What is Geogrid Reinforcement? Geogrid is the geosynthetic material made from polymers such as polypropylene, polyethylene or polyester. Geogrid is the ideal material used to reinforce soils and similar materials. The main applications of geogird are retaining walls reinforcement, subsets or subsoils below roads or structures reinforcement, etc. Compared to soil, geogrid are strong in tension. Geogrids are manufactured into high strength reinforcement grid that comes in rolls of various sizes and strengths. The soil can strike through the apertures and the two materials interlock together to give composite behavior. The geogrid can delivery strength and longevity to the wall to help prevent wall failure; BPM brand HDPE geogrids are resistant to biological degradation and naturally encountered chemicals, alkalis and acids, etc.
Geogrid Functions
The primary function of geogrid is reinforcement. 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. Geogrid reinforcement provides engineers with a range of solutions for engineering construction.The different methods of manufacture create products that look and feel quite different. The correct use of a geogrid can offer many benefits to a scheme such as increasing the speed of construction, reducing the quantity of soil that’s needs to be imported to a site, etc.
Now, geogrids are commonly used for soil reinforcement applications such as retaining walls, steepened slopes, bridge abutments, embankments, embankments over soft soils and waste containment, as well as subbase or subsoil below roads or structures. Geogrids can improve the structural integrity of soils in roadways, walls and slopes by reinforcing and confining fill materials and distributing load forces. Geogrids are the answer for designers, developers and contractors facing the challenges posed by sloping ground and soft subgrades. Geogrids help soils stand at virtually any desired angle in grade separation applications. In retaining wall and slope applications, geogrids can be combined with a wide variety of facing elements to produce the desired aesthetics for any project. Geogrids provide support for the construction of access roads, highways, berms, dikes and structure applications that previously required the use of expensive over-excavating or piling methods on weak subgrades. Geogrids are also used in base reinforcement applications to reduce aggregate thickness requirements or extend roadway performance life.
Geogrid Applications
(1)Retaining walls. The soil behind retaining walls can exert a tremendous amount of pressure on the blocks so it is very crucial to use a high quality geogrid in-between the blocks to help alleviate that pressure and keep the wall from falling over.
(2) Pavements, Embankments and Raft Foundations. In the engineering construction, geogrid offers high tensile stiffness, excellent resistance to damage during the construction process or environmental exposure.
(3)Dewatering drainage filtration. Composite geogrid to separate building materials with different physical properties such as soil and sand, sand and gravel, soil and concrete, etc. Keep the two or more materials from losing or mixing, and maintain the overall structure and function of the material, such as the effective isolation between the roadbed and the foundation, the foundation and the embankment, the geomembrane and the sand draining layer.
(4 )Slope Stability Systems. Geogrid is able to maintain the tensile reinforcement load and efficiently transfer that tensile load into the surrounding soil.
(5) Landfill and Environmental Barrier Systems. Geogrid is inert to biological degradation and resistant to naturally encountered chemicals, such as alkalis and acids.
(6)Surfacing Reinforcement. Geogrid is used to help retard reflective cracking in the asphaltic layers within flexible and composite pavements.
(7) Water Management Systems. Geogrids with a fabric backing to help with installation and provide a water retardation layer or waterproofing layer,and it also has moderate tensile strength for reinforcement.
