The price of geogrids mainly depends on the choice of raw materials; generally, geogrids have a service life of over twenty years. Due to users' lack of understanding of the products, it is easy to fall into the price trap, thinking that the lower the price, the better. Often, they ignore product quality, leading to losses during use. Misconceptions when purchasing fiberglass geogrids: 1. Selection misconception: Geogrids are not just about being affordable; as a kind of corrosion-resistant material, different models of geogrids have different qualities and should be selected based on the specific usage environment and construction requirements. It is advisable to communicate with manufacturers and make careful choices. 2. Price misconception: When purchasing items, we often think the lower the price, the better the deal, but little do we know that we end up harming ourselves, as the items purchased cannot be used.

Bidirectional stretched geogrids are high-strength reinforced geosynthetic materials made from polypropylene (PP) through plastic extrusion, sheet punching, longitudinal stretching, and transverse stretching. They have high strength, structural stability, anti-aging, corrosion resistance, and many other advantages. Application fields: Bidirectional stretched geogrids are mainly used for reinforcing soft soil projects such as highways and railways, as well as slope protection and large landfill engineering, significantly enhancing the bearing capacity of soft soil foundations, preventing surface cracks and collapses, facilitating construction, and reducing maintenance costs. The models of bidirectional plastic geogrids include: fiberglass geogrids with strength (30kn-120kn), polyester geogrids with strength (30kn-300kn), steel-plastic geogrids with strength (30-150kn), bidirectional plastic geogrids with strength (15kn-50kn), and unidirectional plastic geogrids with strength (35kn-300kn).

Ningde, Geogrid Co., Ltd - Welcome 15269874999 Bidirectional Plastic Geogrid 1. Bidirectional Plastic Geogrid Unidirectional stretched geogrids are high-strength geosynthetic materials made from high polymer compounds, with added anti-ultraviolet and anti-aging additives. They undergo unidirectional stretching to realign the originally random chain-like molecules into a linear state, which are then extruded into thin sheets and punched into regular holes, followed by longitudinal stretching. This process aligns the polymers in a linear state and forms a uniformly distributed structure with high node strength. This structure possesses considerable tensile strength and tensile modulus, with a tensile strength reaching 100-200 MPa, approaching low carbon steel levels, significantly outperforming traditional or existing reinforcement materials. This type of product also exhibits internationally superior early (elongation rate of 2%-5%) tensile strength and tensile modulus, providing an ideal force-bearing and diffusion system for soil. The tensile strength of this product is high (>150MPa), making it suitable for various soils and currently widely used as a reinforcement material. Its main features include: high tensile strength, good creep performance, easy construction, and low cost. Unidirectional geogrids are made from high polymer materials (PP or HDPE) that are extruded into thin sheets and then punched into regular holes before undergoing longitudinal stretching. This process aligns the polymers in a linear state, forming a uniformly distributed structure with high node strength. Unidirectional stretched geogrids are a type of high-strength geosynthetic material. Main uses: 1. Unidirectional geogrids are used for reinforcing weak foundations: geogrids can quickly improve foundation bearing capacity and control settlement development. Their lateral confinement on road subbase can effectively distribute loads over a wider subbase, thereby reducing subbase thickness, lowering project costs, shortening construction time, and extending service life. 2. Unidirectional geogrids are used for reinforcing asphalt or cement pavements: geogrids laid at the bottom of asphalt or cement layers can reduce rutting depth, extend pavement fatigue life, and reduce asphalt or cement layer thickness to save costs. 3. Unidirectional geogrids are used for reinforcing embankments and retaining walls: traditional embankments, especially high embankments, often require overfilling, and the edges are difficult to compact, leading to problems such as slope erosion and instability during rain. Also, they require gentler slopes, occupying larger areas; retaining walls face similar issues. Using geogrids to reinforce embankment slopes or retaining walls can reduce land occupation by 20-50%, extend service life, and lower costs. 