Description

Introduction

Composite geogrid is a high-strength, high-stability geomaterial, primarily composed of polypropylene and glass fibre. With tremendous tensile electrical energy and rigidity, it can efficiently adorn the steadiness and bearing potential of soil.

Biaxial geogrid composite is a geocomposite made of bi-axial polypropylene (PP) geogrid, warmness bonded to a prolonged fiber non-woven polyester geotextile that acts as a filter and soil separator. This geogrid is manufactured the utilization of a punching and drawing approach whereby the polypropylene sheet is stretched in two directions, pc (longitudinal) and cross-machine (transverse). The give up end result is a monolithic and isotropic geogrid with thick and significant ribs, thick essential nodes, and uniform rectangular apertures. Engineered to be robotically and chemically regular in aggressive soil environments, this geocomposite lets in sub-base drainage to aid retain structural stability, and is very splendid in preserving luxurious imported cloth from being contaminated with the aid of 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 higher the tensile strength, shear strength, and erosion resistance of soil, and beautify the common stability and bearing functionality of soil.
Distributed load: Through stress transmission, composite geogrids can disperse the load into the soil, reducing contract and deformation of the soil.
Preventing landslides and flooring erosion: Composite geogrids can be utilized to soil structures such as slopes and embankments to amplify the soil's anti slip plausible and give up landslides from occurring. At the equal time, it can moreover correctly stand up to ground erosion such as wind erosion, water erosion, and wave impact.
Permeable drainage and anti-seepage: Composite geogrids have a high-quality diploma of permeability, which can promote the drainage of water indoors the soil and minimize the chance of soil liquefaction and leakage.
