Biaxial Stretching Geogrid is a high-strength reinforced geosynthetic material made from polypropylene (PP) as raw material, produced through plastic extrusion, sheet punching, longitudinal stretching, and transverse stretching. It has many advantages such as high strength, structural stability, anti-aging, and corrosion resistance. Application Field: Biaxial Stretching Geogrids are mainly used for reinforcement in soft soil engineering such as highways and railways, as well as slope protection and large landfill projects. They can greatly enhance the bearing capacity of soft soil foundations, prevent surface cracks and collapses, facilitate construction, and reduce maintenance costs. Biaxial plastic geogrid models include: Fiberglass geogrid strength (30kn-120kn), polyester geogrid strength (30kn-300kn), steel-plastic geogrid model (30-150kn), biaxial plastic geogrid strength (15kn-50kn), uniaxial plastic geogrid strength (35kn-300kn). Geogrid widths: The maximum width of fiberglass geogrid, steel-plastic geogrid, polyester geogrid, and biaxial plastic geogrid is 6 meters. The roll length of fiberglass geogrid is 100 meters, steel-plastic geogrid is 50 meters, polyester geogrid is 100 meters. The roll lengths of biaxial plastic geogrids are 100 meters and 50 meters. The width of uniaxial plastic geogrids is 3 meters, with a roll length of 50 meters. Xiamen Geogrid Co., Ltd - Welcome 15269874999 Biaxial Plastic Geogrid 1. Biaxial Plastic Geogrid Uniaxial stretching geogrid is a high-strength geosynthetic material made from high polymer materials as the main raw material, with certain UV-resistant and anti-aging agents added. After uniaxial stretching, the originally scattered chain-like molecules are reoriented into a linear state, extruded into thin plates, and then punched into a regular mesh, and subsequently longitudinally stretched. This process aligns the polymers into a directional linear state and forms a uniformly distributed, high-strength node structure. This structure has a high tensile strength and modulus, with a tensile strength of 100-200 MPa, close to the level of low carbon steel, greatly exceeding traditional or existing reinforcement materials, especially as these products exhibit internationally superior early (elongation rate of 2%-5%) tensile strength and modulus. It provides an ideal force-bearing and diffusion chain system for the soil. The product has high tensile strength (>150 MPa) and is suitable for various soils, making it a widely used reinforcement material. Its main features include: high tensile strength, good creep performance, easy construction, and low cost. Uniaxial geogrid is made from high polymer materials (PP or HDPE), extruded into thin sheets, punched into regular meshes, and then longitudinally stretched. This process aligns the polymers into a directional linear state and forms a uniformly distributed, high-strength node structure. Main Uses: 1. Uniaxial geogrids are used for reinforcing weak foundations: Geogrids can rapidly increase the bearing capacity of the foundation, control the development of settlement, and effectively distribute loads over a wider subgrade, thereby reducing subgrade thickness, lowering project costs, shortening construction periods, and extending service life. 2. Uniaxial geogrids are 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 also reduce asphalt or cement layer thickness to save costs. 3. Uniaxial geogrids are used for reinforcing embankments and retaining walls: Traditional embankments, especially high embankments, often require overfilling, and the shoulder edges are difficult to compact, leading to post-construction slope erosion and collapse. Uniaxial geogrids can reinforce embankment slopes or retaining walls, reducing land use by 20-50%, extending service life, and lowering costs. 4. Uniaxial geogrids are used for reinforcing river and sea dikes: They can be made into stone cages and used with geogrids to prevent dikes from being eroded by seawater, causing collapse. Stone cages have permeability, mitigating wave impacts, extending dike life, and saving labor and resources while shortening construction periods. 5. Uniaxial geogrids are used for landfill management: When used with other geosynthetic materials, geogrids can effectively address uneven settlement and gas emission issues, significantly improving the storage capacity of landfills. 6. Special applications of uniaxial geogrids: Low-temperature resistance. After 200 cycles of freezing and thawing 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 poor geological conditions with high ice content. Construction Methods: ○ When used for subgrade and pavement, the construction methods are the same as for biaxial geogrids. ○ When used for reinforced soil retaining walls, the construction method is as follows: 1. Set up the foundation according to the designed wall system. When using prefabricated reinforced concrete panels, they generally have a thickness of 12-15 cm and are supported on prefabricated concrete foundations. Their width should not exceed 30 cm, thickness not less than 20 cm, and buried depth not less than 60 cm to prevent foundation frost heave effects. 2. Level the wall foundation according to design requirements, excavating and leveling as needed. Soft soil must be compacted or replaced, compacted to the required density slightly exceeding the wall surface area. 3. Lay the reinforcement material, ensuring the main strength direction is perpendicular to the wall surface, secured with pins. 4. Fill the wall with soil using mechanical filling, maintaining a distance of at least 15 cm between the wheels and the reinforcement material. After compaction, each layer of soil should be approximately 20-15 cm thick. 