4. Unidirectional geogrids are used for reinforcing river and sea dikes: they can be made into stone cages combined with geogrids to prevent dikes from collapsing due to seawater erosion. Stone cages have permeability, which can mitigate wave impact and prolong dike lifespan, saving labor and materials and shortening construction time. 5. Unidirectional geogrids are used for landfill treatment: geogrids used in conjunction with other geosynthetic materials can effectively solve issues related to uneven foundation settlement and gas emissions, significantly improving landfill storage capacity. 6. Special uses of unidirectional geogrids: low-temperature resistance. After 200 cycles of repeated heating and cooling at -45°C to -50°C, all performance indicators meet requirements and have been tested in the Qinghai-Tibet Railway, suitable for northern regions with less frost, rich frost, and high ice content in poor geological conditions. Construction methods: ○ When used for subgrades and pavements, the construction method is similar to bidirectional geogrids. ○ When used for reinforced 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 should be generally 12-15 cm thick and supported on a prefabricated concrete foundation. The width should not exceed 30 cm, the thickness not less than 20 cm, and the embedment depth not less than 60 cm to prevent frost heave from affecting the foundation. 2. Level the wall base according to design requirements. Soft soil needs to be compacted or replaced, compacted to the required density, slightly exceeding the wall surface range. 3. Install the reinforcement along the main strength direction perpendicular to the wall, secured with pins. 4. Fill the wall with soil using machinery, maintaining a distance of at least 15 cm between the wheel and the reinforcement. After compaction, the thickness of each layer of soil should be about 20-15 cm. 5. During wall construction, the wall surface should be covered with geotextile to prevent soil loss. Bidirectional geogrids are made from polyethylene or polypropylene through extrusion, sheet formation, and punching, followed by longitudinal and transverse stretching. Welded plastic geogrids: Bidirectional welded geogrids are a new type of environmentally friendly building material that incorporates reinforcing fibers into polyethylene and polypropylene stretch bands, forming a "#" structure, which can be categorized into single or double-sided adhesive or welded geogrids. This product features high strength, low deformation, corrosion resistance, long lifespan, easy and quick construction, and low cost, providing a level surface that meets various long-term engineering requirements of over 100 years. 2. Unidirectional plastic geogrids: Unidirectional plastic geogrids are made from polyethylene extruded into thin sheets, then punched into regular holes and longitudinally stretched. This process aligns the polymers in a linear state, forming a uniformly distributed structure with high node strength. Uses: ● Dikes, lake dams, tailings dams, sewage dams, reservoirs, channels, and liquid storage pits (pits, ponds). ● Subway, basements, tunnels, and underground seepage-proof linings. ● Foundation and other saline seepage prevention layers; geogrid specifications. ● Horizontal seepage-proof coverings before dikes and dams, vertical seepage-proof layers for foundations, construction cofferdams, and waste sites. ● Saltwater and freshwater aquaculture. ● Subgrades for highways, expressways, and railways; waterproof layers for expansive soil and collapsible loess. ● Roof seepage-proofing. 3. Warp-knitted polyester geogrids: Warp-knitted polyester geogrids utilize high-strength polyester fibers as raw materials. They are made using warp-knitted structures, with no bending states between the warp and weft yarns, and the intersection points are bound together with high-strength fiber filaments, forming sturdy bonding points that fully utilize their mechanical properties. High-strength polyester warp-knitted geogrids have high tensile strength, low elongation, high tear strength, minimal strength differences in both directions, UV aging resistance, abrasion resistance, corrosion resistance, lightweight, and strong interlocking with soil or gravel, significantly enhancing soil shear resistance and improving the integrity and load-bearing capacity of the soil. 4. Steel-plastic composite geogrids: Steel-plastic geogrids are made of high-strength steel wires that are specially treated and combined with PE and other additives to form a composite high-strength anti-tensile strip through extrusion. The surface has rough textures, making it a high-strength reinforced geosynthetic material. This single strip is then woven or arranged at specified intervals and welded at the junctions using special reinforcement bonding techniques, forming the reinforced geogrid. 