Geotextiles have been used for thousands of years. These early geotextiles were made of natural fiber, fabrics or vegetation mixed with soil to improve road quality, particularly when roads were made on unstable soil. Then now, geotextile have used for modern construction. Although geotextiles have historically been made of natural plant, modern geotextiles are usually made from a synthetic polymer, such as polypropylene, polyester, polyethylene and polyamides.

Geotextile divided into three types, including woven, knitted or non-woven. Woven geotextile looks like burlap. It is a fabric made of two sets of parallel strands systematically interlaced to form a thin, flat fabric the strands are of two kinds - slit film which are flat, or monofilaments which are round. Non-woven geotextile is an arrangement of fibers either oriented or randomly pattern. These geotextiles provide planar water flow in addition to stabilization of soil. Typical applications include access roads, aggregate drains, asphalt pavement overlays, and erosion control.

Basically, geotextile can be used for erosion controller. It used blankets degraded which can produce an ineffectual installation. The synthetic polymers have the advantage of not decaying under biological and chemical processes, but being a petrochemical-based product they use non renewable resources in their construction, and cause environmental pollution in their manufacture use and have associated with your health risks.

Geotextile are only superior to hydro seeding and because of made in natural fiber such as coir, or jute can be used for wind erosion control, dust control, sand dune formation and stabilization. In another hand, synthetic geotextiles are uses in situations where hydro seeding would be a far more appropriate choice. Geotextile use will sometimes mask slope failures until erosion is too far advanced to effectively and cheaply remediate the slope.

In this modern time, the construction of roads, airfields, embankments, dams, canals and reservoirs used to geotextile fabrics. It has proved that they are really useful in its class, Geotextile. It has basically been used in all manner of different places and has proved itself to be extremely effective. If you are thinking about using it on your property then you can be sure that it has a very good track record.

Multi application can be used of geotextile fabrics; its material is also possible to do many other things. You will be able to plant things securely on steep slopes and increase on the strength of the soil. A similar type of fabric has even been for protecting fossilized footprints from the effects of rain, tree roots and erosion.

These materials are available in many different forms and they can be used for a number of different tasks. There is also a range that is specifically designed for use in the building industry. They are frequently used in the construction of roads and there are types that are created to help with drainage, reinforcement and the separation of different materials. Geotextile fabrics are, by no means, purely used as a simple ‘weed mat’ technique by gardeners.

This material not only superior strength and lower cost but also can separate the weak material with the good one. When considering what type of geotextile fabrics is use in a base stabilization application, consideration must be given to the products’ performance. Performance based designs allow the contractor to pick from a variety of solutions taking into account additional factors such as ease of installation, pricing and product availability.

Many modern structures now make very good use of these fabrics and when builders are laying a screed floor it is common practice to incorporate a geotextile material amongst the layers. In the United States they are now widely used in the construction of pavements as a filtering layer between the concrete surface of the pavement and its cement stabilized base. What is for sure is that the concept of geotextile products is changing the way that many things are being done; whether that is keeping weeds at bay, laying concrete floors or building new roads. It is really multi benefit and application of Geotextile fabrics.

China as we know is the country with millions of creativity. They cheat the other country’s product then make something innovation then the result is the new product succeeds to be produced. Like this matter, geotextile. Most of developing country hasn’t familiar yet with this technology, but China is in the first line to start produce this product. Geotextile is a woven or non woven permeable sheet and needle punch made from polypropylene and polyester. It reinforced stability structure for residential, industrial, urban, slope engineering, traffic engineering, waste landfill engineering, river/maritime engineering and other civil engineering.

In 2008, the Ministry of Transport is examining a plan to invest 5 trillion Yuan over the next 3-5 years. In the ten measures issued by the Council to stimulate domestic demands, an investment of 4 trillion Yuan was confirmed, most of it concentrated in infrastructure development. In the construction of projects for railways, roads, harbors and water conservancy projects, among others, geotextile will be totally used in this construction.

Having characteristic of High creep resistance, Simple construction equipments, Superior tensile reinforcement, Cost and time saving make China not think twice using it in case of China’s infrastructure. China also has anticipated heavy investment by the state government in railways and road construction will involve major development and utilization of geotextiles to solve application problems. Like nonwoven geosynthetics, geonets, geogrids, geomats, geocells and drainage boards. Let us show the result of establishment all china’s infrastructure which using geotextile technology.

Setelah itu, barulah dilakukan pengurugan dengan menggunakan bulldozer sampai padat berisi sesuai spesifikasi dari pihak pemberi tugas tersebut. Setelah urugan geotextile mencapai elevasi yang telah ditentukan, lembaran geotextile tersebut dilipat kemudian dijahit sehingga berbentuk bantalan. Setelah itu singkirkan bekisting yang kemudikan untuk dibuat pada bantalan selanjutnya. Dan hal ini dilakukan terus menerus sampai mencapai embankment yang ditentukan.

Geotextile, Geomembarane, dan Geogrid.

Kali ini kita akan membahas sedikit mengenai pemasangan HDPE dimana HDPE merupakan bahan dasar dari Geomembrane.

Pada pemasangan HDPE LINER pada awalnya sebaiknya harus mempersiapkan pola-pola atau layout untuk masing-msing saluran, angkur tepi dari liner, pertemuan pipa liner, serta struktur serta pipa linear secara detailnya dari konsultan atau owner yang bersangkutan, selain itu program kerja dan materi pendukung juga diikutsertakan sehingga perkiraan bisa lebih akurat lagi.

Selain itu persiapan kerja di lapangan juga dibutuhkan mulai dari pembentukan fisik dari saluran , sistem grading pada permukaan yang digali, pemadatan pada dasar saluran serta penyediaan pembangunan yang biasanya diberikan langsung oleh owner atau para pemberi kerja.

Setelah persiapan-persiapan tersebut barulah pekerjaan langsung dilakukan. Diawali dengan penyesuaian antara shop drawing dengan as built drawing, pemotongan lembaran liner, peletakan material liner di lapangan, penempelan lembaran liner, pembersihan daerah hubungan liner, pengelasan yang menggunakan extrude fusion system dan hot wedge system, hingga tahap uji coba yang dilakukan oleh pengawas lapangan sebagai antisipasi agar tidak ada kebocoran, dan apabila itu terjadi dapat diperbaiki dengan dilas memakai alat  extruder dan material welding rod. Serta tak lupa mempersiapkan laporan/pencatatan dalam proses pemasangan.

Untuk mengetahui lebih jelas mengenai apa itu Geotextile berikut ini adalah kutipan penjelasan dari wikipedia

Geotextile adalah sejenis kain yang, ketika digunakan dalam hubungannya dengan tanah, memiliki kemampuan untuk memisahkan, menyaring, memperkuat, melindungi, atau saluran pembuangan. Biasanya terbuat dari polypropylene atau polyester, kain Geotextile datang dalam tiga bentuk dasar: tenun (seperti tas surat pemecatan), jarum menekan (seperti merasa), atau panas Berikat (seperti menyetrika merasa).

Geotextile komposit telah diperkenalkan dan produk-produk seperti geogrids dan jerat telah dikembangkan. Secara keseluruhan, materi ini disebut sebagai Geosynthetics dan setiap konfigurasi - geonets, geogrids dan lain-lain - dapat menghasilkan keuntungan dalam rekayasa geoteknik dan lingkungan desain.
