1. Bidirectional Plastic Geogrid
Unidirectional stretch geogrid is a high-strength geosynthetic material made from high polymer as the main raw material, adding certain UV-resistant and anti-aging additives, and stretching unidirectionally, which rearranges the originally dispersed chain molecules into a linear state. It is extruded into thin sheets and then punched into a regular mesh, followed by longitudinal stretching to form a high-strength geosynthetic material. This process makes the polymer oriented in a linear state and forms a uniform distribution with high joint strength in a long elliptical mesh structure. This structure has a high tensile strength and tensile modulus, with tensile strength reaching 100-200 MPa, close to that of low carbon steel, greatly outperforming traditional or existing reinforcement materials. Particularly, this product has an ultra-international-level high early (elongation rate of 2%-5%) tensile strength and tensile modulus, providing an ideal force-bearing and diffusion link system for the soil. This product has high tensile strength (>150 MPa), is suitable for various soils, and is currently a widely used reinforcement material. Its main features are: high tensile strength, good creep performance, easy construction, and low cost.

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. The lateral confinement effect on the road base can effectively distribute the load over a wider sub-base, thus reducing the thickness of the base layer, lowering project costs, shortening construction periods, and extending service life.
2. Unidirectional geogrid 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 pavement to save costs.
3. Unidirectional geogrid for reinforcing embankments and retaining walls: Traditional embankments, especially high embankments, often require overfilling, and the edges of the embankments are difficult to compact, leading to risks of slope collapse and instability due to rainwater infiltration. Additionally, a gentler slope is required, taking up more land. Retaining walls have similar issues. Using geogrids to reinforce the slopes of embankments 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: It can be made into gabions and used in conjunction with geogrids to prevent dikes from being washed away by seawater, causing collapse. Gabions have permeability, which can mitigate wave impact and extend the life of the dike, saving manpower and resources, and shortening construction time.
5. Unidirectional geogrid for landfill management: Geogrids combined with other soil synthetic materials for landfill management can effectively solve uneven settlement and gas emission issues, greatly enhancing the landfill's storage capacity.
6. Special uses of unidirectional geogrids: Low-temperature resistance. After 200 cycles of repeated cold and hot at -45℃ to -50℃, all performance indicators meet requirements and have been tested on the Qinghai-Tibet Railway, making them suitable for the less frost-prone soils in the north, soils rich in frost, and poorly conditioned frozen soils.
Construction methods
○ When used for foundations and pavements, the construction method is the same as that for bidirectional geogrids.
○ When used for reinforcing soil retaining walls, the construction method is as follows:
1. Set the foundation and construct according to the designed wall system. When using prefabricated reinforced concrete panels, they are generally 12-15 cm thick, supported on prefabricated concrete foundations. The width should not exceed 30 cm, thickness not less than 20 cm, and buried depth not less than 60 cm to prevent frost heave from affecting the foundation.
2. Level the wall base, excavate and level according to design requirements. Soft soil must be compacted or replaced, compacted to the required density, extending slightly beyond the wall area.
3. Place the reinforcement materials; the main strength direction of the materials should be perpendicular to the wall and fixed with pins.
4. Fill the wall with earth using machinery; the distance between the wheels and the reinforcement materials should be at least 15 cm. After compaction, the thickness of one layer of soil should be about 20-15 cm.
5. During wall construction, the wall surface should be wrapped in geotextile to prevent soil loss.
Bidirectional geogrid is made from 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 building material that enhances the reinforcement of polyethylene and polypropylene stretch bands with reinforcing fibers and then welds them into a “#” structure, which can be divided into single and double-sided adhesive or welded geogrids. This product has the advantages of high strength, minimal deformation, corrosion resistance, long service life, and ease of construction, meeting the usage requirements for various engineering projects for over 100 years.
2. Unidirectional plastic geogrid
Unidirectional plastic geogrid is made from polyethylene, extruded into thin sheets and then punched into a regular mesh, followed by longitudinal stretching. This process makes the polymer oriented in a linear state and forms a uniform distribution with high joint strength in a long elliptical mesh structure.
Uses:
● River dikes, lake embankments, tailings dams, sewage dams and storage areas, channels, and liquid storage pools (pits, ponds)
● Subways, basements, and tunnels, seepage-proof linings.
● Foundation and other saline seepage prevention. Geogrid specifications
● Horizontal seepage-proof cover in front of dikes and dams, vertical seepage-proof layers for foundations, construction cofferdams, waste sites.
● Saltwater and freshwater aquaculture.
● Roadbed for highways, railways; waterproof layers for expansive soils and collapsible loess.
