A geocell is a three-dimensional honeycomb structure made of high-molecular-weight polymers (most commonly HDPE) connected by high-strength welds. Its unique structure enables it to provide integral reinforcement within the confines of soil, gravel, concrete, and other fillers. As such, geocells play a vital role in a variety of civil engineering applications, including roads, slope protection, water conservancy projects, railways, and landfills.

Geogrids offer excellent reinforcement. Their grid-like structure effectively interlocks with soil or other fillers, significantly increasing the soil's tensile strength and overall stability. This reinforcement not only reduces foundation settlement but also increases the bearing capacity of projects such as roads, railways, water conservancy projects, and dams, making them safer and more reliable.

Geotextiles offer multiple functions, including isolation, reinforcement, filtration, drainage, and protection. They effectively prevent soil mixing, improve foundation bearing capacity, and extend the life of projects. In road and railway construction, geotextiles enhance roadbed stability; in water conservancy and environmental protection projects, they are used for anti-seepage, drainage, and slope protection, such as in embankments, river channels, and landfills; and in landscape and architectural projects, they provide both permeability and protection.

A geocell is a three-dimensional honeycomb grid structure made of polymers (primarily high-density polyethylene (HDPE), polypropylene (PP), or reinforced polyester) connected by ultrasonic or thermal welding. Its shape resembles a honeycomb, forming regular polygonal units when unfolded. To use, the cells need to be opened and filled with soil, sand, gravel, or concrete to form a composite reinforcement with overall stability.

A geotube, also known as a geotube or geotextile tube, is a tubular structure made primarily of high-strength geotextile fabric. It is used for solid-liquid separation, drainage, and soil reinforcement. It typically takes the form of a long strip or tube and can be filled with slurry, soil, or other granular materials. Combining the high strength, permeability, and durability of geotextile fabric, a geotube can withstand high filling pressures while allowing liquid to drain, thereby consolidating solid particles and reinforcing the soil.

Gabions are cage-like structures made of metal mesh (commonly galvanized steel, galvanized wire, or PVC-coated steel) woven or welded into cage-like units, filled with inert materials such as stones and pebbles. Gabions can be used individually or connected to form a complete slope protection, wall, or bank protection system.

Glass fiber geogrid is a new type of geosynthetic material with high strength and low elongation. Its unique grid structure and excellent compatibility with asphalt materials can form a "skeleton" in asphalt pavements, effectively inhibiting crack propagation. Its multiple functions include stress diffusion, displacement restraint, and crack isolation, demonstrating excellent performance in resolving reflective cracks.

As a classic geotechnical reinforcement material, biaxial geogrid has become an important choice in engineering fields such as roads, railways, water conservancy, and municipal engineering due to its excellent tensile strength, structural stability and wide range of applications.

Polyester geogrids can disperse loads, reinforce soil, and prevent deformation, greatly improving the stability and durability of the project. With high strength and low creep, they provide efficient, economical, and reliable solutions for soft soil foundation settlement and slope collapse risks.

The Three-dimensional Vegetation Net uses a three-dimensional mesh structure to secure soil and grass seeds on the slope, preventing rainwater from washing away the soil while providing a good environment for plant growth. As grass roots gradually intertwine with the net, a composite protective system of "plants + soil + net" forms on the slope.

Prefabricated Vertical Drain (PVD), also known as Band Drain or Plastic Drain Board (PDB), is becoming an indispensable new material for soft soil foundation treatment. It is a long, strip-shaped drainage structure composed of a filter membrane, core board, and cladding. During construction, it is inserted into the soil using a specialized inserter. Combined with surcharge preloading or vacuum preloading, it significantly shortens the consolidation time of soft soil foundations, accelerates pore water drainage, and significantly improves the bearing capacity and stability of the foundation.

Composite geomembrane, a new type of anti-seepage material, is gaining widespread application. Composed of an anti-seepage geomembrane and geotextile, either thermally or adhesively bonded, it combines the high anti-seepage capabilities of a membrane with the strength, ductility, and damage resistance of a geotextile, making it a key material of choice for current anti-seepage projects.
