1. Bidirectional Plastic Geogrid
Unidirectional Stretch Geogrid is a high-strength geosynthetic material made from polymer as the main raw material, adding certain UV-resistant and aging-resistant additives, and through unidirectional stretching, the originally scattered chain molecules are reoriented in a linear state, extruded into thin sheets, and then punctured into regular mesh. Then it is longitudinally stretched to form a high-strength geosynthetic material. This process makes the polymer in a directional linear state, forming a uniformly distributed, high node strength, long oval network structure. This structure has a very high tensile strength and tensile modulus, with tensile strength reaching 100-200Mpa, close to the level of low carbon steel, greatly exceeding traditional or existing reinforcement materials. Especially, this product has exceptional early (elongation rate of 2%-5%) tensile strength and tensile modulus at an international level. It provides an ideal force-bearing and diffusion link system for the soil. The product has large tensile strength (>150Mpa), suitable for various soils, and is currently widely used as a reinforcement material. Its main characteristics are: high tensile strength, good creep performance, easy construction, and low cost.
Unidirectional Geogrid is made from polymer (PP or HDPE) extruded into thin sheets, then punched into a regular mesh, and then longitudinally stretched. This process makes the polymer in a directional linear state, forming a uniformly distributed, high node strength, long oval network 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 foundation bearing capacity, control the development of settlement, and effectively distribute loads to a wider sub-base, thereby reducing sub-base 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 pavement fatigue life, and can also reduce asphalt or cement layer thickness to save costs.
3. Unidirectional Geogrid is used for reinforcing embankments and retaining walls: Traditional embankments, especially high embankments, often require overfilling, and the edges are difficult to compact, leading to post-construction slope erosion, collapse, and instability. At the same time, it requires a gentler slope, occupying a large area. Retaining walls also have similar problems. Using geogrids to reinforce embankment slopes or retaining walls can reduce the area occupied by half, extend service life, and lower costs by 20-50%.
4. Unidirectional Geogrid is used for reinforcing river and sea dikes: It can be made into stone cages and used together with geogrids to prevent dikes from being washed away by seawater, causing collapse. Stone cages have permeability, which can mitigate wave impact, extend dike life, save manpower and resources, and shorten construction time.
5. Unidirectional Geogrid is used for dealing with landfill sites: Geogrids used with other geosynthetic materials can effectively solve problems such as uneven foundation settlement and gas emissions, and can greatly enhance the storage capacity of landfills.
6. Special uses of Unidirectional Geogrids: Low-temperature resistance. After 200 cycles of repeated heating and cooling at -45℃ to -50℃, all performance indicators meet the requirements and have been tested on the Qinghai-Tibet Railway, suitable for poor geology in northern regions with little frozen soil, rich frost soil, and high ice content.
Construction methods
○ When used for subgrade and pavement, the construction method is the same as that of bidirectional geogrids.
○ When used for reinforced soil retaining walls, the construction method is as follows:
1. Set the foundation according to the design of the wall system. When using precast reinforced concrete panels, the thickness is generally 12-15㎝ supported on precast concrete foundations. The width should not exceed 30㎝ and the thickness should not be less than 20㎝, with a burial depth of not less than 60㎝ to prevent foundation frost heave.
2. Level the wall base according to design requirements. Soft soil needs to be compacted or replaced, compacted to the required density, and should slightly exceed the wall range.
3. Lay the geogrid, with the main strength direction of the geogrid perpendicular to the wall, fixed with pins.
4. Fill the wall with soil, using mechanical filling, keeping a distance of at least 15㎝ between the wheels and the geogrid. After compaction, the thickness of each layer of soil is about 20-15㎝.
5. During wall construction, the wall surface should be wrapped with geotextiles to prevent soil loss.
Bidirectional Geogrid is made from polyethylene or polypropylene through extrusion, panel formation, and punching processes, followed by longitudinal and transverse stretching.
Welded Plastic Geogrid
Bidirectional welded geogrid is a new type of environmentally friendly building material, reinforced with reinforcing fibers in polyethylene or polypropylene stretch strips, and then welded into a “#” structure, which can be divided into single and double-sided adhesive and welded geogrids. This product has advantages such as high strength, low deformation, corrosion resistance, long life, quick and convenient construction, and low cost, providing a smooth and flat surface, especially meeting the requirements for use in various projects for over 100 years.
2. Unidirectional Plastic Geogrid
Unidirectional plastic geogrid is made from polyethylene extruded into thin sheets, then punched into a regular mesh, and subsequently longitudinally stretched. This process makes the polymer in a directional linear state, forming a uniformly distributed, high node strength, long oval network structure.
Uses:
● River embankments, lake dikes, tailings dams, sewage dams, reservoir areas, channels, and liquid storage pools (pits, trenches)
● Subway, basement, and tunnel waterproof linings.
