PARKSIDE-BSS has strategically aligned itself in a business development sense , for the marketing and sales of products from some of the leading global manufacturers of Geosynthetics. HDPE Pipes, Agri Film and Roll Form Concrete so that it is able to provide the best product supply service, with the best products at the most competitive rates.
“GEOSYNTHETIC” refers to a product that is made from polymeric material and is applied as a key component in a structure or system to achieve engineering purposes.
The prefix “geo” suggests whose application is linked with use in soil, rock, and/or the earth.
There are some important basic functions of Geosynthetics namely separation, reinforcement, filtration, drainage, containment, barrier, surface erosion control, and protection.
Any geosynthetic product is expected to provide one or more of these functions.
The use of Geosynthetics in Construction, Mining, Infrastructure, Agriculture and other major Industries has now reached the point of almost universal acceptance, where many projects these products on a first choice basis.
There are several product categories of Geosynthetics, but the main ones can be listed as :
- GEOSYNTHETIC CLAY LINERS
All of the above-mentioned products can either be used independently or as a system by combining multiple layers of each in order to produce a robust engineered geosynthetic “system” which significantly contributes to the protection of our environment.
GEOSYNTHETICS are now universally accepted design and construction materials as they:
- Provide technical and cost advantages over more traditional methods of construction.
- Offer technical advantages over conventional materials in areas of active and dispersive soils and heavy clays
- Maintain flexibility and integrity when more rigid materials will crack.
- Reduce layer thickness, increase available void space and reduce costs of construction.
- Follow precise MQA (manufacturing quality control) and CQA (construction quality control) procedures applied in manufacture and construction.
- Are highly durable, resistant to weathering and climatic effects and Offer resistance to a wide range of chemical solutions.
- Are flexible both in nature and in use and can be used for constructing around irregular geometrical profiles.
- Are safe for long-term storage of potable water because they are non-toxic and chemically inert.
CONTAINMENT & STORAGE
Geomembrane Liners are continuous flexible sheets manufactured from one or more geosynthetic materials. They are relatively impermeable and are used as liners for fluid or gas containment and as vapour barriers . Geosynthetic clay liners (GCLs) also act as hydraulic barriers either independently or as composite liners in conjunction with Primary Geomembranes by containing the stored liquid and preventing its seepage to the underlying soil.
The excellent tensile mechanical properties of woven or non woven geotextiles, in conjunction with the soil’s good compressive but poor tensile properties, improve the total system’s strength. They are ideal for reinforcing road and railway embankments, slopes and retaining walls. Geogrids can also be used to increase the underlying soil’s bearing capacity and offer cost and construction time savings. The use of these products Improves soft soil bearing capacity. •Distributes stresses and loads across the road construction layers. •Reduces vertical deformation. •Reduces construction, operational and maintenance costs.
The hydraulic properties of woven or non woven geotextiles help to establish structural stability by controlling excess amounts of water during and after construction, allowing for adequate liquid flow while maintaining limited soil loss within the plane of the geotextile. Furthermore, drainage geonets and GeoComposites facilitate in – plane water flow under high surcharge loads such as those experienced in landfills, TSF and heap leach stacks, eliminating the need for thick gravel drainage layers thus offering cost, void reduction and construction cost savings.
FILTRATION and DRAINAGE
woven or non woven geotextiles act as a filter by allowing water to move through the soil while retaining all soil particles. It is used to prevent soils from migrating into aggregate or pipes while maintaining flow through the system.
The woven or non woven geotextile acts to separate two layers of soil that have different particle size distributions. For example, geotextiles are used to prevent road base materials from penetrating into soft underlying soft subgrade soils, thus maintaining design thickness and roadway integrity. Separators also help to prevent fine-grained subgrade soils from being pumped into permeable granular road bases.
Non woven geotextiles offer optimal protection to Geomembrane liners, pipes, structures and surface coated materials that may otherwise experience damage from contact with sharp protrusions such as stones, debris, roots or subgrade unevenness. The geotextiles’ thickness and mass are directly proportional to the amount of protection that they can offer.
Nonwoven geotextiles can be used independently or in conjunction with woven geotextiles for create geobags that can be utilized for erosion control of slopes, shoreline protection and river bank flood control. woven or non woven geotextiles may also be used directly below rip rap or Reno mattresses to prevent fines loss along canals and shorelines,
STRESS RELIEF geotextiles with special properties allow for the delayed progression of differential stresses between a new asphaltic overlay and an old road surface. This translates to reduced reflective cracking and crack propagation between old and new road surfaces.
