep it into the holes of the grass grids; the height of the soil layer should be lower than the plane of the grass grids by 5-10mm.
4. Lay turf on the grass grids. When laying turf, compact it onto the planting soil. Water to maintain until the grass takes root, then usage can commence.
4 Construction Precautions Edit
1. The gravel base requires compaction, considering the substantial load it bears; the surface must be flat, ideally with a drainage slope of 1%-2%. Water drainage holes in the concrete base should be filled with pebbles or gravel and sand to prevent soil loss.
2. Each grass grid has interlocking connections, and they should be interlocked during installation. After laying the grass grids, use a small roller or a plate compactor to press over the surface once, and any uneven areas should be adjusted until the surface is level.
3. It is recommended to use nutrient soil to fill the grass grids. When backfilling, water should be applied to enable the soil to settle; use a bamboo broom to evenly sweep the nutrient soil into the holes of the grass grids, ensuring the layer is 5-10mm below the plane of the grass grids.
4. Turf is typically Manila grass, which is foot-resistant and easy to grow. When laying turf, a gap of about 20mm should be left, and the installation should be staggered in a tic-tac-toe pattern. After laying the turf, water thoroughly to soften it, then repeatedly compact the grass roots into the grass grids (several times) to facilitate downward growth.
5. Maintenance should be conducted for one month before parking; if the grass is laid between November and the following March (dormant period), it should be maintained for two months before parking.
6. During use or after the rainy season, if a small amount of planting soil is lost, it can be evenly sprinkled over the grass surface to fill in soil lost due to rainwater erosion.
7. The lawn should be mowed 4-6 times a year, weeds should be removed promptly, and fertilization should be applied. During hot and dry seasons, it is important to water frequently or install automatic watering devices to conduct necessary maintenance management.