5. During wall construction, the wall surface should be wrapped in geotextile to prevent soil loss. Biaxial geogrids are made from polyethylene or polypropylene through extrusion, forming sheets, and then longitudinal and transverse stretching. Welded plastic geogrids: Biaxial welded geogrids are a new environmentally friendly building material, reinforced with fibers in polyethylene or polypropylene stretching strips, then welded into a "#" structure. They can be divided into single and double-sided adhesive or welded geogrids. This product has high strength, low deformation, corrosion resistance, long life, and easy and quick construction, with low costs. They are positioned flat, especially meeting the requirements for use in various long-term projects of over 100 years. 2. Uniaxial Plastic Geogrid: Uniaxial plastic geogrid is made from polyethylene, extruded into thin sheets, then punched into a regular mesh, and longitudinally stretched. This process aligns the polymers into a directional linear state and forms a uniformly distributed, high-strength node structure. Uses: ● River dikes, lake dams, tailings dams, wastewater dams, reservoirs, channels, and liquid storage pits (pits, ponds). ● Subway, basement, and tunnel seepage-proof linings. ● Saline seepage prevention for subgrades and other foundations; geogrid model specifications. ● Horizontal seepage-proof covering before dikes and dams, vertical seepage layers for foundations, construction cofferdams, waste sites. ● Saltwater and freshwater aquaculture. ● Subgrades for highways, expressways, and railways; waterproof layers for expansive clay and collapsible loess. ● Roof seepage prevention. 3. Warp-knitted Polyester Geogrid: Warp-knitted polyester geogrid is made from high-strength polyester fibers. It uses a warp-knitted directional structure, where the warp and weft yarns are in a straight state without bending, and the intersections are bound together with high-strength fiber filaments, forming strong binding points, fully utilizing its mechanical properties. High-strength polyester warp-knitted geogrid has high tensile strength, low elongation, high tear strength, small longitudinal and transverse strength differences, UV resistance, wear resistance, corrosion resistance, lightweight, and strong locking force with soil or gravel, significantly enhancing soil shear resistance and improving overall integrity and load-bearing capacity. 4. Steel-Plastic Composite Geogrid: Steel-plastic geogrid is made from high-strength steel wire, treated specially, and combined with PE, with additional agents added, extruded into a composite high-strength tension strip. The surface has rough textures, which are high-strength reinforced strip materials. A single strip is woven or arranged at certain intervals in both longitudinal and transverse directions, using special reinforced bonding and welding technology at the joints to form a reinforced geogrid. 5. Fiberglass Geogrid: Fiberglass geogrid is made from glass fiber, using a specific weaving process to create a mesh structure. To protect the glass fiber and enhance overall performance, it undergoes a special coating treatment process, making it a road reinforcement material. Grass Grid Base Construction: Many residential communities have roads adjacent to green belts, with lawns generally extending to the roadside. The soil in many green spaces becomes compacted due to lack of management. The emergence of grass grids solves this issue and is also widely used in fire lanes and parking lots. It addresses the problem of increasing green space and improving ecological environment and safety. Below is an analysis of the construction and maintenance experiences of grass grids for reference and communication among peers. Grass grid base construction can be accomplished using the following schemes: 1. Plain soil compaction + gravel + crushed stone + gravel + grass grid + mixed nutrient soil. 2. Plain soil compaction + crushed stone + concrete foundation + gravel + grass grid + mixed nutrient soil. 3. Plain soil compaction + crushed stone + concrete foundation + gravel + non-woven fabric + grass grid + mixed nutrient soil. From the analysis of construction cases, we conclude that the first scheme facilitates drainage but may lead to surface collapse over time due to load. The second scheme may cause nutrient loss due to rainwater erosion, leading to a decrease in nutrient soil within the grass grid. Based on technical discussions and experiences in vertical greening, we advocate for the third scheme, which adds a non-woven fabric layer to prevent nutrient soil loss and retain moisture. 1. Characteristics Introduction 1. Complete Greening: Grass grids provide over 95% greening area, achieving a full greening effect, capable of sound absorption and dust control, significantly enhancing environmental quality and aesthetics. (Reference: Concrete grass bricks only have 30% voids) 2. Savings: Grass grids combine parking and greening functions, saving precious space for developers in densely populated urban areas. 3. Smooth and Complete: The unique and stable flat interlocking of grass grids creates a smooth overall surface, avoiding local depressions, making construction extremely convenient. (Reference: Concrete grass bricks are independent, requiring a concrete base layer to maintain flatness) 4. High Strength, Long Life: Grass grids use patented special materials, with a compressive capacity of 200 tons/square meter, exceeding the regulatory requirement of 32 tons/square meter for fire emergency access. 5. Stable Performance: UV resistance, acid and alkali corrosion resistance, wear resistance, and weather resistance from -40℃ to 90℃. (Reference: Concrete grass bricks can easily crack and break under temperature changes and frost) 6. Excellent Drainage: The gravel load-bearing layer provides good drainage capabilities, facilitating the discharge of excess rainfall. 7. Protecting Lawns: The gravel load-bearing layer offers some water retention capacity, which benefits grass growth, allowing grass roots to extend into the gravel layer. (Reference: Concrete grass bricks provide minimal space, with temperatures exceeding 50 degrees Celsius in summer) 8. Eco-Friendly: Grass grids are safe, stable, recyclable, and pollution-free, fully protecting lawns. 9. Lightweight and Cost-Effective: Grass grids weigh 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) 2. Building Characteristics 1.

