Bidirectional Plastic Geogrid
1. Bidirectional Plastic Geogrid
Unidirectional stretch geogrid is a high-strength geosynthetic material made from high molecular polymer as the main raw material, adding certain UV-resistant and anti-aging additives, and undergoing unidirectional stretching to reorient the originally scattered chain-like molecules into a linear state, extruding into thin sheets, then punching regular holes, and finally longitudinally stretching to form a high-strength geosynthetic material. This process enables the high polymer to achieve a directional linear state and forms a uniformly distributed, high node strength, elongated elliptical mesh structure. This structure possesses quite high tensile strength and tensile modulus, with tensile strength reaching 100-200Mpa, comparable to low carbon steel levels, significantly outperforming traditional or existing reinforcement materials, especially having super international levels of early (elongation rate of 2%-5%) tensile strength and tensile modulus. It provides an ideal force-bearing and diffusion chain system for the soil. The product has great tensile strength (>150Mpa), adapts to various soils, and is currently widely used as a reinforcement material. Its main features are: high tensile strength, good creep performance, easy construction, and low cost.
Unidirectional geogrid is made from high molecular polymer (PP or HDPE) by extruding into thin sheets, then punching regular holes, and longitudinally stretching to form. This process leads the high polymer to a directional linear state, forming a uniformly distributed, high node strength, elongated elliptical mesh structure.
Unidirectional stretch geogrid is a high-strength geosynthetic material.
Main Uses
1. Unidirectional geogrid is used for reinforcing weak foundations: geogrids can quickly improve the bearing capacity of foundations, control the development of settlement, and effectively distribute loads across a wider subbase, reducing subbase thickness, lowering project costs, shortening construction time, and extending service life.
2. Unidirectional geogrid is used for reinforcing asphalt or cement pavements: geogrids laid at the bottom of asphalt or cement layers can reduce rut depth, extend the fatigue life of the pavement, and also reduce the thickness of asphalt or cement layers to save costs.
3. Unidirectional geogrid is used for reinforcing embankments and retaining walls: traditional embankments, especially high embankments, often require excessive filling, and the shoulders are difficult to compact, resulting in rainwater infiltration and instability, which can lead to landslides; they also require gentler slopes, occupying large areas. Retaining walls face similar issues; using geogrids to reinforce the slopes of embankments or retaining walls can reduce the land area by 20-50%, extend service life, and lower costs.
4. Unidirectional geogrid is used for reinforcing river and sea dikes: it can be made into gabions and used in conjunction with geogrids to prevent dikes from collapsing due to seawater erosion; gabions are permeable and can mitigate wave impact, extending the lifespan of the dikes, saving manpower and resources, and shortening construction time.
5. Unidirectional geogrid is used for managing landfill sites: geogrids used in combination with other geosynthetic materials for landfill management can effectively address issues of uneven settlement and gas emissions, greatly enhancing the storage capacity of landfills.
6. Special uses of unidirectional geogrids: low-temperature resistance. After 200 cycles of repeated cold and heat at -45℃ to -50℃, all performance indicators meet the requirements and have been tested on the Qinghai-Tibet Railway, suitable for northern areas with low frost soils, frost-rich soils, and poorly consolidated frozen soils.
Construction Methods
○ When used for subgrade and pavement, the construction method is the same as that of bidirectional geogrids.
○ When used for reinforcing earth retaining walls, the construction method is as follows:
1. Set the foundation according to the wall system designed; when using precast reinforced concrete panels, generally 12-15 cm thick, supported on precast concrete foundations, its width should not exceed 30 cm, thickness not less than 20 cm, with a burial depth of not less than 60 cm to prevent frost heave from affecting the foundation.
2. Level the wall base according to design requirements; excavate and level soft soils, which should be compacted or replaced, compacting to the required density, slightly exceeding the wall range.
3. Lay the reinforcement fabric, ensuring the main strength direction is vertical to the wall and fixed with pins.
4. Backfill the wall with mechanically placed soil, maintaining at least 15 cm distance between the wheels and the reinforcement fabric. The compacted soil layer should be approximately 20-15 cm thick.
5. During wall construction, the wall surface should be wrapped with geotextile to prevent soil loss.
Bidirectional geogrids are made from polyethylene or polypropylene by extrusion, forming sheets, punching holes, and then longitudinally and transversely stretching.
