Geotextile Material

A geotextile is defined as any permeable textile material that is used with foundation, soil, rock, earth which increase stability and decrease wind and water erosion. A geotextile may be made of synthetic or natural fibers. In contrast, a geomembrane is a continuous membrane-type liner or barrier geomembrane must have sufficiently low permeability to control migration of fluid in a constructed project, structure or system. A geotextile is designed to be permeable to allow the flow of fluids through whereas a geomembrane is designed to restrict the fluid flow.

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.

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.

Geotextile yang digunakan dalam Embankment memiliki prosedur pelaksanaan tersendiri ,  prosedur awal haruslah menyiapkan lahan, bekisting dan geotextile. Yang lebih diperhatikan disini adalah, alangkah lebih baik bila menyingkirkan benda-benda tajam yang kemungkinan dapat menusuk geotextile itu sendiri. Lalu geotextile tersebut dipotong-potong menurut ukuran yang telah ditentukan, potongan tersebut seperti lembaran yang setelah itu dijahit melintang. Lalu antara lembaran-lembaran tersebut digabungkan sesuai kapasitas pengurugan dan juga siapkan sisanya untuk penambungan panel berikutnya. (more…)

Geosynthetics terdiri dari berbagai macam diantaranya adalah :

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.

Saat ini geotextile telah banyak digunakan dalam berbagai proyek baik proyek pemerintah maupun proyek swasta. Proyek yang saat ini banyak menggunakan geotextile ada proyek-proyek seperti transportation engineering, marine & hydraulics engineering dan lain sebagainya.

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).
