GEOSYNTHETICS
Geosynthetics are the generally polymeric products used to solve
civil engineering problems. This includes eight main product
categories: geotextiles, geogrids, geonets, geomembranes, geosynthetic
clay liners, geofoam, geocells and geocomposites.
The polymeric nature of the products makes them suitable for
use in the ground where high levels of durability are required. Properly
formulated, however, they can also be used in exposed applications.
Geosynthetics are available in a wide range of forms and materials,
each to suit a slightly different end use.
These products have a wide range of applications and are
currently used in many civil, geotechnical, transportation,
geoenvironmental, hydraulic, and private development applications
including roads, airfields, railroads, embankments, retaining structures,
reservoirs, canals, dams, erosion control, sediment control, landfill
liners, landfill covers, mining, aquaculture and agriculture.

Nonwoven Geotextiles form one of the two largest groups of geosynthetics. Their rise in
growth during the past years has been nothing short of extraordinary.
Nonwoven geotextiles have a wide range of applications in civil environmental
engineering and construction projects. Their uses include:
Filtration of soils in drainage applications by retaining soil particles while allowing for
the free flow of water.
Separation and stabilization in road and railway construction.
Prevention of soil movement in erosion control measures.
Cushioning and protection in many containment projects.
Produced from high quality Polyester and polypropylene fibres,
Nonwoven
Geotextiles are needle punched to form a strong fabric that retains its dimensional stability
and is resistant to damage from construction stresses.
Nonwoven Geotextiles are available in varying strengths and thicknesses to
ensure appropriate material selection for your project. This product has to span the mass
start 150 gram/m2 up to 600 gram/m2. While wide up to 2.0 meters can be produced
though generally produced is 6.0 meters (roll width) to optimally the transportation
volume by using container

Woven Geotextiles form one of the two largest groups of geosynthetics. Their rise in
growth during the past years has been nothing short of extraordinary.
woven geotextiles are often used for separation and stabilization in the
construction of roads. The woven geotextile’s separation action prevents the mixing of
dissimilar soils allowing each soil layer in the road structure to function as intended. The
high tensile strength and low elongation properties of woven geotextiles impart stability
into the road section reducing rutting and extending roadway life.
Woven geotextiles are also used in filtering and reinforcement applications.
woven geotextiles are woven from durable, high-modulus polypropylene yarns
into competent, robust, dimensionally stable geotextiles. Woven geotextiles are available
in varying tensile strengths and hydraulic properties to suit particular project demands.
Application
Woven have the very low prolong level for the application of hoard and land strength
which is very important for those application, and also made as international standard.
Geotextile with the high strength is suitable either for the application of strength for hoard
and soft land because can prevent the transfer of hoard material and also strengthen the
guardian coat as well.
The high strength only used high quality polypropylene in production to get the lower
prolongs level, whereas it’s very important for the application of strength. The Long-term
creep of Fiber used in course of production has been tested base on international standard.

INTRODUCTION
is Geogrids represent a rapidly growing segment within geosynthetics. Geogrids
are polymers formed into a very open, is manufactured from Polypropylene (PP) or High
Density Polyethylene (HDPE), grid like configuration, i.e., they have large apertures
between individual ribs in the transverse and longitudinal directions.
Geogrids are either stretched in one or two directions for improved physical properties,
made on weaving or knitting machinery by standard manufacturing methods, or by
bonding rods or straps together.
There are many specific application areas, however, they function almost exclusively as
reinforcement materials.
The latest development in stiff polymer geogrid manufacture is based on an isosceles
triangular aperture, produced by a new manufacturing technique from a punched then
stretched polymer sheet.
Uniaxial Geogrids are polymers formed into a very open, is manufactured from
Polypropylene (PP) or High Density Polyethylene (HDPE).
It is produced through the process of extruding, punching, heating and stretching. With
Performance High Tensile Strength, High elastic modulus and Low Creep Deformation.
Application:
• Soft foundation reinforcing for highway
• Reinforcing for retaining wall, deck and steep slope.
• Mainly used in the highway, railway, retaining wall, dam and steep slope
Benefits:
• Improving bearing capacity of foundation, retaining wall and dam
• Extending the project life
• Reducing floor area
• Shortening contructions period, reducing cost and maintaining expense