● Subgrade and other foundation salinity waterproofing. Geogrid model specifications

3. Knitted Polyester Geogrid
Knitted polyester grids use high-strength polyester fiber as raw material. Using a knitted directional structure, the warp and weft yarns in the fabric are in a straight state, with the intersection points bound together by high-strength filaments, forming a strong bond point, fully utilizing their mechanical properties. High-strength polyester knitted geogrids have high tensile strength, low elongation, strong tear strength, small strength differences in the longitudinal and transverse directions, UV aging resistance, wear resistance, corrosion resistance, lightweight, and strong interlocking ability with soil or gravel, significantly 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 from high-strength steel wire, treated specially, combined with PE and other additives, extruded into a composite high-strength anti-tensile strip, and the surface has a rough embossed pattern, forming a high-strength reinforcing geogrid. Through a certain spacing, longitudinal and transverse arrangement, the welding of the joints using special reinforced adhesive welding technology forms the reinforcing geogrid.
Fiberglass Geogrid
5. Fiberglass Geogrid
Fiberglass geogrid is made from fiberglass material, produced through a specific weaving process to create a mesh structure. To protect the fiberglass and enhance overall performance, it undergoes special coating treatment, making it a road reinforcement material.
Grass Grid Base Composition
Many residential areas have roadways next to greening belts, with lawns generally laid up to the roadside. Many green land soils have become severely compacted due to insufficient management. The emergence of grass grids effectively solves this problem. Moreover, grass grids are widely used in fire lanes and parking lots, addressing the issue of increasing green space and enhancing safety. The following analyzes the construction and maintenance experiences of grass grids for reference and communication among peers.
The base composition of grass grids mainly includes the following schemes:
1. Natural soil compaction + crushed stones + natural soil + grass grid + mixed nutrient soil
2. Natural soil compaction + crushed stones + concrete foundation + natural soil + grass grid + mixed nutrient soil
3. Natural soil compaction + crushed stones + concrete foundation + natural soil + non-woven fabric + grass grid + mixed nutrient soil
From the analysis of construction cases, we draw the following conclusions: The first scheme allows for good drainage but may lead to surface collapse over time due to the load; the second scheme may cause nutrient soil loss due to heavy rainfall, leading to reduced nutrient soil levels within the grass grid; after technical discussions and combining experience in vertical greening, we advocate the third scheme, adding a non-woven fabric layer, which prevents nutrient soil loss and retains water.
1. Features introduction: 1. Complete greening: Grass grids provide over 95% greening area, achieving complete greening effects, which can absorb sound and dust, significantly enhancing environmental quality and taste. (Reference: Concrete grass bricks have only 30% voids)
2. Savings: Grass grids combine parking and greening functions, saving valuable space for developers in urban areas.
3. Flat and complete: The unique and stable flat interlocking of grass grids makes the entire laying surface a flat whole, avoiding local depressions, and construction is extremely convenient. (Reference: Concrete grass bricks are independent and must be laid on a concrete base to maintain flatness)
4. High strength, long life: Grass grids use patented special materials, with a compressive strength of up to 200 tons/square meter, exceeding the fire access surface requirement of 32 tons/square meter.
5. Performance stability, UV resistance, acid-alkali corrosion resistance, wear resistance, and weather resistance from -40℃ to 90℃. (Reference: Concrete grass bricks are prone to cracking and damage with temperature fluctuations and frost)
6. Excellent drainage: The crushed stone bearing layer provides good drainage functionality, facilitating the discharge of excess rainfall.
7. Protecting the lawn: The crushed stone bearing layer provides certain water retention capabilities, benefiting lawn growth, allowing grass roots to extend into the crushed stone layer. (Reference: Concrete grass bricks have very little space, with temperatures exceeding 50 degrees in summer)
8. Green and environmentally friendly: Grass grids are safe and stable, recyclable, and fully pollution-free, providing comprehensive care for lawns.
9. Lightweight and economical: Grass grids weigh only 5 kg per square meter, extremely lightweight, quick to install, saving labor and shortening construction cycles. (Reference: Concrete grass bricks weigh 250 kg per square meter)
2. Building characteristics: 1. Environmentally friendly, non-toxic, pollution-free, impact-resistant, aging-resistant, UV-resistant.
2. Wear-resistant, corrosion-resistant, good flame-retardant properties, strong grass-planting functionality.
3. Reduces ground reflection, reduces ground thermal radiation.
4. Reduces ground sound wave transmission, lowering noise pollution.
5. Reduces dust, purifies air.
6. Rainwater naturally seeps, soil does not lose, and there is no water accumulation phenomenon.
7. Water, air, and fertilizer naturally circulate, and soil layers do not compact.
8. Increases greening area · Simple construction, lightweight.
9. Can be freely combined and disassembled, reusable.
10. Good load-bearing effects: can withstand over 200T/square meter weight.
3. Base treatment for parking space grass grids:
1. The base soil should be compacted layer by layer, with a compactness of over 85%; for soft plastic-flowing silt layers, it is recommended to fill with block stones and compact them to density.