● Roof seepage-proofing.
3. Knitted polyester geogrid
Knitted polyester geogrid uses high-strength polyester fiber as raw material. It employs a knitted directional structure, where the warp and weft yarns in the fabric are in a straight state, and the intersection points are bound together with high-strength fiber filaments, forming strong bonding points, fully utilizing its mechanical properties. High-strength polyester knitted geogrid has high tensile strength, low elongation, strong tear resistance, minor differences in longitudinal and transverse strength, UV aging resistance, wear resistance, corrosion resistance, lightweight, and strong interlocking ability with soil or gravel, playing a significant role in enhancing soil shear resistance and reinforcing the overall integrity and load-bearing capacity of the soil.
4. Steel-plastic composite geogrid
Steel-plastic geogrid is made from high-strength steel wire, treated specially, and combined with PE, with other additives added, extruded into a composite high-strength anti-tensile strip, with a rough textured surface, forming a high-strength reinforcing geogrid. From this single strip, a certain spacing is created through longitudinal and transverse weaving or layering, using special reinforced adhesive welding technology to weld the joints, forming a reinforced geogrid.
Fiberglass Geogrid
5. Fiberglass geogrid is made from fiberglass using a certain weaving process to form a mesh structure material. To protect the fiberglass and improve overall performance, it is treated with a special coating process to create a highway reinforcement material.
Grass grid base construction
Many residential communities have green belts connecting the roads, with lawns generally paved to the roadside. Due to poor management, the soil in many green spaces becomes severely compacted. The emergence of grass grids solves this problem perfectly. Grass grids are also widely used in fire lanes and parking lots, addressing the issues of increasing green areas and improving the ecological environment and safety. Below are some analyses of grass grid construction and maintenance experiences for peer exchange and reference.
The main components of grass grid bases are as follows:
1. Raw soil compacting + gravel + gravel + grass grid + mixed nutrient soil
2. Raw soil compacting + gravel + concrete foundation + gravel + grass grid + mixed nutrient soil
3. Raw soil compacting + gravel + concrete foundation + gravel + non-woven fabric + grass grid + mixed nutrient soil
From the analysis of construction cases, we draw the following conclusions: The first solution allows for good drainage, but over time, due to surface load, the ground is prone to collapse; the second solution is susceptible to nutrient soil loss due to rainwater erosion over time. Through technical discussions and combining experiences with vertical greening, we advocate for the third solution, adding a non-woven fabric layer, which can prevent nutrient soil loss and also retain water.
1. Feature introduction: 1. Complete greening: Grass grids provide over 95% grassed area, achieving a full greening effect, capable of sound absorption and dust collection, significantly enhancing the quality and taste of the environment. (Reference: Concrete grass bricks only have 30% voids)
2. Cost-saving: Grass grids combine parking and greening functions; in land-scarce urban areas, they save valuable space for developers.
3. Flatness: The unique and stable flat interlocking design of grass grids creates a flat overall surface, avoiding local depressions and making construction extremely convenient. (Reference: Concrete grass bricks are independent, requiring a concrete base to maintain flatness)
4. High strength, long life: Grass grids use patented special materials, with a compression capacity of over 200 tons/square meter, greater than the standard requirement for fire-fighting access of 32 tons/square meter.
5. Stability: UV resistance, acid-base corrosion resistance, wear resistance, and weather resistance from -40℃ to 90℃. (Reference: Concrete grass bricks are prone to cracking and damage due to temperature changes and frost)
6. Excellent drainage: The gravel load-bearing layer provides good drainage, facilitating the discharge of excess precipitation.
7. Protecting lawns: The gravel load-bearing layer provides some water retention, beneficial for grass growth, allowing grass roots to grow into the gravel layer. (Reference: Concrete grass bricks only have very small spaces, and in summer, temperatures can exceed 50 degrees)
8. Green and environmentally friendly: Grass grids are safe, stable, recyclable, and pollution-free, fully protecting lawns.
9. Lightweight: Grass grids weigh only 5 kg per square meter, extremely lightweight, quick to install, saving labor and shortening construction time. (Reference: Concrete grass bricks weigh 250 kg per square meter)
2. Construction features: 1. Eco-friendly, non-toxic, pollution-free, impact-resistant, aging-resistant, UV-resistant
2. Wear-resistant, corrosion-resistant, flame-retardant, strong greening function
3. Reduces surface reflection, reduces surface heat radiation
4. Reduces sound wave transmission, lowers noise pollution
5. Reduces dust, purifies air
6. Rainwater naturally seeps, soil does not wash away, no pooling
7. Water, air, and fertilizer circulate naturally, soil does not compact
8. Increases greening area; simple construction, lightweight
9. Freely combinable and removable, reusable
10. Excellent load-bearing capacity: can withstand over 200T/square meter weight
3. Base treatment for parking area grass grids:
1. The foundation soil should be compacted in layers, achieving a compaction rate of over 85%; for soft plastic or fluid plastic silt layers, it is recommended to fill with block stones and compact to densify.