PERFORATED DRAIAGE PIPE
When the rain pours and flooding occurs, perforated pipe is a good solution. Coming in a variety of sizes for an
equally diverse number of uses, this perforated pipe helps ease soggy yards, flooded fields and wet basements.
Knowing the different options is a great way to understand what the best type of drainage is for a particular
situation.
Perforated pipe can be made of a variety of materials, including iron, PVC, cement and clay, but the most
popular type is polyethylene. This thick polyethylene is lightweight and flexible. Flexibility is essential for these
types of pipes, because they are always buried underground. When the ground expands and contracts with the
seasons, more rigid pipes can crack, but polyethylene flexes with the movement and stays in one piece.
The signature characteristic of perforated pipe is the perforated holes or slots in the pipe. By cutting holes or
slots, it can fill with water when the ground becomes saturated. This pipe carries the wetness away and allows the
ground to stay dry. The number and size of holes differ between pipes because each combination serves different
purposes. Most are relatively small in order to keep dirt out of the tube and prevent buildup and clogging.

BRONJONG/GABIONS
Gabions are manufactured with all components mechanically connected at the production facility to manufacture
high-quality wire, as per ASTM A975-97 and ISO-03-0090-1999. All gabions are given in the form of collapse,
either folded or rolled and bundled. Files are compressed and bonded together at the factory for easy shipping
and handling. Lacing wire shipped in rolls. Fasteners are shipped in boxes. Preformed stiffeners shipped in
bundles. Made from a thick galvanized mild steel wire, woven through supervision and meticulous process in
accordance with the standard.

PP GEOTUBE
INTRODUCTION
1.
Raw Material: PP Geotube are sewn Polypropelen (PP) woven long fiber geotextile.
2.
Benefits: Relatively low cost, defense to seasonal erosion, easily removed.
3.
Applications: Geotube are used to from shoreline structure including form temporary breakwaters, headlands,
revetments on sand beaches of seashore.
4.
Installation for PP Geotube:
a. Filling sand or sludge into PP Geotube: Need higher pressure water syringe and mud pump. Firstly, start the water
syringe to blow up the sand or sludge into the mud pump, then push into geotube by mud pump.
b. Water drainage: PP geotube is made of PP long fiber geotextile by woven. Many small hole in the geotextile, so the
water can be drained from the sludge, sand, other solid material, but the solid material can be trapped in the
geotube. The geotube can be filled and drained several times. Usually, the solid material up to 70% of total geotube
volume is enough.
c. Concretion:
d. After several times of filling and drainage, the sand, sludge and other solid material inside geotube is concreted
slowly by degrees because of desiccation.

PREFABRICATED VERTICAL DRAIN (PVD)
Informasi Singkat PVD
PVD telah digunakan di berbagai proyek di seluruh dunia yang melibatkan reklamasi lahan, pekerjaan
infrastruktur, bangunan industri dan pengembangan real estat.
Instalasi PVD adalah biaya-efektif solusi pengobatan tanah yang sangat untuk mengkonsolidasikan tanah jenuh
air dan meningkatkan stabilitas tanah. Pre-loading dapat dipersingkat dan berkurang, sehingga biaya proyek yang
lebih rendah dan waktu yang lebih singkat konsolidasi sebelum pekerjaan konstruksi dapat dimulai. Biaya
pemeliharaan masa depan juga lebih rendah karena berkurangnya penyelesaian sisa. Instalasi PVD juga
merupakan metode yang efektif untuk mengurangi hipertensi tanah dekat lereng dan biaya tambahan, sehingga
mengurangi risiko kegagalan lereng.