Freely combinable and detachable; can be reused. 10. Excellent load-bearing capacity: can withstand over 200T/square meter. 3. Base Treatment Base treatment for grass grids used in parking spaces: 1. The foundation soil should be compacted in layers, with a compactness of over 85%; for soft plastic or flowable mud layers, it is recommended to lay block stones and compact them until firm. 2. Set a 150 mm thick sand and stone cushion layer. The specific method is to mix 10% medium sand, 60% 20-40 particle size gravel, and 30% clay soil, compacting them into a dense layer. 3. Set a 60 mm thick stabilization layer (also serving as a planting layer). The stabilization layer consists of 25% 10-30 particle size gravel, 15% medium-sized river sand, and 60% cultivated soil mixed with organic fertilizer; all three should be evenly mixed and spread over the sand and stone cushion layer, compacted until firm, serving as the base for the grass grid. 4. Sprinkle a little organic fertilizer on the base layer and manually lay the grass grids. The dimensions of the grass grids are designed based on parking space dimensions, generally not requiring cutting; when there are special shapes or manhole covers on the parking spaces, the grass grids can be cut to fit the different shapes required. 5. Spread planting soil in the recessed planting slots of the grass grids and evenly sweep it into the grid holes, ensuring the soil layer height is 5-10mm below the surface of the grass grids. 6. Lay sod or sow grass seeds on the planting soil layer. When laying sod, it must be pressed firmly onto the planting soil. Water and maintain until the grass takes root, after which parking can begin. Base treatment for grass grids used in fire lanes: 1. When laying grass grids on fire lanes, the foundation soil's compactness should meet the design requirements of standard concrete fire lanes. 2. The gravel cushion and stone powder stabilization layer methods should also comply with standard concrete fire lane design requirements. 3. A 80 mm thick planting soil layer should be made on the stone powder stabilization layer. The soil layer consists of 30% 10-30 particle size gravel, 15% medium-sized river sand, and 55% cultivated soil mixed with organic fertilizer; all three should be evenly mixed and spread over the compacted stone powder stabilization layer, compacted until firm, serving as the base for the grass grid. 4. Grass grids should be installed and planted on the base layer. 5. It is worth noting that if the fire lane serves as a primary traffic route for vehicles, frequent and fast-moving traffic may adversely affect the use of grass grids and the normal growth of grass, thus affecting greening and aesthetics. In this case, we recommend using concrete surfaces for main vehicle traffic routes, while grass grids can be used for surfaces that only emergency vehicles may access. Similarly, for parking lots, the main access routes are better suited for concrete surfaces, while parking spaces can utilize grass grids for greening. Base treatment for grass grids used in walkways: 1. The original foundation must be compacted. 2. Install grass grids on the compacted base soil. 3. Spread planting soil in the recessed slots of the grass grids and evenly sweep it into the grid holes, ensuring the soil layer height is 5-10mm below the surface of the grass grids. 4. Lay sod on the grass grids. When laying sod, it must be pressed firmly onto the planting soil. Water and maintain until the grass takes root, after which it can be used. 4. Construction Precautions: 1. The gravel foundation must be compacted thoroughly, with surface level maintained, ideally having a drainage slope of 1%-2%. Drainage holes in the concrete foundation must be filled with pebbles or gravel and sand to prevent soil loss. 2. Each grass grid is interlinked; during installation, they must be interlocked. After completing the grass grid installation, use a small roller or plate vibrator to compress the surface of the grass grids. Any uneven areas should be adjusted until the surface of the grass grids is level. 3. It is recommended to use nutritious soil to fill the grass grids. When backfilling, water should be applied to allow the soil to settle. Use a broom to evenly sweep the nutritious soil into the holes of the grass grids, ensuring the soil layer height is 5-10mm below the surface of the grass grids. 4. Sod is generally made from Manila grass, which is durable and easy to grow. When laying sod, leave about a 20mm gap and stagger the installation in a herringbone pattern. After laying the sod, water it thoroughly to soften it, then use a small roller or plate vibrator to press the grass roots into the grass grids (repeating this multiple times) to facilitate downward growth. 5. Maintenance should be performed for one month before parking; if the grass is installed between November and March of the following year (dormant period), it should be maintained for two months before parking. 6. During usage or after rainy seasons, if some planting soil is lost, sprinkle a little soil or sand from the surface of the lawn to refill the washed-out soil. 7. The lawn requires trimming 4-6 times a year, timely weeding, fertilizing, and regular watering, especially during hot and dry seasons, or installing automatic watering systems for necessary maintenance.