5. Fiberglass geogrids: Fiberglass geogrids are made from fiberglass and constructed using a specific weaving process to form a mesh structure. To protect the fiberglass and enhance overall performance, they undergo a special coating treatment, making them suitable for road reinforcement materials. Grass grid sub-base composition: Many residential areas have roads adjacent to green belts, where the lawn typically extends to the roadside. However, due to poor management, the soil in many green areas becomes severely compacted. The introduction of grass grids effectively addresses this issue. They are also widely used in fire lanes and parking lots, solving the problem of increased green space and enhancing ecological safety. Below is an analysis of the grass grid construction and maintenance experience for peer reference. The main sub-base compositions for grass grids include the following options: 1. Solid soil compaction + gravel + crushed stone + gravel + grass grid + mixed nutrient soil. 2. Solid soil compaction + gravel + concrete base + gravel + grass grid + mixed nutrient soil. 3. Solid soil compaction + gravel + concrete base + gravel + non-woven fabric + grass grid + mixed nutrient soil. Through analysis of construction cases, we draw the following conclusions: The first option provides smooth drainage, but over time, due to surface load, the ground is prone to collapse; the second option, over time, results in rainwater washing away nutrients, causing nutrient loss in the soil within the grass grid. After technical discussions combined with experiences in vertical greening, we recommend the third option to increase the non-woven fabric layer, which can prevent nutrient loss and help retain water. 1. Feature introduction: 1. Complete greening: The grass grid provides over 95% grass coverage, achieving a complete greening effect, which can absorb sound and dust, significantly enhancing environmental quality and aesthetics. (Reference: Concrete grass bricks have only 30% voids.) 2. Savings: Grass grids combine parking and greening functions, saving valuable space for developers in densely populated urban areas. 3. Even and complete: The unique and sturdy interlocking design of grass grids creates a flat surface, avoiding localized depressions, and making construction extremely convenient. (Reference: Concrete grass bricks are independent and require a concrete base to maintain levelness.) 4. High strength, long lifespan: Grass grids are made from patented special materials with a compressive strength of up to 200 tons/square meter, exceeding the 32 tons/square meter requirement for fire lane surfaces. 5. Stability of performance: UV resistance, acid-base corrosion resistance, abrasion resistance, and weather resistance from -40°C to 90°C. (Reference: Concrete grass bricks can easily crack and break under temperature changes and frost.) 6. Excellent drainage: The gravel bearing layer provides good drainage capabilities, facilitating the discharge of excess precipitation. 7. Protecting lawns: The gravel bearing layer allows for some water retention, benefiting lawn growth, and allowing grass roots to extend into the gravel layer. (Reference: Concrete grass bricks have very little space, and temperatures can exceed 50 degrees Celsius in summer.) 8. Eco-friendly: Grass grids are safe, stable, recyclable, and pollution-free, fully protecting grass lawns. 9. Lightweight and cost-effective: Grass grids weigh only 5 kg per square meter, making them extremely lightweight, easy to install, saving labor costs, and shortening construction time. (Reference: Concrete grass bricks weigh 250 kg per square meter.) 2. Construction characteristics: 1. Environmentally friendly, non-toxic, and pollution-free; impact-resistant, aging-resistant, and UV-resistant. 2. Wear-resistant, corrosion-resistant, and flame-retardant; strong grass growth capability. 3. Reduces surface reflection and heat radiation. 4. Reduces surface sound wave transmission and lowers noise pollution. 5. Reduces dust and purifies the air. 6. Rainwater naturally infiltrates without soil loss or water accumulation. 7. Water, air, and nutrients circulate naturally, preventing soil compaction. 8. Increases green coverage; construction is simple and lightweight. 9. Can be freely combined and disassembled, reusable. 10. Excellent load-bearing capacity: can withstand weights over 200T/square meter. 3. Foundation treatment for parking space grass grids: 1. The subgrade soil should be compacted in layers, achieving a compaction degree of over 85%; for soft plastic or flowable mud layers, it is recommended to fill with block stones and compact them firmly. 2. A 150mm thick sand and stone cushion layer should be set. The specific method is: 10% medium coarse sand, 60% gravel with 20-40mm particle size, and 30% clay mixed evenly, spread and compacted to a dense state. 