E'GRID™ Biaxial Geogrids
Our E'GRID Biaxial geogrids can solve pavement problems by providing omni-axial reinforcement to granular sub-bases, capping layers & railway ballasts in areas of weak or variable soils. When granular particles are compacted over these grids, they partially penetrate and project through the apertures to create a strong and positive interlock.
The load dispersal effect from the interlocking mechanism increases shearing resistance within the soil, improving compaction and allowing the sub-base thickness to be decreased, ultimately reducing construction time and costs. The product can be employed in single or multi layers.
The tough platform created provides tremendous load dispersal, allowing previously weak soils to be reclaimed for foundations, motorways, railways and airport runways. Biaxial geogrids are available in standard and large aperture sizes, to suit any fill material.

Benefits of E'GRID biaxial geogrids
Network Rail approval for E'GRID
Our E’GRID 3030L Biaxial Geogrid is approved by Network Rail with Certificate of Full Acceptance number PA05/05826. To receive the Certificate of Full Acceptance, E’GRID geogrid underwent a vigorous auditing process and Wrekin Products had to provide justification for the product by demonstrating monetary, safety and performance benefits to Network Rail.
The approved E’GRID 3030L polypropylene biaxial geogrid features a large aperture to reinforce the railway ballast layer. This reduces ballast settlement and extends the time between subsequent maintenance work following ballast renewal. The reinforcing element is a Specific Condition of Network Rail acceptance, which requires CE Marking in accordance with BS EN 13250 for reinforcement materials used in contact with ballast.
The high tensile strength design of Wrekin Products’ innovative E’GRID geogrid is widely recognised as an effective method of stabilising ballast or soil through reinforcement. The high-strength polymer grid interlocks with the ballast or stone, confining the material to improve load dispersal and limit lateral movement under load.
To receive the Certificate of Full Acceptance, E’GRID geogrid underwent a vigorous auditing process and Wrekin Products had to provide justification for the product by demonstrating monetary, safety and performance benefits to Network Rail. In general, only accepted products are allowed to be used on the rail infrastructure.