2. Set a 150 thick sand and stone cushion layer. Specific methods are: 10% medium coarse sand, 60% crushed stone with a particle size of 20-40, and 30% clay mixed evenly, spread flat and compacted to density.
3. Set a 60 thick stable layer (also serves as a planting layer). The stable layer consists of 25% crushed stone with a particle size of 10-30, 15% medium-fine river sand, 60% cultivated soil, and an appropriate amount of organic fertilizer mixed evenly, spread on the sand and stone cushion layer, and compacted to density, which can serve as the base for grass grids.
4. Sprinkle a little organic fertilizer on the base, manually lay the grass grids. The shape dimensions of the grass grids are designed based on the parking space size modulus, generally not requiring cutting; if the parking space has special shape requirements or has a sewage manhole cover, the grass grids can be cut to fit different shapes of the parking space.
5. Sprinkle planting soil in the recessed planting slots of the grass grids and evenly sweep into the holes of the grass grids with a broom, with a soil layer height below the grass grid surface by 5-10mm as a standard.
6. Lay sod or sow grass seeds on top of the planting soil layer of the grass grids. When laying sod, it should be compacted onto the planting soil. Water and maintain until the grass takes root, then parking can commence.
For grass grids used in fire lanes:
1. When laying grass grids on fire lanes, the compactness of the base soil should meet the design requirements for general concrete fire lanes.
2. The crushed stone cushion layer and stone powder stable layer of fire lanes should also meet the design requirements for ordinary concrete fire lanes.
3. On top of the stone powder stable layer, create an 80 thick planting soil layer. The soil layer consists of 30% crushed stone with a particle size of 10-30, 15% medium-fine river sand, 55% cultivated soil, and an appropriate amount of organic fertilizer mixed evenly, spread on the compacted stone powder stable layer and compacted to density, which can serve as the base for grass grids.
4. Lay grass grids and sow grass on the grass grid base.
5. It is worth noting that if the fire lane serves as a main passage for regular vehicles, frequent and fast vehicle movement may be detrimental to the use of grass grids and normal grass growth, thus affecting greening rates and aesthetics. In this case, we recommend that major vehicle traffic roads still use concrete pavement, while grass grids should be used only in emergency situations for fire vehicles to enter. Similarly, we suggest using concrete pavement for the main access roads of parking lots, while grass grids can be used for parking spaces.
For grass grids used in pedestrian pathways:
1. The original base should be compacted.
2. Lay grass grids on the compacted base surface.
3. Sprinkle planting soil in the recessed planting slots of the grass grids and evenly sweep into the holes of the grass grids with a broom, with a soil layer height below the grass grid surface by 5-10mm as a standard.
4. Lay sod on the grass grids. When laying sod, it should be compacted onto the planting soil. Water and maintain until the grass takes root, then it can be used.
4. Construction precautions:
1. The crushed stone base requires compaction, considering significant bearing pressure, with a flat surface and a drainage slope of 1%-2% being optimal. Water permeation holes in concrete foundations must be filled with pebbles or crushed stones and sand to prevent soil loss.
2. Each grass grid has interlocking rings, ensuring they fit together during installation. After laying the grass grids, use a small roller or plate vibration machine to press the surface back and forth once. Any uneven areas should be adjusted until the surface of the grass grids is level.
3. The soil filled within the grass grids is recommended to be nutrient soil. When backfilling, it should be watered to allow the soil to settle. Use a broom to evenly sweep the nutrient soil on the surface into the holes of the grass grids, with a soil layer height below the grass grid surface by 5-10mm as a standard.
4. Grass is generally of the Manila variety, which is foot-tread resistant and easy to grow. When laying sod, leave about a 20mm gap, and stagger the layout. After the sod is laid, thoroughly water it to soften, then use a small roller or plate vibration machine to press the grass roots into the grass grids (repeatedly), allowing the grass roots to grow downward.
5. Maintenance is required for one month before parking can commence; if the grass is planted between November and March of the following year (dormant period), it should be maintained for two months before parking.
6. If there is a slight loss of planting soil during use or after the rainy season, a small amount of soil or sand can be evenly sprinkled on the lawn surface to fill in the soil lost due to rainwater erosion.
7. The lawn requires 4-6 trims a year, timely weeding, fertilizing, and during hot and dry seasons, regular watering or installation of automatic sprinkling devices is necessary for proper maintenance management.
