High tensile strength
Available grades from 15 to 50 kN/m support reinforcement requirements for a range of transportation and civil-engineering applications.
Biaxially Stretched Plastic Geogrids
Polypropylene biaxial geogrids for subgrade reinforcement, pavement reinforcement and slope-stabilization applications.
Biaxially stretched plastic geogrids provide balanced tensile performance and are used in transportation infrastructure, bearing-ground reinforcement and slope-protection systems.
Product Overview
0104
Biaxially stretched plastic geogrids are polypropylene reinforcement geosynthetics designed for subgrade improvement, pavement reinforcement and load-distribution applications. Their tensile performance is defined across multiple grades and they are supplied for a range of transportation and civil-engineering uses.
Typical uses include reinforcement of highways, railways and airports, as well as bearing-ground reinforcement for large parking areas and wharf freight yards. They can also be used for secondary reinforcement of slopes after uniaxial geogrid reinforcement, slope strengthening, erosion-control works, culvert reinforcement, slope protection along railways and highways, and reinforcement in mining and tunnel projects.
