GeosyntheticsGeosynthetics are synthetic products used to stabilize terrain, contain liquids, drain liquids, and filter particles. They are 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.
Geotextile tubeA geotextile tube is a large, tube-shaped bag made of porous, weather-resistant geotextile and filled with a sand slurry, to form an artificial coastal structure such as a breakwaters, dune or levee. Geotextile tubes are a component of the living shorelines approach to coastal management. They are aligned with the shoreline to weaken wave energy and protect against coastal erosion.
Geosynthetic clay linerGeosynthetic clay liners (GCLs) are factory manufactured hydraulic barriers consisting of a layer of bentonite or other very low-permeability material supported by geotextiles and/or geomembranes, mechanically held together by needling, stitching, or chemical adhesives.
GeogridA geogrid is geosynthetic material used to reinforce soils and similar materials. Soils pull apart under tension. Compared to soil, geogrids are strong in tension. This fact allows them to transfer forces to a larger area of soil than would otherwise be the case. Geogrids are commonly made of polymer materials, such as polyester, polyvinyl alcohol, polyethylene or polypropylene.
Geotechnical engineeringGeotechnical engineering, also known as geotechnics, is the branch of civil engineering concerned with the engineering behavior of earth materials. It uses the principles of soil mechanics and rock mechanics to solve its engineering problems. It also relies on knowledge of geology, hydrology, geophysics, and other related sciences.
GeonetsA geonet is a geosynthetic material similar in structure to a geogrid, consisting of integrally connected parallel sets of ribs overlying similar sets at various angles for in-plane drainage of liquids or gases. Geonets are often laminated with geotextiles on one or both surfaces and are then referred to as drainage geocomposites. They are competitive with other drainage geocomposites having different core configurations.
Environmental engineeringEnvironmental engineering is a professional engineeringdiscipline related to environmental science. It encompasses broad scientific topics like chemistry, biology, ecology, geology, hydraulics, hydrology, microbiology, and mathematics to create solutions that will protect and also improve the health of living organisms and improve the quality of the environment. Environmental engineering is a sub-discipline of civil engineering and chemical engineering.
SoilEarth, a natural materialSurface-water-gley developed in glacial till in Northern IrelandSoil, also commonly referred to as earth, is a mixture of organic matter, minerals, gases, water, and organisms that together support the life of plants and soil organisms. Some scientific definitions distinguish dirt from soil by restricting the former term specifically to displaced soil.
PolyesterPolyester is a category of polymers that contain one or two ester linkages in every repeat unit of their main chain. As a specific material, it most commonly refers to a type called polyethylene terephthalate (PET). Polyesters include some natural products, such as those found in plants and insects. Natural polyesters and a few synthetic ones are biodegradable, but most commercial polyesters are not. Polyesters are used extensively in clothing.
PolypropylenePolypropylene (PP), also known as polypropene, is a thermoplasticpolymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomerpropylene. Polypropylene belongs to the group of polyolefins and is partially crystalline and non-polar. Its properties are similar to polyethylene, but it is slightly harder and more heat-resistant. It is a white, mechanically rugged material and has a high chemical resistance.
TextileVarious fibre-based materialsLongitudinal yarns (warp) are interlaced with weft or filing yarns to create a woven fabricHandmade floral patterns on textiles Weaving demonstration on an 1830 handloom in the weaving museum in LeidenA textile is any of various fibre-based materials, including fibres, yarns, filaments, threads, and different types of fabric.
Woven fabricWoven fabric is any textile formed by weaving. Woven fabrics, often created on a loom, are made of many threads woven in a warp and weft. Technically, a woven fabric is any fabric made by interlacing two or more threads at right angles to one another. Woven fabrics can be made of natural fibers, synthetic fibers, or a mixture of both, such as cotton and polyester. Woven fabrics are used for clothing, garments, decorations, furniture, flags, carpets and other uses.*As an Amazon Associate I earn from qualifying purchases.
