Description

Introduction

Composite geogrid is a high-strength, high-stability geomaterial, mostly composed of polypropylene and glass fibre. With extraordinary tensile electricity and rigidity, it can efficaciously beautify the steadiness and bearing ability of soil.

Biaxial geogrid composite is a geocomposite made of bi-axial polypropylene (PP) geogrid, warmness bonded to a lengthy fiber non-woven polyester geotextile that acts as a filter and soil separator. This geogrid is manufactured the usage of a punching and drawing technique whereby the polypropylene sheet is stretched in two directions, computer (longitudinal) and cross-machine (transverse). The end result is a monolithic and isotropic geogrid with thick and vast ribs, thick imperative nodes, and uniform rectangular apertures. Engineered to be routinely and chemically steady in aggressive soil environments, this geocomposite lets in sub-base drainage to assist preserve structural stability, and is very wonderful in maintaining luxurious imported fabric from being contaminated by way of migration of fines from the saturated base soils.

Applications

Composite geogrid is widely used in roads, railways, embankments, rivers, harbours and other projects to improve the overall performance of the soil and to prevent soil erosion and landslides.

Working Drawing

Strengthening soil: Composite geogrids can make bigger the tensile strength, shear strength, and erosion resistance of soil, and enhance the average balance and bearing capability of soil.
Distributed load: Through pressure transmission, composite geogrids can disperse the load into the soil, decreasing contract and deformation of the soil.
Preventing landslides and floor erosion: Composite geogrids can be utilized to soil buildings such as slopes and embankments to enlarge the soil's anti slip potential and stop landslides from occurring. At the identical time, it can additionally efficiently withstand floor erosion such as wind erosion, water erosion, and wave impact.
Permeable drainage and anti-seepage: Composite geogrids have a positive diploma of permeability, which can promote the drainage of water interior the soil and decrease the danger of soil liquefaction and leakage.