3. A 60mm thick stabilization layer (also serving as a planting layer) should be set. The stabilization layer consists of 25% gravel with 10-30mm particle size, 15% medium coarse river sand, and 60% cultivated soil mixed with appropriate amounts of organic fertilizer, evenly blended, spread over the sand and stone cushion layer, and compacted to serve as the grass grid sub-base. 4. A small amount of organic fertilizer should be spread over the sub-base before manually laying the grass grid. The dimensions of the grass grid are designed according to the dimensions of the parking space, generally not requiring cutting; if there are special shape requirements or sewage manholes in the parking area, the grass grid can be cut to fit different shapes. 5. Planting soil should be spread in the planting slots of the grass grid and evenly swept into the holes, with the soil layer height set to 5-10mm below the grass grid surface. 6. Grass sod or seeds should be laid on the planting soil layer. When laying sod, it should be pressed firmly onto the planting soil. Water should be applied for maintenance, and once the grass is established, parking can commence. For fire lane grass grids: 1. Grass grids should be laid on fire lanes, and the subgrade soil's compaction should meet the design requirements for general concrete fire lanes. 2. The gravel cushion layer and stone powder stabilization layer should also follow the design requirements for ordinary concrete fire lanes. 3. An 80mm thick planting soil layer should be established on top of the stone powder stabilization layer. The soil layer consists of 30% gravel with 10-30mm particle size, 15% medium coarse river sand, and 55% cultivated soil mixed with appropriate amounts of organic fertilizer, evenly blended, spread on the compacted stone powder stabilization layer, and compacted to serve as the grass grid sub-base. 4. Grass grids should be laid and planted on the grass grid sub-base. 5. Note: If the fire lane serves as the main passage for vehicles due to frequent traffic and high speeds, this could adversely affect the use of grass grids and the normal growth of grass, thereby impacting greening rates and aesthetics. In such cases, we recommend using concrete pavement for major traffic routes but using grass grids only for emergency access during firefighting. Similarly, for main traffic roads in parking lots, concrete pavement is advised, while grass grids can be used for green parking spaces. For pedestrian walkways with grass grids: 1. The original foundation should be compacted. 2. Grass grids should be laid on the compacted base soil surface. 3. Planting soil should be spread in the planting slots of the grass grid and evenly swept into the holes, with the soil layer height set to 5-10mm below the grass grid surface. 4. Grass sod should be laid on the grass grid. When laying sod, it should be pressed firmly onto the planting soil. Water should be applied for maintenance, and once the grass is established, the walkway can be used. 4. Construction precautions: 1. The gravel base must be compacted, considering the substantial bearing pressure. The surface should be flat, with a drainage slope of 1%-2% being optimal. Water drainage holes in the concrete foundation must be filled with pebbles or gravel and sand to prevent soil loss. 2. Each grass grid has interlocking links, and they should be interlocked during installation. After laying the grass grids, a small roller or plate vibrator should be used to compress the surface, making adjustments as necessary 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 sprinkled to allow the soil to settle. A bamboo broom should be used to evenly sweep the nutrient soil into the grass grid holes, setting the soil layer height to 5-10mm below the grass grid surface. 4. The sod is generally Manila grass, which is foot-tolerant and easy to grow. When laying sod, about 20mm gaps should be left, and the sod should be staggered in a cross pattern. After laying the sod, water it thoroughly until it is soft, then use a small roller or plate vibrator to compact the grass roots into the grass grid (repeatedly), allowing the grass roots to grow downwards. 5. Maintenance should be conducted for one month before parking; 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 some planting soil is lost during use or after the rainy season, a small amount of soil or sand can be evenly sprinkled over the surface of the lawn to fill in the soil lost due to rainwater washing. 7. The lawn should be trimmed 4-6 times a year, weeds should be removed promptly, and fertilizing should be done. In hot and dry seasons, regular watering or the installation of automatic irrigation systems is essential for proper maintenance management.
