HDPE geocell (High-Density Polyethylene Geocell) "honeycomb structure" has received widespread attention and application. As a three-dimensional cell-shaped product made of high-density polyethylene as the main raw material, formed by extrusion and ultrasonic welding, it not only has high tensile strength and good flexibility, but also can be stretched and unfolded on site to form a stable spatial grid system. After filling with various granular materials, it can build a reinforced composite with a strong structure and strong adaptability.

The anti-seepage system is an important part of ensuring the safety and environmental performance of the structure. Among the many anti-seepage materials, GCL (bentonite waterproof blanket) and geomembrane are the two most widely used.

Geogrids are roughly divided into two categories: uniaxial geogrid and biaxial geogrid. The two have their own characteristics in manufacturing methods, force directions, reinforcement effects and application scenarios. Reasonable selection directly affects the quality and economy of the project.

Polyester geogrid is a geosynthetic material made of high-strength polyester filaments woven into a mesh structure and treated with PVC coating. It is mainly used to strengthen the soil structure, improve its overall stability and bearing capacity, and has been widely used in infrastructure construction, road engineering, railways, bridges, slope reinforcement and other fields.

Non-woven geotextile is a flexible and permeable geosynthetic material made of short fiber or filament material (such as polypropylene, polyester) through needle punching, hot rolling or hydroentanglement. It is different from woven geotextile (with obvious warp and weft texture), but presents a fiber structure with no direction arrangement, which makes it have strong physical properties in multiple directions.

As a key waterproof and anti-seepage material, geomembrane plays an irreplaceable role. Its performance is not only related to the type of material (such as HDPE, LLDPE, etc.), but also closely related to its thickness selection. Geomembranes of different thicknesses have significant differences in tensile strength, puncture resistance, flexibility and service life.

In order to prevent the leachate from polluting the groundwater and surrounding ecological environment, building an efficient and reliable anti-seepage system has become a basic requirement for modern garbage disposal. It has become the core material in the anti-seepage project of landfills.

"Geomembrane" and "composite geomembrane" are the two most common types. They are widely used in landfills, water conservancy projects, mine heap leaching tanks, transportation projects, artificial lakes and other fields.

As a polymer anti-seepage material, geomembrane is widely used in anti-seepage systems such as landfills, artificial lakes, reservoirs, tailings dams, tunnel waterproofing, and heap leaching tanks. In these applications, one link plays a decisive role, which is the welding quality of geomembrane.

GCL (bentonite composite waterproof cushion) is being widely used in various projects such as landfills, reservoirs, subway tunnels, etc. due to its excellent anti-seepage performance, simple construction and economy.

Plastic Grass Grid, also known as "grass grid", "greening grid" and "ecological grass floor", is a honeycomb modular ground paving material made of high-density polyethylene (HDPE) or polypropylene (PP) through injection molding. It takes into account both bearing capacity and greening function, can effectively protect the roots of the lawn and prevent soil compaction, and has good drainage performance and ecological permeability.

Woven geotextile is a flat geosynthetic material made of high-strength synthetic fibers (such as polypropylene PP or polyester PET) arranged crosswise by weaving. Its typical structure is that the longitudinal and transverse fibers are regularly crossed to form a grid-like fabric surface, which has good mechanical properties and stability.
