PP Woven Geotextile PET
PP woven geotextile Introduction
Our supplied PP woven geotextile is plastic woven film yarn geotextile, created on large industrial looms that interlace horizontal and vertical threads to form a tight criss-cross or mesh. The flat threads are made by pp resin extrusion, splitting, stretching processing ways.
Woven geotextile fabrics tend to be lightweight and much stronger than nonwoven geotextile because of processing way difference. Woven geotextile fabrics tend to be used for construction projects that will be long-lasting. Its performance can meet or exceed our national standard GB/T17690.

Staple Fiber PET Nonwoven geotextile Introduction
Staple fiber PET nonwoven geotextile is permeable fabric which has the ability to separate, filter, reinforce, protect, or drain.
It is made from 100% polyester(PET) staple fiber without chemical additives and heating. It is needle punched by our advanced equipment, which of the main equipment is imported from Germany.
PET material itself has a good UV and chemical resistance properties. It is an environmental friendly construction material.
Staple fiber PP geotextile has the main functions of separation, filtration, drainage and reinforcement.

PP Biaxial Geogrid
We, PT Metro Rekayasa Indonesia, is a HDPE biaxial geogrid and other geosynthetics supplier in Indonesia. The soil body strength and deformation characteristics can be enhanced and improved after the reinforcement materials are mixed or laid. Geogrid is a quite important part of the reinforcement material family. HDPE biaxial geogrid can be defined as plastic stretching geogrid, which can be classified from woven PET geogrid, woven glass fiber geogrid, and others.
HDPE Biaxial Geogrid Introduction
HDPE biaxial geogrid is made of polymer material of high density polyethylene. It is extruded into sheet and then punched into regular mesh pattern, then stretched into a grid in longitudinal and transverse directions.
The high polymer of plastic geogrid is directionally arranged in the heating and stretching process of manufacturing, which strengthen the binding force between molecular chains so it increases the grid strength.
The principal function of HDPE biaxial geogrid is for reinforcement.
The key feature of geogrid is that the openings between the adjacent sets of longitudinal and transverse ribs, called “apertures,” are large enough to allow for soil strike-through from one side of the geogrid to the other. The reason for this is that in anchorage situations the soil strike-through within the apertures bears against the transverse ribs, which transmits the load to the longitudinal ribs via the junctions. The junctions are, of course, where the longitudinal and transverse ribs meet and are connected.
1. Stabilizes the retaining walls, subbases, subsoils below roads or structures.
2. Provides excellent stress transfer.
3. Prevents deterioration/shifting of base material.
4. Increases structure life span.
5. Chemical, UV, and biological resistance.
