Erosion Protection of Steep Cut Slopes - Case Study
In May of 1995, 70,000 sf of large-cell (GW40V) GEOWEB® slope protection system was utilized on Phase II of the Cyprus Miami Open-Pit Mine to stabilize the cut slopes upon completion of copper extraction at the site. Aggregate available on site was used to infill the GEOWEB 3D structure and provide erosion resistance and slope-surface stability on slopes with 70-ft. slope lengths, and as ...

Non-Hazardous Landfill - Case Study
Municipal solid waste landfill is site for domestic day-to-day waste disposal. Its also known as tip, rubbish dump, dumping ground, etc. Material stored at solid waste landfill is isolated from the environment by sealing layer which can be HDPE or LDPE or even PVC geomembrane. If such geomembrane leaks, the contaminant from landfill is spreading in direction of the groundwater flow. This way it ...

Why the installation of geotextile is beneath the geomembrane
The black impermeable geomembrane is also the HDPE membrane. This geomembrane material has only a single layer of plastic, which is prone to aging during use. Thus, laying a layer of geotextile on the surface can solve this problem. So how thick should the surface geotextile be laid to protect the geomembrane? The thickness of geotextile ranges from 110 to 600g is a common type. The thicker the ...

What are the types of geotextiles?
Geotextile is a new type of geotechnical construction material, its raw material is polyester, polypropylene, acrylic, nylon and other high molecular polymer synthetic fibers. Because of its different manufacturing methods, it is divided into two types: there are two types of woven geotextile and non-woven geotextile. General engineering uses non-woven geotextiles. Geotextiles have many functions ...

How to Choose Geomembranes in Water Conservancy Project Construction
As a popular new technology, the geotechnical impermeable membrane is used at home and abroad due to its better anti-seepage effect. The combination of geotechnical impermeable membrane and geotextile forms a composite geotechnical impermeable membrane. The impermeable membrane protects the geomembrane from being punctured by gravel or sharp objects and prevents the positional deviation between ...

Needle Punched Geotextile Separator for Oxidation Pond Project in China - Case study
Geotextile separator is the placement of a flexible porous geotextile between soil and HDPE geomembrane liner to protect the anti seepage lining system from puncture. The short fiber needle punched geotextile is manufactured from polypropylene staple fibers and combines high water flow rate and durability while providing excellent soil retention, along with excellent physical and hydraulic ...

Application of Geomembrane Dam anti-seepage Technology in Hydraulic Engineering Construction
Geomembrane is used for its good anti-seepage effect, and the combination of Geomembrane and geotextile forms a composite Geomembrane. Being punctured by those gravel or sharp objects also prevents the position offset between the geotechnical impermeable membrane and the geotextile. Thus, Geomembrane can solve various leakage problems in hydraulic engineering construction. To see video, please ...

Tailings Pond Geomembrane Construction Plan and Construction Precautions
The development of the mining industry brings not only a large amount of ore but also many tailings problems to be solved. Yet, tailings stored in tailings ponds often contain a large number of metals, heavy metals, and mineral processing residues. Once environmental pollution occurs, the consequences will be very serious. Thus, anti-seepage measures are usually taken for tailings ponds. The ...

The Usefulness of Non-Woven Fabrics Today and Its Future
Nearly every place you sit or stand has a nonwoven fabric. It could be a coffee filter, a tea bag, a mask, diapers, tissues for contact lenses, or other such items. This fabric now has more significance because of the current circumstances and the times we went through because of Covid, yet its market has expanded through time. What is Non-Woven? The most traditional and basic types of textiles ...

What are the Applications of Geocells?
The geocell is a mesh-like cell structure formed by strong welding or riveting of high-strength HDPE or PP copolymer broadband. It expands and contracts can be folded when transported, unfolded when used, and filled with sand, soil, rock, gravel, or concrete to form a structure with strong lateral restraint and high stiffness. It can be used as a cushion to deal with weak foundations to increase ...
