Rough geomembrane
Rough geomembrane is generally made of high-density polyethylene (HDPE) or polypropylene as raw materials, and is refined by professional production equipment and special production processes, with a rough texture or bumps on the surface.

Anti-seepage geotextile
Anti-seepage geotextile is a special geosynthetic material used to prevent water penetration. The following will discuss its material composition, working principle, characteristics and application fields.

Concrete drainage board
Concrete drainage board is a plate-shaped material with drainage function, which is made by mixing cement as the main cementitious material with stone, sand, water and other admixtures in a certain proportion, followed by processes such as pouring, vibration and curing.
-
Reinforced geomembrane
Reinforced geomembrane is a composite geotechnical material made by adding reinforcing materials into the geomembrane through specific processes based on the geomembrane. It aims to improve the mechanical properties of the geomembrane and make it better adapt to various engineering environments.

Plastic drainage net
Plastic drainage net is a kind of geosynthetic material, usually composed of a plastic core board and a non – woven geotextile filter membrane wrapped around it.

Non – woven weed – control fabric
Non – woven grass – preventing fabric is a geosynthetic material made of polyester staple fibers through processes such as opening, carding, and needling. It is honey – comb – like and comes in the form of a fabric. The following is an introduction to its characteristics and applications

Sheet drainage board
Sheet drainage board is a type of drainage board. It is usually in the shape of a square or rectangle with relatively small dimensions, such as the common specifications of 500mm×500mm, 300mm×300mm or 333mm×333mm. It is made of plastic materials such as polystyrene (HIPS), polyethylene (HDPE) and polyvinyl chloride (PVC). Through the injection molding process, shapes such as conical protrusions, stiffening rib bumps or hollow cylindrical porous structures are formed on the plastic bottom plate, and a layer of filter geotextile is glued on the top surface.
-
Self-adhesive drainage board
The self-adhesive drainage board is a drainage material made by compounding a self-adhesive layer on the surface of an ordinary drainage board through a special process. It combines the drainage function of the drainage board with the bonding function of the self-adhesive glue, integrating multiple functions such as drainage, waterproofing, root separation and protection.

Glass fiber geogrid
Glass fiber geogrid is a kind of geogrid formed by using alkali – free and untwisted glass fiber roving as the main raw material. It is first made into a net – structured material through a special weaving process, and then undergoes surface coating treatment. Glass fiber features high strength, high modulus, and low elongation, providing a good foundation for the mechanical properties of the geogrid.
-
Steel-plastic geogrid
The steel – plastic geogrid takes high – strength steel wires (or other fibers) as the core stress – bearing framework. After special treatment, it is combined with plastics such as polyethylene (PE) or polypropylene (PP) and other additives, and a composite high – strength tensile strip is formed through the extrusion process. The surface of the strip usually has rough embossed patterns. Each single strip is then woven or clamped longitudinally and transversely at a certain spacing, and the joints are welded by a special strengthened bonding and fusion welding technology to finally form the steel – plastic geogrid. -
Biaxially – Stretched Plastic Geogrid
It is a new – type geosynthetic material. It uses high – molecular polymers such as polypropylene (PP) or polyethylene (PE) as raw materials. The plates are first formed through plasticizing and extrusion, then punched, and finally stretched longitudinally and transversely. During the manufacturing process, the high – molecular chains of the polymer are re – arranged and oriented as the material is heated and stretched. This strengthens the connection between the molecular chains and thus increases its strength. The elongation rate is only 10% – 15% of that of the original plate.
-
Plastic Geogrid
- It is mainly made of high – molecular polymer materials such as polypropylene (PP) or polyethylene (PE). Visually, it has a grid – like structure. This grid structure is formed through specific manufacturing processes. Generally, the polymer raw material is first made into a plate, and then through processes such as punching and stretching, a geogrid with a regular grid is finally formed. The shape of the grid can be square, rectangular, diamond – shaped, etc. The size of the grid and the thickness of the geogrid vary according to specific engineering requirements and manufacturing standards.