Welded plastic geogrid

Grass Planting Grid Base Construction
Many residential areas have roads adjacent to green belts, with lawns typically laid to the roadside. Due to poor management, the soil in many green spaces becomes severely compacted. The introduction of grass planting grids effectively solves this issue, and they are also widely used in fire lanes and parking lots, addressing the increase of green space while improving the ecological environment and safety. Below are some analyses of the construction and maintenance experiences of grass planting grids for peer exchange and reference.
The base construction of grass planting grids mainly includes the following schemes:
1. Solid soil compaction + crushed stone + solid soil compaction + planting grid + mixed nutrient soil
2. Solid soil compaction + crushed stone + concrete foundation + solid soil compaction + planting grid + mixed nutrient soil
3. Solid soil compaction + crushed stone + concrete foundation + solid soil compaction + non-woven fabric + planting grid + mixed nutrient soil
From the analysis of construction cases, we conclude the following: the first scheme provides smooth drainage, but over time, due to surface loads, the ground is prone to collapse; the second scheme is prone to nutrient soil loss due to rainwater erosion over time; based on technical discussions and experiences of vertical greening, we advocate the third scheme, which adds a non-woven fabric layer to prevent nutrient soil loss while also retaining moisture.
1. Feature Introduction 1. Complete Greening: Grass grids provide over 95% planting area, achieving full greening effects, which can absorb sound and dust, significantly enhancing environmental quality and taste. (Reference: Concrete grass planting bricks only have 30% voids)
2. Savings: Grass grids combine parking and greening functions, saving precious space for developers in densely populated cities.
3. Flat and Complete: The unique and stable flat interlocking of grass grids creates a flat surface, avoiding local depressions, and the construction is extremely convenient. (Reference: Concrete grass planting bricks are independent and require a poured concrete base to maintain flatness)
4. High Strength, Long Lifespan: Grass grids use patented special materials, with a compressive capacity of up to 200 tons/square meter, exceeding the standard requirement of 32 tons/square meter for fire emergency access.
5. Stable Performance: UV resistance, acid-base corrosion resistance, wear resistance, and weather resistance from -40℃ to 90℃. (Reference: Concrete grass planting bricks are prone to cracking and damage with temperature changes and frost)
6. Excellent Drainage: The crushed stone load-bearing layer provides good drainage capabilities, facilitating the discharge of excess rainfall.
7. Protecting Lawns: The crushed stone load-bearing layer provides a certain water retention function, beneficial for lawn growth, allowing grass roots to grow into the crushed stone layer. (Reference: Concrete grass planting bricks only have limited space, with temperatures exceeding 50 degrees during summer)
8. Green and Environmentally Friendly: Grass grids are safe, stable, recyclable, and pollution-free, fully protecting lawns.
9. Lightweight and Cost-effective: Each square meter of grass grid weighs only 5 kg, extremely lightweight, quick to install, saving labor and shortening construction periods. (Reference: Concrete grass planting bricks weigh 250 kg per square meter)
2. Construction Features 1. Eco-friendly, non-toxic, and pollution-free, impact-resistant, aging-resistant, and UV-resistant.
2. Wear-resistant, corrosion-resistant, with good flame-retardant properties, and strong planting capabilities.
3. Reduces ground reflection and ground thermal radiation.
4. Reduces sound wave transmission, lowering noise pollution.
5. Reduces dust, purifying the air.
6. Rainwater naturally seeps through, preventing soil loss and eliminating water accumulation.
7. Water, air, and nutrients circulate naturally, preventing soil compaction.
8. Increases green space area · Simple construction, lightweight.
9. Can be freely combined and disassembled, reusable.
10. Excellent load-bearing: can withstand over 200T/square meter weight.
3. Base Treatment for Grass Planting Grids Used in Parking Spaces:
1. The foundation soil should be compacted in layers, achieving a density of over 85%; if it belongs to soft-plastic to flowable silt layers, it is advisable to fill with block stones and compact them tightly.
2. Set a 150 mm thick sand and stone cushion layer. The specific method is: 10% medium coarse sand, 60% gravel with a particle size of 20-40, and 30% clay, mixed evenly, spread and compacted tightly.