2. Set a 150 mm thick sand and stone cushion layer. The specific approach is: 10% coarse sand, 60% crushed stone with a particle size of 20-40, and 30% clay mixed evenly, leveled, and compacted.
3. Set a 60 mm thick stabilization layer (also serves as a planting layer). The stabilization layer should consist of 25% crushed stone with a particle size of 10-30, 15% medium coarse river sand, and 60% cultivated soil mixed with an appropriate amount of organic fertilizer, all thoroughly mixed, spread on the sand and stone cushion layer, and compacted to serve as the base for the grass grid.
4. Spread a small amount of organic fertilizer on the base layer, and manually lay the grass grids. The shape dimensions of the grass grids are designed according to the size modulus of the parking space, generally not requiring cutting; when the parking space has special shape requirements or sewage manhole covers are present, the grass grids can be cut to fit the different shape requirements of the parking space.
5. Spread planting soil in the recessed planting grooves of the grass grids and sweep evenly into the grid holes, with the soil layer height set to be 5-10 mm below the surface of the grass grid.
6. Lay sod or sow grass seeds on top of the planting soil layer. When laying sod, it should be pressed firmly onto the planting soil. Water and maintain until the grass takes root before allowing parking.
For grass grids used in fire lanes:
1. When laying grass grids on fire lanes, the compaction of the foundation soil should meet the design requirements for general concrete fire lanes.
2. The gravel cushion layer and stone powder stabilization layer for fire lanes should also meet the design requirements for ordinary concrete fire lanes.
3. On the stone powder stabilization layer, create an 80 mm thick planting soil layer. The soil layer should consist of 30% crushed stone with a particle size of 10-30, 15% medium coarse river sand, and 55% cultivated soil mixed with an appropriate amount of organic fertilizer, all thoroughly mixed, spread on the compacted stone powder stabilization layer, and compacted to serve as the base for the grass grid.
4. Install and plant grass grids on the grass grid base.
5. It is worth noting that if the fire lane serves as the main pathway for vehicles due to frequent use and high speed, this can adversely affect the use of grass grids and the normal growth of grass, thus impacting greening and aesthetics. In this case, we recommend that the main vehicle traffic roads continue to use concrete surfaces, while grass grids should only be used in emergency situations for fire vehicles. Similarly, it is advisable to use concrete surfaces for the main roadways in parking lots, while grass grids can be used for green parking spaces.
For sidewalks using grass grids:
1. The original foundation must be compacted.
2. Lay grass grids on the compacted soil surface.
3. Spread planting soil in the recessed planting grooves of the grass grids and sweep evenly into the grid holes, with the soil layer height set to be 5-10 mm below the surface of the grass grid.
4. Lay sod on top of the grass grid. When laying sod, it should be pressed firmly onto the planting soil. Water and maintain until the grass takes root before use.
4. Construction precautions: 1. The gravel foundation must be compacted, considering the significant bearing pressure, with a smooth surface and a drainage slope of 1%-2% preferred. Water drainage holes in concrete foundations must be filled with pebbles or gravel and sand to prevent soil loss.
2. Each grass grid has interlocking features; when installing, they should be locked together. Once installation is complete, use a small roller or plate vibrator to compact the surface of the grass grids, making adjustments as needed 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 allow the soil to settle, and a bamboo broom should be used to sweep the nutrient soil evenly into the grass grid holes, with the soil layer height set to be 5-10 mm below the surface of the grass grid.
4. The sod used is generally Manila grass, which is durable and easy to grow. When laying sod, leave about a 20 mm gap, staggering the layout in a checkerboard pattern. After laying the sod, water thoroughly to soften it, then use a small roller or plate vibrator to press the grass roots into the grass grids (repeating several times) to promote downward growth.
5. Allow a month of maintenance before parking; if installed between November and March of the following year (dormant period), the grass should be maintained for two months before parking.
6. During usage or after the rainy season, if a small amount of planting soil is lost, it can be evenly spread from the surface of the lawn to fill the soil washed away by rainwater.
7. The lawn requires 4-6 trims per year, timely weeding, fertilizing, and regular watering or installation of automatic sprinkler systems for necessary maintenance.
