Product Introduction:
I. Basic Attributes
Geo Fabric is a permeable geosynthetic material made primarily from polypropylene (PP) and polyester (PET) synthetic fibers through needle punching, weaving, or thermal bonding processes. It is mainly available in non-woven and woven structural types, with a complete range of specifications covering different weights, widths, and thicknesses. It boasts stable physical and mechanical properties, possessing not only excellent permeability and tensile strength, but also flexibility and superior chemical stability, making it suitable for various complex engineering foundation environments.
II. Core Functions
Geotextiles possess five core engineering functions: isolation, filtration, drainage, reinforcement, and protection. They effectively separate different soil layers and fillers, preventing mixing and maintaining structural stability; they achieve permeability while retaining fine particles, preventing piping and soil erosion; they can guide groundwater along the material plane, reducing pore water pressure and preventing soil softening or landslides; they can distribute loads, increasing the bearing capacity of foundations and slopes, and reducing settlement and deformation; and they can resist puncture, corrosion, and ultraviolet erosion, protecting underlying geomembranes and other engineering materials from damage.
III. Main Features
This product boasts high strength and toughness, is resistant to deformation, and is durable. It exhibits excellent resistance to acids and alkalis, corrosion, and UV aging, resulting in a long service life. Simultaneously, it is lightweight and flexible, facilitating cutting and laying without requiring specialized construction equipment. It can adapt to complex terrains, making construction convenient and efficient. The material is non-toxic, environmentally friendly, and pollution-free, making it suitable for ecological engineering construction and meeting the construction needs of various projects such as roads, water conservancy, slope protection, and landfills.

Product Applications:
Geotextiles are practical auxiliary materials in garden construction. They are easy to use and primarily function through four functions: isolation, filtration, drainage, and protection. They help solve common problems in planting flowers and grasses and creating landscapes, protecting plant growth, making gardens more durable, and reducing later maintenance.
Geotextiles used in gardens don't need to be high-strength; the key is lightweight and environmentally friendly, without harming plants or soil. They can separate different soil types and gravel, preventing soil compaction and protecting plant roots from damaging hard surfaces and waterproofing layers. They are also permeable to water and trap sediment, preventing drainage blockages and soil erosion, quickly draining excess water to prevent root rot in plants and cracking of hard surfaces due to water accumulation. They are also resistant to sun and rain, protecting the soil and waterproofing layers.
Geotextiles can be used in many places in gardens, such as flower beds, tree pits, and lawns. Laying geotextiles in flower beds can separate the planting soil from the underlying gravel, trap sediment, drain water, and improve the survival rate of plants. Choose non-woven geotextile; 150-250 g/m² is ideal. It's breathable, absorbent, soft, non-toxic, and environmentally friendly. Avoid using non-breathable woven geotextile. During construction, clean and level the bottom of the flower bed. If there's a gravel drainage layer, lay it down first, compact it, then lay the geotextile evenly, overlapping it 15-20 cm and securing it firmly. When filling with planting soil, avoid scratching or exposing the geotextile. For sunken flower beds, ensure proper drainage holes. When planting large plants, allow space for their roots.
Using geotextile in tree pits and tree arrays can solve problems such as tree roots damaging the structure, soil erosion, and waterlogging leading to root rot. For small tree pits, choose 150-200 g/m² non-woven geotextile; for large trees, choose 200-250 g/m², ensuring both strength and breathability. During construction, clean the bottom of the tree pit. If a drainage layer is available, first lay a 10-15 cm layer of crushed stone and compact it. Cover the bottom and walls of the pit with geotextile fabric, extending upwards and overlapping tightly. When filling with soil and planting the tree, cut the geotextile fabric around the tree roots. Do not lay too thick a layer later; cover any exposed areas with soil immediately.
Geo Fabric is a permeable geosynthetic material made of PP/PET synthetic fibers. It is divided into woven, non-woven, and composite types. Its core functions include isolation, filtration, drainage, reinforcement, seepage prevention, and protection. It is widely used in transportation, water conservancy, environmental protection, construction and municipal engineering, agriculture and aquaculture, and special engineering projects. In transportation engineering, it is used for roadbed reinforcement and pavement crack prevention, effectively reducing post-construction settlement and extending road life. In the field of water conservancy and flood control, it can realize dam slope protection and channel seepage prevention, resisting erosion and leakage. In the field of environmental protection and ecology, it can help prevent landfill seepage and restore wetlands, protecting the ecological environment. At the same time, in scenarios such as municipal construction, agricultural water conservation, and coastal land reclamation, it can also play a key role in preventing blockage, stabilizing structures, and reducing costs. Overall, it can significantly improve the stability of engineering structures, reduce later maintenance costs, and extend the service life of facilities, making it an indispensable and important material in modern infrastructure construction and ecological protection.