3. Set a 60 mm thick stabilization layer (also serves as a planting layer). The stabilization layer is composed of: 25% gravel with a particle size of 10-30, 15% medium coarse river sand, and 60% tilled soil with an appropriate amount of organic fertilizer, mixed evenly, spread on the sand and stone cushion layer, and compacted tightly, which can serve as the base for grass grids.
4. Spread a little organic fertilizer on the base layer, and manually install the grass grids. The dimensions of the grass grids are designed according to the size modulus of the parking spaces, generally requiring no trimming; when the parking spaces have special shape requirements or there are manhole covers, the grass grids can be trimmed to fit different shapes of parking spaces.
5. Sprinkle planting soil into the recessed slots of the grass grids and evenly sweep it into the holes of the grass grids, with the soil layer height set 5-10 mm below the plane of the grass grids.
6. Lay turf or sow grass seeds on the planting soil layer of the grass grids. When laying turf, it should be compacted onto the planting soil. Water and maintain until the grass takes root before parking.
For Grass Planting Grids Used in Fire Lanes:
1. When laying grass grids on fire lanes, the density of the foundation soil should meet the general design requirements for concrete fire lanes.
2. The crushed stone cushion layer and stone powder stabilization layer should also follow the same design requirements as ordinary concrete fire lanes.
3. On the stone powder stabilization layer, a 80 mm thick planting soil layer should be made. The soil layer is composed of: 30% gravel with a particle size of 10-30, 15% medium coarse river sand, and 55% tilled soil mixed with an appropriate amount of organic fertilizer, spread evenly and compacted tightly, which can serve as the base for grass grids.
4. Install grass grids and plant grass on the base layer of the grass grids.
5. It should be noted that if the fire lane serves as the main passage for vehicles, due to frequent and fast vehicle traffic, this is detrimental to the use of grass grids and normal grass growth, adversely affecting greening rates and aesthetics. In such cases, it is recommended that the main vehicle traffic roads continue to use concrete surfaces, while grass grids can be used for surfaces where fire vehicles only enter in emergencies. Similarly, it is recommended that the main traffic roads in parking lots use concrete surfaces, while parking spaces use grass grids for greening.
For Grass Planting Grids Used in Sidewalks:
1. The original base should be compacted.
2. Lay grass grids on the compacted foundation surface.
3. Sprinkle planting soil into the recessed slots of the grass grids and evenly sweep it into the holes of the grass grids, with the soil layer height set 5-10 mm below the plane of the grass grids.
4. Lay turf on the grass grids. When laying turf, it should be compacted onto the planting soil. Water and maintain until the grass takes root before use.
4. Construction Precautions 1. The crushed stone base requires compaction, considering the load-bearing pressure, and the surface should be flat with a 1%-2% drainage slope. The seepage holes in the concrete base must be filled with pebbles or crushed stone and sand to prevent soil loss.
2. Each grass grid has interlocking connections, and they should be interlocked during installation. After the grass grid installation is completed, use a small roller or vibrating plate to press the grass grid surface back and forth; any uneven areas need to be adjusted until the grass grid surface is level.
3. It is recommended to use nutrient soil to fill the grass grid. When backfilling, water should be applied so that the soil can settle, and a bamboo broom should be used to evenly sweep the nutrient soil from the grass grid surface into the holes, with the soil layer height set 5-10 mm below the plane of the grass grids.
4. The turf used is generally Manila grass, which is foot-resistant and easy to grow. When laying turf, leave about a 20 mm gap and stagger the installation in a herringbone pattern. After laying the turf, water thoroughly to soften it, then use a small roller or vibrating plate to press the grass roots into the grass grids (repeatedly), facilitating downward growth of the grass roots.
5. Maintenance is required for one month before parking; if the grass is laid between November and March of the following year (dormant period), it should be maintained for two months before parking.
6. During use or after rainy seasons, if some planting soil is lost, a small amount of soil or sand can be evenly sprinkled from the lawn surface to fill the soil lost due to rainwater erosion.
7. The lawn needs to be trimmed 4-6 times a year, with timely weeding and fertilizing. During hot and dry seasons, regular watering or installation of automatic sprinkler systems is necessary to ensure proper maintenance and management.
